50 BULLETIN OF THE 
of hermit-crab (Sympagurus pictus Smith), remarkable for large bright red 
patches on the basal part of its legs. 
This species may not be a true Urticina. It resembles certain species of 
Sagartia, but no acontia were observed. 
Actinauge VeERRILL, gen. nov. 
Type, A. nodosa, formerly Urticina nodosa (MULLER) VERRILL. 
Large actinians, with the tentacles and upper part of the body capable of 
involution. Integument of body of two kinds ; that of the lower part is firm, 
thick, and more or less coriaceous or parchment-like, with persistent, solid warts 
or tubercles, usually in vertical rows, and sometimes partially covered with a 
thin, chitinous epidermal coating ; that of the upper part of the body forms a 
marginal, brighter-colored band, below the tentacles, where it is soft and Jubri- 
cous, secreting mucus abundantly, and rising into longitudinal ridges, crests, or 
oblong tubercles, which run to and unite with the bases of all the tentacles. 
The basal disk may be broad and flat, adherent, or it may be bulbous, clasping 
mud, or it may ensheathe the branches of Gorgoniz, etc. Tentacles long and 
large, contractile. Lips with large folds and gonidial grooves. 
This genus, like Actinernus, has marginal prolongations of the wall, running 
to and uniting with the outer bases of all the tentacles, but in Actinernus there 
is no specialized submarginal zone, and the body is not verrucose. 
It is also closely allied to Urticina Ehr. (Tealia Gosse), of which the type 
is U. crassicornis, But the latter has the integument soft and lubricous over 
the whole body, and there is no marked specialization of the submarginal zone; 
the tubercles, when present, are small, not much thickened, and of the nature 
of true suckers for attaching foreign substances; and when not in use may so 
contract as to disappear entirely; the submarginal zone is nearly smooth, with 
a definite upper margin, and there are no vertical ridges running in on the 
disk to join the bases of the tentacles, as in this genus and Actinernus.

This large species is very abundant in deep water, along our coast, and 
northward to the Grand Banks. 
It varies greatly in appearance, especially when contracted in alcohol. It is 
capable of contracting to a much greater extent than U. callosa and Actinernus 
nobilis, and when preserved, the upper part of the column is generally strongly
