Upon tlic deep-water fauna of a number of these lakes, and 

 upon Bavarian lakes at a lower elevation, I will report 

 hereafter. 



On the microscopic animals from high Alpine lakes of 

 Switzerland I have already published some statements with 

 regard to the following : — Engstlensee, Seealpsee, Cavloccio, 

 Lungino, and Sgrischus. The total number of lakes situated 

 in Switzerland above 600 metres and hitherto investigated 

 amounts to iifty-two. I give here in abstract the results 

 obtained in some of them. The greater part (forty-five) 

 belong to the Canton of the Grisons. Commencing with the
