appendage ; the appendage fragil, narrow-trigona!, consisting 

 of doubled laminae, the laminae opened at the front but closed 

 at the back, with one or two processes of growth wrinkles, 

 showing that they arc the relics of the transposed posterior 

 canal. The umbilical carina has also 7-10 long and narrow 

 semitubular, recurved appendage, continuous at the base and 

 visible in the perforation, the inner the smaller. The both 

 sides of the periphery and the part above the umbilical carina 

 are concave, but the other pait of the body whorl somewhat 

 convex ; the last one-third of the body whorl gradually descend- 

 ing. The detached aperture obliquely trigonal, the lower part 

 tapering and receding, with a posterior canal on the upper part 

 of the outer lip, and a long, recurved, spout-shaped anterior 

 canal ; the lip thin, but thickened within, slightly recurved, with 

 a trace of some five teeth within. The surface smooth, 

 sculptured irregular minute growth-lines and obscure spiral 

 stria-, running into the foliated shoulder carina. 



The operculum dull reddish-brown, slightly cuivcd, with 

 a nucleus at the lower part of the outer margin.

Kashiwa-jima, Tosa ; types in my collection. 



At first I believed this peculiar precious specimen from the 

 deep sea was a young Latiaxis viawce, but since I have got 

 three other such specimens and several true young mawce, and 

 have ascertained that these two are quite different. L. pilsbryi 

 1. distinguished from mawcz by the lesser deflection of the body 

 whorl hi front, the foliated shoulder carina not so recurved, the 

 sculpture not so coarse and the ivliite surface without fresh tint. 



I am glad that I can have the honour of naming such a 

 fine species in honour of Dr. Henry A. Pilsbry, to whom we 

 owe almost all our knowledge of the Japanese shells.
