Pleurotonia (Pleurotomella) Pandioms VeiTill, sp. nov. 



Shell large, thick, dull 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 growth, which 

 recede in a broad curve on the subsutural band ; numerous fine, 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 aperture, 19'""'; its breadth, 5.5'""'. 



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



PleuTOtoma Carpenter! Verrill & Smith. 



Amer. Jonru. Sei., xx, p. 395 (published Oct., 1880). 



Only a few specimens were taken, stations 871 to 873, in 8G to J 15 

 fathoms. 



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

 ination no specimens with the animal. 



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

 a. O. Sars, Moll. Eeg. Arct. Norv., p. '220, pi. 17, fig. 8. 



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

 fully to this species, Avero taken at station 894, in 3G5 fathoms, off Xew- 

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



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

 are five revolving, nodulous carina? 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 ; tlie 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 carinne the surfiice is 

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

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

 between the carintT?, and produce 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 Up 

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



The principal difi'erence between our specimens and the form figured 

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

 round the periphery, instead of one. 



Taranis pulcliella Verrill, sp. nov. 



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

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

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