ANONYX LONGIPES.

third, all the joints are long. The wrists and the feet 
are subequal. The feet are furnished, upon the flexible 
side, with a few fine hairs, and a stout, sharp, short 
spine, curved reversely to the finger, which is long, 
slender, and appears capable of impinging against the 
front of the foot. The caudal appendages are subequal, 
the penultimate being slightly the shortest, and the 
branches of the last are unequal. The middle tail- 
piece is longer than the peduncle of the last pair of 
caudal appendages. 
This species was sent to us by our valued corres- 
pondent, Mr. Barlee, who dredged it on the Haaf Fish- 
ing-ground, about thirty miles off the Shetland Islands, 
where it has also been taken by the Rev. A. M. Norman 
and Mr. Jeffreys. Without examination it may be mis- 
taken for Lysianassa marina , (from which it chiefly differs 
in the generic distinction,) as well as for Anonyx lagena 
of Kroyer ; but the peculiar form of the eye in the latter, 
which is tolerably large, and formed like an inverted 
comma, will offer a ready means of distinction, besides 
other, perhaps more important but less striking charac- 
ters. From A. ampulla it is distinguishable by the length 
of the inferior antennae. 
Our figure of this species is taken from a female spe- 
cimen.
