Chorus Frog. 



Plate XXVII. (xi). 1-7. 

 Males. 



Pseudacris brachyphona 

 (Cope). 



Range: Southwestern Penn- 

 sylvania (Cope and Net- 

 ting), southeastern Ohio 

 (Walker), western Maryland 

 (Dunn), eastern Kentucky to 

 extreme south of West Vir- 

 ginia (P. C. Bibbee, R. K. 

 Brown and A. H. Wright). 



Habitat: Springy hillsides, 

 grassy pools, ditches, sources 

 and along upper courses of 

 upland rivulets, — more hilly 

 than lowland habitats. 



Size: Adults, 1-1 3/8 

 inches. (Males, 26-30 mm. 

 Females, 27-34 mm.). 



General appearance: These 

 are small frogs, gray or 

 brown in color, medium in 

 size for Pseudacris and with 

 the most distinct digital disks 

 of this genus. They are more 

 stocky in body and broader 

 in head than P. n. triseriata 

 and P. n.feriarum. The usual 

 mid-dorsal stripe or row of 

 spots is lacking. They often 

 have a light mid-dorsal area 

 somewhat after the pattern 

 of the cricket frog {Acris 

 gryllus). The interorbital tri- 

 angle is not white-edged be- 

 hind. The dorso-lateral bands 

 curve from the eye to mid- 

 back to groin, making two 

 crescents. They often meet 

 in mid-back to form a cross 

 or transverse bar. Sometimes 

 the pattern consists of a cross
