Small Loch of Uyasound. 



Neomysis vulgaris was obtained in this loch also, and associated with 

 the schizopod were numerous typical fresh-water organisms. As a matter 

 of fact the gathering from this small loch was a much richer gathering 

 than from some of the larger lochs on the same island ; and not only 

 were Crustacea numerous and varied, but other groups of organisms were 

 also well represented, such as Insect larvae, Tardijrrada, Rotifera, 

 Rhizopjda, Diatoms, &c. but no Mollusca were obtained in the gathering.
