Pleurotoma (Pleurotomella) Pandionis Verrill, 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. pees 43°"; breadth, 
14, 5mm length of aperture, 19°"; its breadth, 5.5%" 
A large specimen was en alive at station 895, in 238 fathoms. 
Pleurotoma Carpenteri Verrill & Smith. 
Amer. Journ. Sci., xx, p. 395 (published Oct., 1880). 
Only a few specimens were taken, stations 871 to 873, in 86 to 115 
fathoms. 
This species very likely belongs to Mangelia, but I have had for exam- 
ination no specimens with the animal. 
Taranis Morchii ? (Malm) Jeffreys, Annals and Mag., v, 1870. 
G. O. Sars, Moll. Reg. Arct. Norv., p. 220, pl. 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 365 fathoms, off New- 
port, R. I. They do not agree fully with Sars’s figure and description. 
Whorls six, the lower ones sharply angulated and earinated. There 
are five revolving, nodulous carinz on the body-whorl, one close to the 
suture; the ea and most prominent surrounds fie 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 carine the surface is 
flat or slightly concave. The whorls are crossed by numerous thin, 
delicate, flexuous, regularly spaced, raised ribs, which are conspicuous 
between the carinz, 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 lip 
shallow, rounded. Length, 4"; rena Dia, . 
The principal difference bercen our specimens and the form figured 
by Sars is that in the latter there are more carina, 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 carine sharp, but not nedulous. Whorls 
seven, angular, the lower ones carinated and shouldered. Body-whorl
