The head is short, having a small rostrum . The eyes 
are situated upon an advanced lobe between the superior 
and inferior pairs of antennae. The superior antennae 
reach to the extremity of the penultimate joint of the 
peduncle of the inferior, which are about two-thirds of 
the length of the animal, very robust, and armed at 
the inferior distal extremity of the penultimate joint 
with two anteriorly-directed teeth, the outer one being 
the larger of the two. In other respects this species 
bears a near resemblance to C. Bonellii. 
We have only seen two specimens of this species, one 
dredged by Mr. Jeffreys off the Shetlands, and one re- 
cently obtained by the Rev. A. M. Norman in Outer 
Skerries Harbour, in from two to five fathoms of water, 
which we regard as identical with that of Bruze-
