Variety coronata nov. 
Plate VI. Figs. 8, 8a. 
This variety is chiefly peculiar in having one or two of the upper transverse 
series of verrucee much more prominent than usual, and tipped by a conical, 
often acute point of hard chitinous material, of the same nature as the coating 
over the general surface, but thicker and harder. The lower part of the col- 
umn may be covered with low tessellated verruce, or it may be nearly smooth. 
The base, in nearly all the examples of this variety that I have seen, is flat and 
adherent. The few specimens of this kind in my possession are mostly less 
than an inch in diameter. They are mostly from deep water, 300 to 980 
fathoms. Intermediate states between this and the normal form are not rare. 
From Station 307, in 980 fathoms, there is a peculiar specimen (Figs. 8, 8a) of 
this variety, in which there is a single circle of twelve very prominent, sharp- 
pointed verruce around the retracted summit ; the lower part of the column is 
irregularly wrinkled and covered with a tough and closely adherent dark brown 
epidermis. 
Variety tuberculosa nov. 
Plate VI. Fig. 7. 
This is a remarkable form, perhaps a distinct species. The column is coy- 
ered with large, distinct, irregularly scattered, round or hemispherical, solid 
tubercles, which are persistent. The upper retractile border has irregular, 
strong, longitudinal, unequal crests. The surface of the column is covered 
with a firm dark brown epidermis. The base is broad and adherent to stones, 
lumps of mud, etc. The tubercles in alcoholic specimens are generally white, 
the surface between dark brown. Height in alcohol, 40 to 70mm. ; diameter, 
25 to 45 mm.; diameter of tubercles, 5 to 10 mm. 
I have never seen this variety alive, and therefore hesitate to separate it as a 
species, although it may very well prove to be distinct. I have seen no truly 
_ intermediate forms. 
This variety has often been brought in from various localities, on the fishing 
banks off Nova Scotia, etc., by the fishermen of Gloucester, Mass., and pre- 
sented to the U.S. Fish Commission by them. It has been dredged by the 
U.S. Fish Commission in the Gulf of Maine and off Nova Scotia. It was 
also sent tome by Mr. J. F. Whiteaves, who dredged several specimens of it 
in 1872, in the Gulf of St. Lawrence, off Anticosti Island, in 112 fathoms. 
Actinauge longicornis Verritt. 
Urticina longicornis Verriix, Amer. Jour. Sci., XXIII., March, 1882, p. 222.

This is a very large and beautiful species, remarkable for the large size, 
great length, and delicate coloration of its tentacles, and for the whitish or rosy
