Mysis inermis, Rathke. 
Mysis imermis, G. O. Sars, ops cit., Hefte iii. p. 54, pl. xxvii., 
1879. Taken by surface-net off Bo’ness, November 1887 
(S.F.B.). 
Mysis spiritus, Norman. 
Mysis spiritus, G. O. Sars, op. cit., Hefte iii. p. 58, pl. xxviii., 
1879. Taken in the same locality as the last; several 
specimens (S.F.B.). 
[Also taken by tow-net at 14 fathoms near Aberdeen, 
October 1886 (S.F.B.).] 
Mysis ornata, G. O. Sars. 
Mysis ornata, G. O. Sars, op. cit., Hefte iii. p, 62, pl. xxix., 1879. 
Taken with the last two (S.F.B.). 
Mysis lamorne, R. Q. Couch. 
Mysis lamorne, White, Pop. Hist. Brit. Crust., p. 143, 1857. 
Mysis aurantia, G. O. 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 (8S. 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 flemingti 
(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 Mysidx, but suggests that his Cynthia flemingit may be the 
Striella crassipes of G. O. Sars, and Themisto longispinosa and Themisto 
brevispinosa the males of species of Mysvs. 
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 (Wyctiphanes 
norvegica and Boreophausia raschit) have been observed among the con- 
tents of fishes’ stomachs, e.g., those of the herring and mackerel.
