FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 71 



between nostrils. Tympanum very distinct, large, about three- 

 fourths the diameter of the eye, separated from eye by an interval 

 equal to about two-thirds its own diameter. Fingers one-third 

 webbed, fourth much longer than second, reaching halfway upon 

 disk of third which covers about one- half the tympanic area (in the 

 male a pronoimced pollex near base of first finger ending in an inward- 

 curving, very sharp spur); toes slightly more than one-half webbed, 

 third and fifth subequal, disk of fourth covering one-third of the 

 tympanic area; a very pronounced oval inner but no outer metatarsal 

 tubercle; a well-marked, narrow ridge along inside of tarsus; no dermal 

 appendage on heel; body not elongate, rather massive, in postaxillary 

 region slightly less than greatest width of head; when hind leg is 

 adpressed, heel reaches considerably beyond snout; when limbs are 

 laid along the sides, knee and elbow overlap; when hind legs are bent 

 at right angles to the body, heels greatly overlap. Skin of upper parts 

 relatively smooth, but with many very narrow, long, glandular ridges 

 anastomosing over the back; a glandular ridge encircling upper border 

 of tympanum, narrow and faint above, becoming more prominent and 

 wider behind and terminating behind the jawbone; skin of throat and 

 chest very slightly granular, that of belly very coarsely granular, that 

 of posterior and lower side of femur also heavily granular; no apparent 

 skinfold across the chest. (Apparently a median external vocal sac 

 in the male.) 



Dimensions.— Hesid and body 87 mm.; head length 30 mm., width 

 34 mm.; femur 46 mm.; tibia 49 mm.; foot 35 mm.; hand 28 mm. 



Color in alcohol.— GTonnd color of upper parts pale drab, with fawn 

 color marblings on back and head ; a narrow sepia line originating on 

 the tip of the snout extending backwards and breaking up with spots 

 on the middle of the back; a narrow diagonal black Ime behind the 

 ear below the heavy posterior half of the glandular ridge; sides of body 

 with many vertical, narrow, drab bars; tibia with about ten alternately 

 wide and narrow olive crossbars; femur with similar but more widely 

 spaced bars; outer part of femur clove brown; anal region seal brown, 

 with a clove-brown line above it, preceded by a pale olive-gray area; 

 outer surface of foot from heel to toe-tips and of arm from elbow to 

 finger tips also seal brown, with a heavy border of clove brown ad- 

 joining a pale ohve-gray streak; ventral surface uniform pale olive- 

 gray except for some drab suffusions on under parts of limbs and on 

 chin. 



Color in life. — From a colored sketch by Sandig, without data. 

 Dorsal ground color dull cream with a pale sepia median dorsal stripe 

 and a few small sepia spots scattered irregularly on the back, upper 

 eyelids, and limbs; femur with about a dozen rather narrow di-ab-gray 

 bands on its upper and anterior surface; posteriorly these bands become
