 scribed at page 251, is an addition to the British fauna.

Loch of Whatley. 



In the Loch of Whatley animal life, though moderately common, was 

 not so varied as in Loch of Cliff, but among the organisms obtained there 

 were one or two rather rare things, as for example : — Ophiocamptus sarsi, 

 Mrazek ; Attheyella pygmsea (G. 0. Sars.) ; and Chydorus globosus, Baird. 

 Mollusca were apparently very scarce. Diatoms in great variety and 

 abundance were observed in the gathering from this loch.
