FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 149 



and chest with minute scattered pustules, that of belly coarsely granular on the 

 breast, finely granular posteriorly and on the lower surface of femur; a slight skin 

 fold across the chest and another raueh more prominent preceding it across the 

 throat. A series of lateral folds on each side of the throat marking the presence 

 of lateral gular sacs in the male. 



Dimensions: Head and body, 35 mm; head length, 11.5 mm; diameter of eye, 

 4 mm; width of head, 11 mm; femur, 15 mm; tibia, 16.5 mm; hind limb, 48 mm; 

 forelimb, 19 mm^; foot, 14 mm; hand, 9 mm. 



Color in alcohol: Dorsal ground color ecru-drab, with an indistinct light 

 sepia triangle between the eyes; a dorsolateral longitudinal series of very irregular 

 sepia spots sometimes anastomosing across the back, their outer margin dark 

 and fairly straight, delineating a dorsolateral stripe of the pale ground color, this 

 light stripe edged below with an Indefinite dark stripe, which begins behind the 

 tympanum and breaks up on the sides into a fine reticulation of dark on a light 

 ground, continued and becoming coarser toward the groin; a faint dark line along 

 canthus rostralis; loreal region and upper lip marbled slightly with drab; upper 

 surface of femur with fine sepia reticulations fading out on the anterior surface, 

 becoming darker and coarser on the posterior surface and enclosing irregular pale 

 cinnamon areas; upper surface of tibia with three large diagonal spots; outer 

 tarsus and upper arm indistinctly marbled with drab; ventral surface immaculate 

 buff. 



Color in life: Some color notes on living specimens from Manguinhos were 

 made on January 18, 1935. U. S. N. M. no. 97374: Malachite to sage green above, 

 immaculate. Posterior femur chrome-yellow with brown reticulations. Throat 

 citron-yellow; belly sulphur-yellow in the center, chrome-yellow toward the sides, 

 immaculate. U. S. N. M. no. 97376: Dorsum clay color in center, with a drab 

 dorsolateral stripe. Groin and ventral surface olive-buff, the sides with sepia 

 spots. Fore and hind legs ochraceous, barred with raw umber. U. S. N. M. no. 

 97375: Dorsum light ohve-gray, with coarse mouse-gray blotches edged with 

 black. Upper and posterior parts of femur orange-ochraceous, mottled with dark 

 sepia. Chin, chest, and lower parts of limbs ecru-drab; belly pale blue. 



Variations: Within the usual limits there is the same amount of confusing 

 variation in this species that is met with in the other members of the rubra group. 

 The snout is usually rounded, but in about one-third of the examples it is slightly 

 pointed. The tympanum, always distinct, may range from one-half to two- 

 thirds the diameter of the eye in width. The interorbital diameter is often Iji 

 times the width of the upper eyehd, but in a few instances scarcely exceeds the 

 eyelid in width. The distance from the posterior border of the tympanum to the 

 tip of the snout varies between 31 and 36 percent of the total length of head and 

 body, while the tibia is from 43 to 54 percent of this length. The adpressed heel 

 may reach occasionally only to the posterior corner of the eye, most often to the 

 center or anterior border of the eye, and rarely as far as the nostril. The disks of 

 the fingers may be large, moderate or rather small, and as the tympanum itself 

 varies considerably in size, the fourth finger disk may cover as little as one-fourth 

 of its area to as much as two-thirds. The skin of the back is smooth in perhaps 

 one-fourth of the specimens (this may depend on preservation to some extent), 

 faintly granular all over in some, granular only on the posterior part in others. 



The pattern seems as varied as do the physical dimensions. Usually there is a 

 more or less distinct dark area between the eyes, but no other markings are at all 

 constant. Some individuals are pale drab, with remnants of longitudinal dark 

 stripes as in rubra appearing in this species as two rather irregular dark stripes 

 enclosing a light area on each side of the back. In other specimens the upper 

 one of the two dark stripes shortens and becomes crescentic; in many cases its
