NORTH AMERICAN BATRACHIA AND REPTILIA. 23 



Since then, other specimens have been examined and carefully 

 compared with some from Florida and Texas. These have con- 

 vinced us that specific differences do not exist between them. By- 

 comparing the description with those above, it will be seen, 

 however, to differ as widel}^ from them as the}^ do from each 

 other; therefore, if they can be retained as subspecies, the 

 specimens falling under the following description will naturally 

 form a third subspecies for which we propose to retain the name 

 formerly used specifically, that is, circuLosa.

In the collection of the Smithsonian Institution, there are 

 specimens bearing the specific name of R. ai'eolata from Illinois 

 (2), Texas (1), Florida (1), and Georgia (1). Those from 

 Illinois, Florida, and Georgia have been labeled R. areolata 

 capita^ the other R. areolata areolata. The specimens from 

 Illinois (northern portion) are in coloration like the one we have 

 described above from Indiana, under the natne of R. areolata 

 clrculosa. The Texas specimen is white below, above light 

 brown with dark brown blotches, rounded on front portion of 

 body and encircled by a narrow whitish line, more angular 

 posteriorly; otherwise as in R. areolata circulosa. The Florida 

 specimen is white below and yellowish or greenish above, and 

 covered with rounded and more or less irregular brown spots;
