Preliminary List of Deep Water Crustacea in Green Lake, 



Wis., U. S. A. 



By C. Dwight Marsh, Ripon- College, Ripon. 



During the past season I made a large number of collections from 

 the deep water of Green Lake , and while I wish to postpone a detai- 

 led statement of the results until after further collections and study, 

 I think a preliminary list of the Crustacea would be of interest to those 

 making similar investigations. 



The collections were made between the' months of August and 

 November, inclusive, and in water between 17 and 49 meters in depth. 

 The list is as follows : 



Diaptomus sicilis Forbes. 



Diaptomus minutus Lillj. 



Epischura lacustris Forbes. 



Limnocalanus macrurus Sars. 



Cyclops fiwoiatilis Herrick . 



Cyclops Thomasi Forbes. 



Cyclops sp. 



Cypris sp. 



Daphnella brachyura Lievin. 



Daphnia kahlbergensis Schoedler. 



Bosmina sp. nov. 



Leptodora hyalina Lillj. 



Pontoporeia Hoyi Smith. 



My sis relicta Loven. 

 The new Bosmina will be described by Dr. O. E. Imhof. 

 Diaptomus minutus Lillj. has not, to my knowledge, been found, 

 hitherto, except in Newfoundland.
