Length, 9 m.ni.: breadth, 2 m.m. 



LocaHty : Type from 40 fathoms three miles east of 

 Schouten Island, with one other juvenile; and in 100 

 fathoms seven miles east of Cape Pillar two fragments. 



Easily separated from our other species by its remark- 

 able apex. 



EULOIA EXPAXSILABIL\, X.S. (PL. XV., 

 FIG 26.) 



Shell small, white, smooth, thin, tapering and slightly 

 bent; whorls eight, rounded, the first minute, but increas- 

 ing rapidly; body whorl inflated; suture well impressed; 

 mouth large, angled above and below; outer lip roundly 

 expr^nded; colu.mella straightish, well reflexed. 



Length, 3.5 m.m.; breadth, 1.5 m.m. 



Locality : Type from 100 fathoms seven miles east of 

 Cape Pillar; also from 40 and 80 fathoms east of Schouten 

 Island four examples. 



Remarkable for its small spire, large body whorl, and 

 widely expanded mouth. 



ACLIS COLUMXARIA, X.S. (PL. XV., FIG. 2j>^ 



Shell small, conical, high, pure white, somewhat 

 liyaHne, smooth, and glossy; whorls six, rounded, but 

 widest a little above the suture, which is well impressed; 

 apex blunt and rounded; mouth oval, angled above, 

 round below; outer lip thin and simple, inner lip roundly 

 concave. 



Lender a high magnification numerous fine spiral 

 grooves are seen on the whorls. 



Operculum (in a cotype) light yellow, thin, ovate, 

 pointed above, the nucleus near the middle of the base,, 

 with distinct \'-shaped lines of growth above. 



Length, 5 m.m.: breadtli. 2 m.m. 



Locality : Type from 100 fathoms seven miles east of 

 Cape Pillar, with tv.clve otliers. 



I have placed this with Aclis because of its strong 

 likeness to A. minutissima Watson from Torres Straits 

 — Challenger Report. It is distinguished from that species, 

 by its immensely greater size and the rounded columella.
