            <p> Family  Cyclocaridae Lowry &amp; Stoddart, 2011</p>
            <p>Diagnostic description. “ Head exposed or partially covered by pereonite 1, slightly deeper than long, with or without cheek notch. Antennae, calceoli present or absent in male. Antenna 2 peduncle article 3 without distal hook. Epistome and upper lip separate. Epistome with proximal portion not produced. Mouthpart bundle subquadrate. Mandible incisors well developed, asymmetrical, left straight, minutely serrate or minutely and weakly scalloped, right convex, smooth; left lacinia mobilis rod-like; accessory setal row with more than 5 robust setae, without distal setal tuft; molar a setose tongue; palp inserted distally. Maxilla 1 inner plate with pappose setae along medial margin; outer plate with setal-teeth in 7/4 crown arrangement, setal teeth large, slender; palp large, with apical robust setae. Maxilla 2 inner plate significantly shorter than outer plate, inner plate without oblique row of facial setae. Maxilliped outer plate present, medial setae small, blunt or bead-shaped, with apical slender setae; palp 4-articulate, article 4 well-developed.</p>
            <p>Gnathopod 1 simple; coxa vestigial; ischium long; carpus long; propodus small; dactyl slightly curved. Gnathopod 2 coxa vestigial. Pereopods all simple; distal spurs absent. Pereopod 4 coxa with posteroventral lobe weak. Pereopod 5 coxa posterior lobe deeper.</p>
            <p>Uropod 3 biramous. Telson long, deeply cleft. (Modified after Lowry &amp; Stoddart, 2011, modifications in bold text).</p>
            <p> Remarks. Lowry &amp; Stoddart (2011) erected the family  Cyclocaridae in recognition of the distinctive characters of  Cyclocaris .  C. lowryi sp. nov. and  C. franki sp. nov. resemble  C. tahitensis and  C. guilelmi but have characters of the head and incisor process that require emendation of the diagnostic description. Examination of material of  Cyclocaris guilelmi at the Natural History Museum, London (including the type of  Cyclocaris faroensis Norman, 1900 ) reveals that the habitus illustration of this species by Sars (1900) of subequal lobes of the pereopod 5 coxa, is erroneous. The diagnostic description has been emended accordingly. </p>

            <p> Genus  Cyclocaris Stebbing, 1888</p>
            <p> Cyclocaris Stebbing, 1888: 664 .— Stebbing, 1906:30.— Barnard, 1969: 338–339.— Barnard &amp; Karaman, 1991: 479.— Lowry &amp; Stoddart, 2011: 58–60. </p>
            <p> Type species.  Cyclocaris tahitensis Stebbing, 1888 , original designation. </p>
            <p> Diagnosis. As for the family. Maxilla 1 palp apically strongly tridentate, each tooth crowned with a robust seta. Species composition.  Cyclocaris tahitensis Stebbing, 1888 ;  Cyclocaris guilelmi Chevreux, 1899 ;  Cyclocaris lowryi sp. nov. ;  Cyclocaris franki sp. nov.</p>
            <p> Remarks. The  Cyclocaridae most closely resemble the  Cebocaridae and can be distinguished by the head being only slightly deeper than long; the presence of eyes; the more strongly asymmetric incisors; the setose molar and the simple non-prehensile pereopods (Lowry &amp; Stoddart, 2011).  C. guilelmi is unusual in having eyes that cover most of the head and that are not destroyed by fixation and preservation. In the remaining three species eyes fade or disappear completely following preservation as was reported for  C. tahitensis (Lowry &amp; Stoddart, 2011) . The two new species each possess four irregular and somewhat variable ocular patches; bright red in the case of  C. franki sp. nov. (Figure 2). In common with some other lysianassoids, the bright red pigment found in the two new species is highly labile in alcohol (Thurston, 1974; Thurston &amp; Bett, 1993). </p>
            <p> Cyclocarids are necrophages to a greater or lesser extent; all species have been caught in baited traps. In common with otherwise unrelated necrophagous lysianassoids such as  Alicella, Eurythenes and some members of the  Uristidae ,  Cyclocaris species share a total loss of the triturating surface on the mandibular molar and a shortening of the inner plate of maxilla 2 (De Broyer &amp; Thurston, 1987; Stoddart &amp; Lowry, 2004; Lowry &amp; Stoddart, 2011; unpublished observations). When fully gorged, the hugely extended sternites of the pereon make specimens of  Cyclocaris very obvious in trap catches (Figure 3). </p>

