FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 159 



nearly covers the tympanic area; no rudiment of a pollex; toes one- 

 half webbed, the fifth longer than third, disk of fourth covering about 

 three-fourths the tympanic area; an oval inner but no outer metatarsal 

 tubercle; apparently no tarsal ridge; no dermal heel appendage. 

 Body moderately elongate, in the postaxillary region much less than 

 greatest width of head; when hind leg is adpressed, heel reaches 

 between eye and nostril; when limbs are laid along the sides, knee and 

 elbow touch; when hind legs are bent at right angles to the body, 

 heels greatly overlap. Skin of upper parts with small tubercles which 

 are especially numerous between the eyes, on the temporal region and 

 in the middle of the back; between these tubercles the dorsal skin is 

 rather smooth; a faint granular fold encircling upper part of tympanum 

 and ending above shoulder; chin, chest, belly, and lower part of femur 

 very finely granulate; no apparent sldnfold across the chest. 



Dimensions. — Head and body 28 mm.; head length 10.5 mm., 

 width 9 mm.; femur 13 mm.; tibia 15.5 mm.; foot 11 mm.; hand 9 mm. 



Color in alcohol. — Dorsal surfaces pale wood brown, canthus rostraHs 

 with a dark line; upper lip with a dark spot in front of the eye; an 

 indistinct W-shaped dark mark between the eyes and a similar 

 larger one on occiput, especially pigmented at the bases of the small 

 tubercles; groin white, with irregular, large, clove-brown spots; femur 

 with wide seal-brown crossbars that run together on the posterior 

 part of femur to form an irregular longitudinal streak; tibia more 

 faintly crossbarred; ventral surfaces pale pinkish buff, the chin, 

 sides of belly, and anal region faintly spotted with russet. 



Color in life. — The following color notes were made from USNM 

 97747, taken from bulrushes in a marsh at Nova Friburgo: Iris pale 

 metallic wood brown above, ecru-drab below. Body color above 

 drab with hght olive reticulations across the middle of the back; a 

 seal-brown triangular marking between the eyes, its apex turned 

 backward, narrowly outlined with a metallic pale border. A seal- 

 brown dorsolateral stripe extending from posterior eye midway to 

 groin. A median and two lateral, sacral, seal-brown spots, rather 

 irregular in shape. Legs olive-buff on femora to buff on feet, with very 

 definite and distinct seal-brown crossbands. Ventral surface drab- 

 gray with a powdering of very uniform, minute, dark dots all over it. 

 This ventral pattern ceases very abruptly as the dorsal spotting 

 begins on the anterior femur and tibia on the sides, instead of blending 

 gradually, as is usually the case. 



Variations. — Although proportions, webbing, and other structural 

 characters appear to be more or less constant, there is considerable 

 variation in intensity of pattern. Some individuals are very light, 

 With, only a faint interocular bar and a few scattered pigmented areas 

 on the back, and a relatively faint crossbanding of the legs. Others
