 (S.F.B.). 

 Mysis spiritus, Norman.

 specimens (S.F.B.). 



[Also taken by tow-net at 14 fathoms near Aberdeen, 

 October 1886 (S.F.B.).]

 Mysis lamorncB, R. Q. Couch* 



Mysis lamornce, White, Pop. Hist. Brit. Crust., p. 143, 1857. 

 Mysis aurantia, G. 0. Sars, Beretrung om en i Sommeren, 1863, 

 foretagen Zoologisk Reise, p. 30. Also taken in surface-net 

 off Bo'ness ; two or three specimens (S.F.B.). 

 Mysis vulgaris, J. Vaughan Thompson. 



Mysis vulgaris, Bell, Brit. Stalk-eyed Crust, p. 339, 1853. A 

 common species in surface-net, material in various parts of 

 the Forth west of Queensferry, and occasionally in Granton 

 Harbour (S.F.B.). 



Remarks. — With the exception of the last, the species of Mysis re- 

 corded here have the telson more or less bifurcate, but the telson of 

 Mysis vulgaris terminates in a blunt point, and the antennal scales also 

 differ from those of the other species of the genus. Cynthia flemingii 

 (Goodsir), Themisto longispinosa (Goodsir), and Themisto brevispinosa 

 (Goodsir), recorded from the Firth of Forth by Mr H. Goodsir, are 

 doubtful species. Dr Norman says that it is impossible to identify 

 Goodsir's Mysidae, but suggests that his Cynthia flemingii may be the 

 Siriella crassipes of G. 0. Sars, and Themisto longispinosa and Themisto 

 brevispinosa the males of species of Mysis. 



Through the investigations carried on by the Fishery Board, nine 

 species of Schizopoda have been added to the fauna of the Firth of Forth. 

 It may be worth noting that though a considerable number of species of 

 Schizopods are now included in the British fauna, only two (Nyctiphanes 

 norvegica and Boreophausia raschii) have been observed among the con- 

 tents of fishes' stomachs, e.g., those of the herring and mackerel.
