FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 91 



of small drab dots, outer limb surfaces with a wider sepia stripe; pos- 

 terior surface of thigh immaculate; anal region sepia, with a light hori- 

 zontal line above it; upper lips and also sides of chin with narrow drab 

 longitudinal lines; remainder of ventral surface immaculate cream 

 buff. 



Color in life. — From sketch by Pugas of specimen from Itatiaia, Rio 

 de Janeiro. Dorsal ground color cream ; a vandyke-brown me dian 

 dorsal stripe beginning on top of snout and continuing to anus; 

 another brown stripe beginning on the eyelid and paralleling the 

 median one almost to the anus; a brown lateral stripe beginning on the 

 tip of the snout, widening on the loreal region, and continuing on the 

 sides to the groin; a number of small brown dots in linear arrangement 

 on the light areas of the posterior back, and som.e small light dots 

 within the brown stripes; anterior and posterior surface of femm- 

 ochraceous-buff, with a definite cream-color stripe running along its 

 upper surface; forearm and tibia striped with russet on outer and 

 inner surfaces, cream above, with a series of minute brown dots along 

 the cream stripe on the tibia; inside of tarsus and foot pale rufous, the 

 outer parts including webs and disks cream color; a narrow wavy 

 brown line edging anus in front. Iris saffron yellow, with fine black 

 reticulations; pupil black, transversely elliptic. 



Variations. — Among 17 half-gro^vn and adult frogs from Bonito, 

 Serra da Bocaina, some variation is to be seen in the length of the 

 snout, as it is sometimes longer than the eye diameter in the larger 

 females. While the heel reaches to the anterior border of the eye 

 and often to tip of snout, in the large male, USNM 81126, it reaches 

 barely to the center of the eye. The webbing between the fingers 

 is often slight, but sometimes extends to nearly one-third their length. 

 The heel ridge may sometimes develop into a rather blunt tubercle. 

 The vomerine teeth, always heavy and distinct, may be between the 

 posterior borders of the choanae, or slightly behind this level. The 

 tympanum shows the usual variation found in most other species of 

 frogs, sometimes a little more than one-half the eye diameter, occa- 

 sionally a Httle less. 



The greatest variation, however, comes in the color pattern, since 

 it changes as the frog grows. In the youngest individuals, including 

 those just metamorphosed, are three dorsal stripes of varying widths 

 and intensities, sometimes continuous from the head to just above 

 the anus and sometimes broken up into a series of beadhke spots. 

 Between these three main stripes are usually finer stripes or series of 

 elongate dots, darker and more prominent in the posterior region. 

 There is also a wide, dark, lateral stripe going from the nostril to the 

 groin, and below it a shorter, narrower stripe from the comer of the
