with six revolving carine, besides one or two on the canal; one is just 
below the suture; the three largest surround the periphery, the median 
one most prominent. Between the subsutural and second earinz the 
surface is concave and crossed by numerous elevated, thin, curved rib- 
lets, corresponding to the labial sinus; similar but less prominent and 
less curved riblets cross the interspaces between the other carinz, but 
do not cross the carine themselves. Penultimate whorl with the sub- 
sutural and two peripheral carine. Preceding whorls without distinet 
canine, except the subsutural one, but with the curved, transverse, raised 
riblets well developed. Nuclear whorls very small (surface eroded). 
Aperture narrow, angular; canal short, slightly turned to the left; outer 
lip. with a distinct, evenly rounded sinus below the subsutural carina. 
Columella slightly ineurved and flattened. Length, 2.20""; breadth, 
.90""; length of body-whorl, 1.40"; of aperture, .95"™", 
Station 892, in 487 fathoms; one specimen. 
Marginella roscida (?) Ravenel. 
A single dead specimen, closely resembling this species, was taken at 
Station 865, in 65 fathoms. 
Tritonofusus latericeus (MOll.) Morch. 
Sipho latericeus G. O. Sars, Moll. Reg. Arct. Norv., p. 276, pl. 15, fig. 8; pl. x, 
fig. 24 (dentition). 
Several specimens, apparently of this species, were taken at stations 
894 and 895, in 238 to 365 fathoms, off Newport. It had previously been 
dredged in the Gulf of Saint Lawrence by Dr. J. W. Dawson. 
Our shell is long-fusiform, with an elevated, acute spire; whorls 
eight, moderately convex, crossed by strong, prominent, rounded ribs 
(about eighteen on the last whorl), separated by concave interstices, 
wider than the ribs; whole surface covered with fine and regular spiral 
grooves, defining raised spiral lines of about double their width; these 
lines cross. the ribs as well as their interspaces. Nuclear whorl small, 
a little eccentric and incurved. Aperture long-ovate, narrow. Canal 
somewhat elongated, nearly straight, narrow; the outer lip is con- 
tracted or incurved at its base. Length, 20°"; breadth, 8°"; length of 
aperture, 10"; its breath, 6". 
Neptunea (Sipho) czelata Verrill, sp. nov. 
Shell resembling the last, small, subfusiform, with an elevated spire, 
which is less acute than in the preceding, while the aperture is shorter 
and the canal is shorter and more recurved than in that species. Whorls 
six, moderately convex, with impressed sutures, the upper whorls de- 
creasing more rapidly. Nuclear whorls very small, regular, smooth, not 
distinetly ineurved. Sculpture broad, rather prominent, rounded ribs, 
with wider concave interspaces, and over the whole surface numerous 
small, narrow, unequal, raised spiral lines, separated by wider grooves. 
The whole surface is also covered with very fine and regular raised lines 
of growth, which cross and roughen the spiral raised lines, and are more 
Proce. Nat. Mus. 80 24. Dee. 2h, 18890.
