FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 65 



on the inner base of the thumb, measures only 62 mm. in length. 

 These two are a uniform, dark seal brown above, without any traces 

 of the rectangular dorsal marking set off by a drab bordering area 

 which characterizes both of the Minas Gerais specimens. The band- 

 ing on the thighs of the males is reduced to a few reticulations, but 

 the tibia in one of them shows some banding, although in this instance 

 the dark bands are narrower than the intervening light areas. 



Remarks.- — The two cotypes of Hyla zebra Dum^ril and Bibron, 

 MHNP 421, are soft and faded, but some vertical dark postfemoral 

 bars are still discernible. The skin on the head and body of the 

 larger specimen is tubercular; that of the smaller specimen is less so. 

 Both have a wide head like that of H. venulosa. Three cotypes of 

 H. fusca Daudin, MNHP 419-20, are likewise flabby and faded, but 

 the round snout like that of venulosa is still apparent. The toes are 

 two-thirds webbed, the fingers webbed only at the base. It seems 

 possible that the chestnut-colored type described by Daudin was a 

 venulosa with a uniform dorsal coloration, like that already mentioned 

 in regard to two specimens from Lower Amazonia. It seems probable, 

 therefore, that zebra and jusca should be made synonyms of venulosa.
