second segment of the body. The hand is ovate, the 
palm straight, and defined by a small denticle. 
We have received this species from Guernsey, where 
it was taken by the Rev. A. M. Norman, and from Mill- 
port, N.B., where it was captured by Mr. Robertson. 
A considerable number were found by Mr. T. L. Couch 
in the crevices of a crab-pot buoy thrown. on the coast at 
Polperro during a heavy gale in 1854, and Mr. R. Q. 
Couch obtained the female at Mount’s Bay, in Gwavas 
Lake, and off St. Michael’s Mount, among confervee. 
Specimens from the Frith of Forth are contained in the 
British Museum Collection. 
In the male of this species the form of the palm is 
very liable to vary from the character as exhibited in the 
female to that of the male, as above described. 
It is not hastily that we have come to the conclusion 
that the two animals represented above are but sexes of 
one species. The animals are from the same locality, and 
their distinctive characters do not appear to have a 
higher value than such as indicate the sexes of one and 
the same species. We have been induced to identify it 
with Goodsir’s C, tuberculata by the pointed tooth upon 
the -head, rather than to associate the latter with C. 
hystrix (acuminifera), which also may possibly be but a 
variety of this same species.
