 The seventh pair of legs have the thigh rounded ; the

 but the anterior margin is armed with a few stout spines; 

 the finger is crooked, and furnished with three bead-like 

 tubercles on the anterior margin. The antepenultimate 

 pair of caudal appendages have the branches very short, 

 unequal in length, and styliform. The penultimate pair 

 have the branches short, subequal, styliform, and free 

 from hairs. The ultimate pair have the branches long, 

 subequal, and plentifully furnished with plumose hairs. 

 The central tail-piece has the approximate margin of 

 each division nearly straight, and the external convex,

We have received this species from the Moray Frith, 

 where it was procured by Mr. Gregor, of MacdufF, from 

 the stomach of a haddock captured in about thirty 

 fathoms of water : also from Mr. Edward, of Banff, and 

 the Rev. Geo. Gordon, of Elgin. It has also been sent 

 to us from Cumbrae, where it was taken by Mr. D. 

 Robertson ; and our lamented friend, the late Mr. Barlee, 

 dredged it off the Shetlands.
