Type material

Syntypes?

PACIFIC OCEAN • 1 spec.; Gulf of Panama; depth 511 ftm (= 934 m); USNM 97069 • 1 spec.; Ecuador, off Manta ; depth 401 ftm (= 733 m); USNM 123125 .

Remarks

The shell differs significantly from any species of Leucosyrinx due to its very short siphonal canal and the anal sinus being situated in the lower part of the subsutural ramp. McLean (1971a) illustrated the species’ radula, but due to the small size of the photograph, little can be discerned, except that it consists solely of duplex marginal teeth. Powell (1966) attributed the species to Burchia Bartsch, 1944 ( Pseudomelatomidae ), and we concur with this classification.
