Type material

Syntypes

EAST AFRICA • 4 specs; off Brawa; 1°40′ S, 41°47′ E; depth 693 m; Valdivia, stn 251; ZMB Mol 109379 .

Remarks

The largest type specimen has a SL of 10.6 mm, appears to be adult, and was illustrated by Thiele (1925). Conchologically, it possesses all the characteristics of Leucosyrinx . The original illustration shows a strongly angular shell base, although it is somewhat more obtuse in the actual specimen. In shell outline and size, it resembles L. lozoueti sp. nov., which, however, has a different spiral sculpture with much finer, uniformly spaced cords. Powell (1969) attributed several specimens to this species with shell lengths up to 53 mm, collected by the John Murray expedition in the Gulf of Aden at a depth of 1040 m.

Distribution

East Africa to Gulf of Aden, 693–1040 m.
