FROGS OF SOUTHEASTERN BRAZIL COCHRAN 253 



above it behind the eye; ventral surface quite smooth. A slight 

 wrinkling of throat skin may indicate the presence of a small external 

 vocal sac; upper arm and forearm very well developed. 



Dimensions. — Head and body 27 mm.; head length 9 mm., width 

 9.5 mm.; femur 12 mm.; tibia 12.5 mm.; foot 12 mm.; hand 7 mm. 



Color in alcohol. — Dorsum light fawn color, with a few small darker 

 spots scattered over back; upper lip immaculate cream, except for a 

 dark spot on anterior border of tympanum; femur with two or three 

 faint darker crossbars, extending onto tibia and foot; throat pale 

 cream with fine darker reticulations; rest of ventral surface pale. 



Remarks. — This form is well separated geographically from the 

 three others, but is closely allied to all of them nevertheless. It has 

 a broad and rounded snout, in this feature suggesting its relationship 

 to dispar and aeneus; its highly reticulated throat again suggests dispar, 

 while separating it from aeneus and gaudichaudii. The difference 

 in sex in trachystoma is not marked, and the general form of the body 

 seems more slender than in dispar.

The city of Rio de Janeiro was the type locality for specimens on 

 which two much-disputed specific names have been based, Stein- 

 dachner's Telmatohius brasiliensis and Cope's Grypiscus umhrinus.
