Leucosyrinx herilda

Leucosyrinx herilda (Dall, 1908) Fig. 33F Gemmula herilda Dall, 1908: 266. Leucosyrinx herilda – McLean 1971b: sp. 1670. Type material Holotype GULF OF PANAMA • depth 1672 ftm (= 3057 m); USNM 123091. Remarks The holotype of the species is a dead-collected incomplete shell (SL 18+ mm). Judging from the growth lines, the shape of the anal sinus corresponds to that of other species of Leucosyrinx. Therefore, we confirm its generic position in Leucosyrinx, as was suggested by McLean (1971b). The species is very similar to Leucosyrinx powelli (Rehder & Ladd, 1973) collected at Agassiz Guyot in the central Pacific albeit at shallower depths (1581–1617 m). Both species can be conspecific, but due to the large distance between the type localities and large difference in depths, we presently consider them as two separate species. Distribution Type locality.
