ANONYX LONGIPES. 115 



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.
