9i Rev. A. M. Norman on sojne Crustacea 



from a specimen sent for examination by Mr. T. Edward* 

 from Banff in August 1863 ; a second British specimen has 

 now (March 1886) been taken bj the Fishery Board at 

 Tarbert, Loch Fyne. 



On the Norwegian coast it has been found in the Har- 

 danger and Christiania Fiords and at Aalesund. 



Mysidopsis angusta has a very narrow, lanceolate antennal 

 scale, which is ciliated all round, and is about twice the length 

 of the peduncle of the antennules. The telson is cleft at the 

 apex, and the sides of the cleft are quite plain, that is, without 

 any teeth or serration within the cleft, and by this character 

 the species may be distinguished not only from the other 

 species of ALysidopsis^ but i'rom all Mysidea which have as 

 yet been described.

Although not hitherto recorded as occurring in our seas, 

 Leptomysis lingvura was found by me twenty-six years ago 

 in great abundance at Howden, County Durham, and shortly 

 afterwards at Seaham Harbour. It remained with a MS. 

 name in my collection until it was described by Prof. G. O. 

 Sars. In 1883 it was sent to me by Mr. C. Parker from 

 Starcross, Devon, and last year one or two specimens were 

 forwarded to me for determination from Tarbert, Loch Fyne, 

 by the Scotch Fishery Board. It would thus seem that the 

 species is widely distributed round our coast.

Specimens of this species are in my collection from the

 Smiles's ' Life of a Scotch Naturalist,' " Mysis mixta.''' It is much to be 

 regretted that that list should have been published without revision.
