between the wrinkles of the upper parts. Surface of the upper half often 
more or less nodulous and wrinkled, becoming more so toward the margin, 
where the elevations become elongated ridges and crests. Base clasping the 
denuded axis of Balticina and other Pennatulide where these have been in- 
jured, most frequently on the upper end, but not uncommonly on other parts 
of the rachis, beyond which the polyps may be still alive. The lateral lobes of 
the base meet and coalesce around the axis, so as to form a tubular sheath, 
considerably beyond the breadth of the body. When two or more are crowded 
together, their basal disks unite where they come in contact, thus entirely cov- 
ering the axis that supports them. Tentacles numerous, covering much of the 
disk, rather short, thick, tapering, but not seen in full extension. 
Color of body usually pale salmon or flesh-color, with streaks of brown, in 
wrinkles; disk deep orange-brown, with darker brown radii; tentacles salmon- 
brown.

It was dredged at several stations, off Martha’s Vineyard, in 168 to 245 
fathoms, on Balticina, by the,U. 8. Fish Commission, in 1881 and 1882. 
Numerous specimens, from the various fishing banks off Newfoundland and 
Nova Scotia, have been brought in by the Gloucester fishermen. These are all 
on Balticina, and mostly from 200 to 300 fathoms. 
Actinostola Verritt, gen. nov. 
Type, Urticina callosa VERRILL. 
Size large, integument very thick, firm, leathery, lubricous, not very con- 
tractile. Column covered with large, irregular tubercles, not having the power 
of adhering to foreign substances; upper portion not essentially different from 
the rest, the surface being without specialized structures ; margin indefinite, 
continuous with the bases of the smaller outer tentacles. Basal disk fre- 
quently smaller than the upper part of the column, usually concave and 
enclosing mud. Tentacles numerous, short, thick, more or less scattered over 
the disk, the inner ones much the largest, longitudinally suleated, imperfectly 
contractile, not deciduous. Disk usually deeply concave ; mouth large, with 
large, strongly lobed lips, and large gonidial grooves. The walls of the body 
are very thick, firm, leathery, and, although capable of considerable contraction 
longitudinally and transversely, they seem to be incapable of contracting sufli- 
ciently to withdraw the disk and tentacles; when handled, the column fre- 
quently becomes collapsed and longitudinally folded, and frequently takes an 
hour-glass shape, the disk and tentacles remaining fully exposed, although the 
tentacles may be very much diminished in size. 
This genus is allied to Bolocera, Urticina, and especially to Actinauge. From
