anteriorly; posterior angle acute; outer lip very strongly protracted 

 between the posterior angle and the base, forming a decidedly claw- 

 like element; inner lip decidedly curved, revolute with the posterior 

 half appressed to the base; parietal wall covered with a thin callus. 



The type (Cat. No. 251283, U.S.N.M.) was dredged by the United 

 States Bureau of Fisheries steamer Albatross at station 2808, off the 

 Galapagos Islands, in 634 fathoms, on coral sand bottom, bottom 

 temperature 40°. It has nine whorls and measures — length, 3 8 

 mm., diameter, 1.3 mm. 



SABINELLA BAKERI, new species. 



Plate 43, fig. 5. 



Shell small, very broadly conic, creamy-white. All the whorls 

 moderately roimded, excepting the last which is very strongly 

 rounded. All marked by rather prominent lines of growth, and rather 

 numerous irregularly disposed varices, of which there are sometimes 

 several to a single whorl. Suture moderately constricted. Periphery 

 of the last whorl inflated, strongly rounded. Base short, strongly 

 rounded, marked like the spire. Aperture very large; posterior angle 

 acute ; outer lip thin at the edge, decidedly produced, and protracted 

 in the middle to form a strong claw-like element; inner lip slender, 

 slightly curved, somewhat revolute, free for its entire length; parietal 

 wall glazed by a thin callus. 



The unique type (Cat. No. 215786, U.S.N.M.) was collected by Dr. 

 Fred Baker, at San Diego, Cahfornia. It has nine whorls and 

 measures — ^length, 2.7 mm.; diameter, 1.1 mm. 



SABINELLA OPALINA de Folin. 



Plate 43, fig. 7. 

 Eulima opalina De Folin, Les Meleagrinicoles, 1867, pp. 67, 68, pi. 6, fig. 7. 



"Shell imperforate, rather elongate, opaque, shining, opaline, 

 darkly spotted with red. Spire conic, attenuated, tapering to a sub- 

 acute apex. Whorls, 10 in number, increasing slowly in diameter, 

 united by a simple suture, final whorl equal to one-third the altitude 

 of the entire shell, strongly depressed at the base. Aperture sub- 

 quadrate, the margin sHghtly thickened, columella reflected. Long., 

 0.0035; diam., 0.0018. 



"This, again, is one of the prettiest of the species. It is red, 

 elongated, but less so than those which precede it, and for this reason 

 its diameter is relatively greater. 



"It is conspicuously conic, and for this reason appears less acumi- 

 nate, although its apex is acute. The spire is made up of 10 whorls, 

 which increase slowly in diameter, but which increase more rapidly 

 in diameter than in altitude. The fuial whorl, which is almost one- 

 third as long as the entire shell, is imperforate, an d very much depressed
