OPPORTUNITIES FOR FAUNAL STUDIES AT THE 

 LAKE LABORATORY AT SANDUSKY.- 



Hhrbert Osborn. 



It is my desire to call attention to the rather exceptional oppor- 

 tunities for pursuing faunal studies in the vicinity of Sandusk}^ 

 which are made much more available b}- the location of a 

 summer laboratory or biological station at that point. The labor- 

 atory was located there by Professor Kellicott some years ago and 

 the wisdom of this selection has been amply demonstrated by the 

 wonderfully rich fauna which is found in the water and upon the 

 various areas of land in that vicinity. So far the work has not 

 been carried on so exhaustive!}^ as to complete the study of any- 

 one group of animals, although considerable progress has been 

 made in certain lines. Professor Kellicott' s studies were particu- 

 larly devoted to Rotifera, and in two or three papers on the 

 ' ' Rotifera of Sandusky Bay ' ' he presents the result of his col- 

 lecting in that group. The Protozoa have been studied during 

 the past year by Professor F. L. Landacre and his preliminary 

 report upon this group, showing 125 species, will indicate the 

 richness of the Protozoan fauna. The fishes have been collected 

 and probably most of the species are already recognized. The 

 study of the birds is considered as having been fairh- com- 

 plete. For U^e reptiles some work is being done and this 

 group will doubtless be worked up within a few years. Many 

 insects have been listed, over sixty species of Odonata having 

 been recognized so far, but doubtless other forms are to be found,
