212 J. EF. Whiteaves—Kecent Dredging operations 
during this cruise have yet to be studied. One living example 
of * Ophioscolex giucialis M. and T. was dredged in 210 fathoms, 
to the southwest by south of the Southwest Point of Anticosti. 
Nore.—I am indebted to Prof. Verrill for the identification of several critical 
species, to whose names an asterisk (*) is prefixed; and the difficult Crustacea, 
whose appellations are preceded by a dagger (+), were kindly determined for me 
Mr. 8. I. Smith. 
Actinozoa.—A few individuals of Pennatu/a aculeata Dan., 
var., and of Virgularia Ljungmanii Koll, were taken in the 
deep-sea mud, together with large tubes apparently belonging 
to Cerianthus borealis Verrill, though the animal of this latter 
species has not yet been taken in the Gulf Cornulariella mo- 
desta Verrill was collected (in 1871) at depths of 220 fathoms, 
between the east end of Anticosti and the Bird Rocks. 
plumosa ? were dredged in the same place. Escharella paimata 
(M. Sars) was also sparingly taken in deep water. 
Mouivusca.—The most abundant species collected at greater 
depths than 150 fathoms are Pecten Greenlandicus Ch., and Arca 
pectunculoides; but Portlandia lucida, P. frigida, Philine quad- 
rata, Cylichna umbilicata Mont., Dentalium attenuatum* ? Say, 
and Siphonodentalium vitreuem Sars also occurred, though more 
sparingly. ‘T'wo living specimens of Cerithiopsis costulata MOll. 
(the Biitium arcticum of Mérch) were dredged in the 220 
fathom locality. 
RUSTACEA.—The deep-sea Crustacea are of unusual interest. 
Among them is a living specimen of Calocaris MacAndre: Bell, 
the first, I believe, that has been observed on the American 
side of the Atlantic. In the same region, four specimens of a 
crustacean were collected, which belong, in my judgment, to 4 
new genus.t In its characters, this genus (for which I venture 
* If the shell described by the late Dr. Gould as Dentaliwm dentale be really the

ving received a number of Norwegian specimens of D. abyssoruim 
through the kindness of Mr. Jeffreys, and compared them with the St. Lawrence 
i ri species, I cannot see any differences which in my judgment 
to ate them. At the same time, Dentaliwm striolatum St. seems 
to me a perfectly distinct and good species.
