Acris crepitans Baird. 



We have not attempted as yet to separate all the puzzling Acris 

 into Acris gryllus and Acris crepitans. The authority who from loca- 

 tion, personal field experience, and from interest may possibly succeed 

 in accomplishing this task is Mr. Percy Viosca, Jr., of New Orleans. 



We spent June 10 and II, 1930 in the field with Mr. Viosca. Our 

 journal note of that date reads: Acris gryllus he calls a pine barren 

 Atlantic coastal form extending to the Florida parishes of Louisiana, 

 while Acris crepitans he holds a Mississippi valley or more western 

 form. Acris gryllus is a form of shade, A. crepitans an open water 

 form of water lily areas, water hyacinth fields, etc. A . crepitans has 

 two prominent white tubercles below vent. A. crepitans has shorter 

 snout than A. gryllus, more webbed fourth toe, and snout outline 

 different. Viosca holds their notes different and illustrated the differ- 

 ence with coins or stones and pointed out the two when calling, but 

 as yet we are not proficient enough to separate the two if we be apart 

 from him.
