The following additional species are published in the Report of 

 the Challenger Expedition, in which work the group is referred to 

 Litiopidse. 



L. STRIATA, Watson. PI. 53, fig. 80. 



Spirally striated and longitudinally ribbed, the intersections 

 nodulous, style short, cylindrical, whorls convex, suture impressed ; 

 whorls 5, besides 3 smooth whorls of the style; columella a little 

 truncate below. Length, 2'5 mill. 



Tahiti. 

 L. FULVA, Watson. PI. 53, fig. 90. 



Fulvous, narrowly, distantly longitudinally ribbed, more closely 

 spirally striate ; apical whorls 2, smooth, the others 10, convex, 

 periphery slightly angulate ; columella obliquely, slightly truncate. 



Length, 3'3 mill. 



Cape York, N. E. Australia. 

 L. SULCATA, Watson. PI. 53, fig. 91. 



White, spirally striated, the striae obsolete on the middle of the 

 body whorl ; apex scarcely styliform, normal whorls 5, convex. 



Length, T75 mill. 



Cape York, N. E. Australia. 



The appearance of a canal in the figure is caused by a portion of 

 the base of the aperture being broken off. Watson remarks that it 

 may be the young shell of some other genus. 

 L. GONIOCHEILA, A. Ad. PI. 53, fig. 92. 



Thin, vitreous, pellucid, with a single spiral series of milk-white 

 maculations on the middle ; whorls 9, somewhat convex, suture 

 margined. Length, 5 mill. 



Japan. 



This was included among the unfigured species of Eulimidse, in 

 Manual, viii, 286. I am now able to add a figure from the Chal- 

 lenger Report. 



L. LEPIDA, A. Ad. (unfigured.) Japan.
