Leucosyrinx powelli

Leucosyrinx powelli (Rehder & Ladd, 1973) Fig. 33G Comitas powelli Rehder & Ladd, 1973: 45, pl. 3 figs 11–12. Type material Holotype PACIFIC OCEAN • Agassiz Guyot; 17°58.5′ N, 178°14.2′ E; depth 865–884 ftm (= 1581 – 1617 m); USNM 703267. Remarks The holotype is the only known specimen, with SL 13.0 mm. Although the outer lip of the aperture is broken, judging from the growth lines, the shape of the anal sinus corresponds to that of other species of Leucosyrinx as defined here. The species is very similar if different from Leucosyrinx herilda (Dall, 1908) (see Remarks to L. herilda). Distribution Type locality.
