Pleurotoma (Pleurotomella) Pandionis Vorrill, sp. nov. 



Shell large, thick, (lull brownish yellow, with a very acute, elevated 

 spire; whorls nine, very oblique, moderately convex, concave below 

 the suture; whole surface covered with close lines of growtli, which 

 recede in a broad curv^e on the subsutural band ; numerous tine, unequal, 

 raised, spiral lines cover the whole surface, except the subsutural band. 

 The upper whorls are also crossed by sixteen to eighteen blunt, trans- 

 verse ribs, about as broad as their interspaces, most elevated on the 

 middle of the whorls, fading out above and below. Aperture elongated, 

 narrow; sinus broad and well marked, just below the suture; canal 

 short, nearly straight. Operculum absent. Length, 43™'"; breadth, 

 14.5"""; length of aijerture, 19'"""; its breadtb, 5.5'"™. 



A large specimen was taken alive at station 895, in 238 fathoms. 



Pleurotoma Carpenter! Verrill & Smith. 



Amer. Jouru. Sci., xx, p. 395 (published Oct., 1880), 



Only a few specimens were taken, stations 871 to 873, in 86 to 315 

 fathoms. 



This species very likely belongs to Mangelia, but I have had for exam- 

 ination no specimens with the animal. 



Taranis Morchii ? CMalrn) Jeffreys, Annals and Mag., v, 1870. 

 G. O. Sars, Moll. Reg. Arct. Norv., p. 220, pi. 17, fig. 8. 



Two good examples of a prettily sculptured shell, which I refer doubt- 

 fully to this species, were taken at station 894, in 305 fathoms, off New- 

 port, E. I. They do not agree fully with Sard's figure and description. 



Whorls six, the lower ones sharply angnlated and carinated. There 

 are five revolving, nodulous carin^e on the body-whorl, one close to the 

 suture ; the second and most prominent surrounds the periphery ; the 

 other three are on the anterior half; some faint additional ones appear 

 on the canal ; the three preceding whorls have the subsutural and the 

 sharp central carina, and usually the third carina is more or less ex- 

 posed at the suture. Between the first and second carinse the surface is 

 flat or slightly concave. The whorls are crossed by numerous thin, 

 delicate, flexuous, regularly spaced, raised ribs, which are conspicuous 

 betweeu the carince, and i)roduce sharp nodules where they cross them. 

 The nucleus is small, rounded, light chestnut-brown, minutely cancel- 

 lated with microscopic lines running in two directions. Sinus of the lip 

 shallow, rounded. Length, 4'"™; breadth, 2'"'". 



The principal difference between our specimens and the form figured 

 by Sars is that in the latter there are more cariute, two of which sur- 

 round the periphery, instead of one. 



Taranis pulchella Verrill, sp. nov. 



A smaller and more slender species than the preceding, with a more 

 acute spire, and with the carinae sharp, but not nodulous. Whorls 

 seven, angular, the lower ones carinated and shouldered. Body- whorl
