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
