Shore habitat. Along the Galien River where it flows 

 through the Warren Woods are narrow shores of bare moist 

 mud or sand, in places attaining a width of five or ten feet. 

 Along the small streams flowing through the dune area at 

 Bridgman, Sawyer, and New Buffalo moist sandy shores also 

 occur. vSimilar shores of bare mud or sand are found around 

 small pools in the cleared ravines on the Warren Woods Pre'- 

 serve, and about the margins of the numerous ponds among 

 the dunes. A number of species were taken on the small wet, 

 sandy shores about the margins of spring pools and the streams 

 by which they discharge, on a marshy hillside near the Warren 

 Woods. 



In this habitat the following species were taken: 



Acrydium arenosum angustum* Tridactylus apicalis 



Paratettix cucullatus* BlUpes minuta* 



Gryllotalpa hexadactyla Nemobius fasciatus fasciatus 



Reed marsh habitat. Where the Galien River flows into 

 Lake Michigan at New Buffalo it broadens into a shallow, 

 vegetation-choked lagoon known as Lake Pottawattamie. 

 Around the margins of the south arm of this lagoon there is 

 a thick growth of Scirpus, mixed with Equisetum toward the 

 shore, enclosing which is a zone of sedges. On the lakeward 

 side the reeds stand in from several inches to a foot of water, 

 but near the shore the saturated sandy soil is exposed among
