ZOOLOGICAL NOTES. 

 Hekbert Osborn. 



Cedar Point offers a number of rather peculiar features for study, 

 and the fauna of the locality presents a very attractive field. On 

 the one hand there is an extensive beach some six or seven miles in 

 length, from which the sand dune formation extends backwards and 

 merges into a swampy area bordering the waters of Sandusky Bay. 

 On the beach after every storm will be found a large mass of drift 

 material, including numerous fishes that have been thrown ashore. 

 These furnish an attraction for a number of forms of animals, a 

 complete census of which has as yet not been attempted. It may be 

 mentioned, however, that numerous species of flies take to them to 

 deposit their eggs, the larvae a few days after each storm being a 

 conspicuous element to be followed a few days later by pupae or 

 mature flies; these in turn attract various birds and large numbers of

toads, which seem to secure a very constant source of food especially 

 in this vicinity. Species of burrowing Hymenoptera are conspicuous 

 and upon the sand dunes the grass hopper {Trimeroptropis maritima) 

 is especially abundant. A millipede (Fonfaria indianae) is also very 

 abundant crawling over the sand, and turtles from the lake pass up 

 the beach and over the dunes to deposit their eggs at favorable 

 points. 



Foot Prints. — A study of the tracks and foot prints which are 

 made in the sand is especially interesting, and the determination of
