Remarks.
Aldrich (1889) did not give a name for the " Alycaeus sp.", species he figured and described, because he thought it might be A. spiracellum , which he was unable examine for comparison. He mentioned that "if new, I propose the name Alycaeus broti for it". This action does not make the name available, because under ICZN Art. 11.5 "To be available, a name must be used as valid for a taxon when proposed", which was not the case for A. broti ; therefore, the name Alycaeus broti is not available. Smith (1895) mentioned that he compared A. everetti specimens with his " A. broti ", and they were identical.
Protoconch elevated, no spiral lines visible; R1 with very fine, irregular ribs and spiral lines; R2 short, with sharp, straight, widely spaced ribs.