            <p>Male. Similar to female except for calceoli on both antennae and a longer callynophore.</p>
            <p> Remarks.  C. lowryi differs from  C. tahitensis and  C. guilelmi by the rounded triangular eyelobe. For characters separating  C. lowryi from  C. franki , see under the latter species. </p>
            <p> The lower lip as figured here agrees closely with the illustration of Chevreux (1935) and appears to lack inner lobes. However, the lower lip of the holotype was damaged during dissection. An examination of other specimens shows that inner lobes are present but are very small; much smaller than those shown for  C. guilelmi by Barnard (1959). They project dorsally, i.e. perpendicular to the outer lobes, and are fused with separated, rounded apices. </p>
            <p>Most material has come from baited traps set at abyssal depths, but individuals occupy the benthopelagic zone (present material; Thurston, 1990).</p>
            <p>Distribution. Atlantic Ocean, 8–49˚N. Guiana, Cape Verde, Madeira, Horseshoe, Iberian and Porcupine Abyssal Plains, Portuguese canyons, 3600–5432 m, benthic and abyssopelagic (present material; Thurston, 1990).</p>

            <p>Male. Similar to female except for calceoli on both antennae and a longer callynophore.</p>
            <p> Remarks. This species is most closely related to  Cyclocaris lowryi . It can be distinguished from that species by characters of pereopods 5–7.  C. franki has the basis of peraeopod 5 produced posterodistally, the basis of peraeopod 6 emarginate posterodistally, and peraeopods 5–7 with broad meral articles (length/breadth ratios 1.6, 1.7 and 2.1 respectively). In contrast,  C. lowryi has the basis of peraeopod 5 broadly rounded and produced distally, the basis of peraeopod 6 convex posterodistally, and peraeopods 5–7 with narrow meral articles (length/breadth ratios 2.2, 2.7 and 2.9 respectively).  C. franki can be distinguished from  C. tahitensis by the lack of eyelobes and the broadly rounded posterodistal lobe of coxa 4 of the latter. </p>
            <p> C. franki differs from  C. guilelmi in having subacute triangular eyelobes and four evanescent red-pigmented ocular patches in contrast to the broadly convex anteroventral head margin and permanent yellow-brown ocular pigment covering the whole head of the latter species. </p>
            <p> The single specimen from Monaco Station 1206 close to the Cape Verde Islands, collected at a depth of 1477 m and recorded as  C. tahitensis by Chevreux (1903, 1935) belongs to this species. Chevreux noted that the only differences he could find between the Tahiti specimen (  C. tahitensis ) and his specimen were that pereopods 5–7 were more spinose and the apices of the telson were a little different. </p>
            <p> All known material of  C. franki has been obtained from baited benthic traps. </p>
            <p>Distribution. Atlantic Ocean. Angolan continental margin, 1850–2059 m; Sierra Leone Rise, 1203 m (present material); Cape Verde Islands, 1477 m (Chevreux, 1903, 1935).</p>

            <p> Remarks. This species differs from all others in the genus by the permanent yellow-brown ocular pigment covering the whole surface of the head. The absence of eyelobes separates it from  C. lowryi and  C. franki . The comparison is based on Barnard (1959), the best available account of the species. </p>
            <p> C.guilelmi is a well known Arctic species. It occurs widely at mesopelagic and bathypelagic depths, mostly at 500-2000+m (Stephensen, 1923, Østvedt, 1955, Birstein &amp; Vinogradov, 1958, 1970), but has been recorded in the epipelagic zone (Sars, 1900, Stephensen, 1933). The species is attracted to sediment traps in large numbers (Seiler &amp; Brandt, 1997, Kraft et al. 2013) and has been taken occasionally in baited traps, both benthic, at 1095 m (Chevreux, 1899, 1935), and midwater, at 1800 m (Barnard, 1959). The species appears to breed throughout the year (Kraft et al. 2013). </p>
            <p>Distribution. Disjunct: Arctic Ocean, north-west Pacific Ocean. Norwegian Sea, Greenland Sea, south to the Faroe-Shetland Channel (Norman, 1900, Stephensen, 1923, Østvedt, 1955, Seiler &amp; Brandt, 1997, Vinogradov, 1997, Kraft et al. 2013); Baffin Bay (Stephensen, 1933, Buchanan &amp; Sekerak, 1982); Arctic Ocean, Nansen, Amundsen, Makarov and Canadian Basins (Sars, 1900, Barnard, 1959, Kosobokova et al., 2011); Pacific Ocean north of 39˚N and west of 170˚E (Birstein &amp; Vinogradov, 1955, 1958, 1970).</p>

            <p> Material examined.   Holotype, ca. 17 mm,  Challenger station 279, off Tahiti, collected in a plankton tow net, in a sounding of 768 m. The type material consists of 3 slides (Reg. No. NHMUK 1889.5.15.20). The slides are in poor condition but are recognisable as the specimen used for Stebbing’s original illustrations. </p>
            <p>Remarks. Material collected at the Îles Australes (south-west Pacific Ocean) shows the species to have a large, irregularly-shaped eye which fades with preservation (Lowry &amp; Stoddart, 2011).</p>
            <p> Vinogradov &amp; Vinogradov (1991), Vinogradov (1993) and Lowry &amp; Stoddart (1994) have shown that  C. tahitensis is a widespread, abundant scavenger in the South Pacific Ocean.
