Crustacea and Mollusca new to the Fauna of the Forth, loo 



be ascribed to any known species. Through the investi- 

 gations carried on by the Fishery Board thirteen additional 

 species of Schizapods have been added to tlie Forth fauna. 

 Nine of these are recorded in the Board's lieport publislied 

 last year. Tlie species wliich I now exhibit Imve been 

 observed since that Ptcport was published. They are as 

 follows : — 



Mysiclopsis didelphys, Norman. 



Mysis didelphys, Norman, Dredging Report, Trans. Tyne Nat. F. Clul), vol. 



v., p. 270, pi. xii., figs. 9-12. 

 Mysido])sis didelphys, G. 0. S;irs, Mon. over de ved Nor. Kyster forekoni- 



mende Mysider, part ii., \). 20, pi. vii. (1872). 



This appears to be a rare species in the Forth. I observed 

 it anion o- some tow-net material collected near Fidra duriuff 

 November last. 



Erythro]ps goesii, G. 0. Sars, — new to Britain. 



Ml/sis erythrophthalma. Goes, Crust. Decap. mar. Svec. , p. 18. 

 Erythrops goesii, G. 0. Sars, Mon. over de ved Nor. Kyster forekommende 

 Mysider, part i., p. 24, pi. i. (1870). 



I iind this species frequent all over the Forth from Inch- 

 keith to the May Island, as w^ell as outside the May. How 

 it happens to have escaped observation hitherto may not be 

 easily explained. Another species, F. loygmxa, G. 0. Sars, 

 which I first observed in East Loch Tarbert, Locii Fyne, was 

 also new to Britain. A third species, E. serratus, G. O. Sars, 

 was discovered by Dr A. M. Norman among the Shetland 

 Islands. They are all small, but easily recognised, when 

 living, by their bright red eyes. The eyes turn whitish 

 after being kept in spirit awdiile. 



Lcptomysis gracilis, G. 0. Sars. 



Mysidopsis hispida, Norman, Eeport Brit. Assoc, for the Advancement of 



Science, 1868, p. 267. 

 Lcptomysis gracilis, G. 0. Sars, Mon. over de ved Nor. Kyster forekommende 



Mysider, part iii., p. 31, jils. xix., xx (1879). 



Several specimens of this species have been observed 

 among tow-net material collected to tlie east of Inchkeith. 

 Previous Scotch records for it are the Moray Firth and tlie 

 Shetland Islands.
