FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 183 



not appear to vary so much. The type of Centrotelma cryptomelan, 

 MCZ 1530, has the fingers two-thirds webbed, hence the webs are 

 larger than m the one described. 



The pattern is not identical in four individuals, from Colomi, near 

 Teresdpolis, in which it is still retained. One, USNM 97720, differs 

 from the described specimen in having a dark brown arrow-shaped 

 marking in the center of the back, with a diagonal brown line from the 

 anteriorly pointing tip of the arrow to the posterior upper eyelid. 

 Across the sacral region is a brown band invaded on one side by irreg- 

 ular dark-edged white spots. The femur has about a dozen black, 

 wavy, parallel lines on its anterior and posterior surface, these being 

 much more definite than on any of the other specimens. This one 

 lacks the dark median stripe on top of the head. A smaller frog, 

 USNM 97722, is practically without pattern of any kind, except for 

 some faint cloudy marblings on the sides, and a trace of a dark sufi^usion 

 along posterior side of femur. 



Remarks. — The frogs from Colomi were kept alive for some time. 

 They were very sluggish by day, and when handled would assume a 

 wooden, dead appearance, with the limbs brought close to the body 

 and the head bent forward, so that they resembled an old fungus or 

 chip of wood. They could be left on their backs for a long time in this 

 condition, and would continue to play dead even when undisturbed. 

 At night they climbed slowly around the plants in the vivarium, but 

 were not seen to take food, though ants' eggs and various kinds of 

 insect larvae were offered. The time of year (April and May) may 

 have had something to do with their refusal of food and general slug- 

 gishness, as it was then the beginning of winter. 



The adequate discussions of this perplexing subspecies by Parker 

 (1933, p. 10; 1935, p. 512), have defined its status quite clearly. While 

 it is notably subject to great variation in color and even in limb pro- 

 portion, the very thin legs and arms, the heel tubercle, and the promi- 

 nent angular head make it a relatively easy form to identify.
