anfcenniiles. 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 Mysidopsis^ but from all Mysidea which have as yet been 

 described.

Although not hitherto recorded as occurring in our seas, Leptomysis 

 Ungvura 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 

 Professor G. 0. 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.

This small species, described from the Mediterranean, was added to 

 the British fauna by Mr C. Parker, who found specimens in 1884 at 

 Starcross Devon, which he forwarded to me ; and specimens have now 

 been taken at Tarbert Loch Fyne, by the Scotch Fishery Laboratory.
