Cladocarpus speciosus, sp. nov. 
Our single specimen is small, unbranched, without gono- 
phores. Stem compound. Pinne slender, not crowded, spread- 
ing at a wide angle. Hydrothece rather short, slightly cam- 
panulate, in a side view the breadth of the aperture is equal to 
two-thirds the depth; a faint median ridge on the front; the 
margin is divided rather regularly into about eleven or thirteen, 
moderate sized, subacute teeth, the outer median tooth, and 
that next to it, on each side, a little longer than the rest ; intra- 
thecal septum well-developed, near the bottom; lateral nema- 
tothecz short, swollen in the middle, narrowed to the aperture, 
margin crenulated; median nematothece short, adnate, except 
at the end, where the oblique aperture faces the hydrotheca, 
margin crenulated. 
Height, 26™; length of pinne, 10™™.

Several specimens of this species were sent to me by Mr. 
J. F. Whiteaves, who dredged them in 1878, in the Gulf of St. 
fathoms, off Greenland, by Friele. It is allied to CG arenaria 
Migh. (=. scrobiculatata MOll.) and to C. carinata Mighels, but is 
a larger and stouter species than either of these, with stronger 
sculpture and more angular and shouldered whorls. The color 
1s dark chestnut-brown. There are, in our specimens, four 
strong revolving ridges on the last whorl; the upper one nod- 
ulous; the lowest, stout, basal; about fourteen transverse sub- 
sutural costs, extend to and join the first revolving ridge, giving 
rise to the small tubercles. On the spire only two spiral lines 
are visible. Length, 4™™; breadth, 25m,
