glandular knob behind the mouth; lower lip with pale broken ocelli on 

 a plumbeous ground; entire chin and throat dark plumbeous with nu- 

 merous small round buff spots; remainder of ventral region buff, 

 with slight dusky marblings on chest and sides of abdomen, and 

 darker mottlings below tibia and foot. 



Color in life. — From the published figure of the type (Lutz, 1926): 

 Dorsum light burnt umber; a wide chocolate dorsolateral stripe, the 

 sides below this tawny-olive to wax yellow with darker spots; legs 

 reddish chocolate with maroon spots and crossbars, toes and fingers 

 lightening to drab. Chin and throat dull sepia with small yellow spots ; 

 ventral surface mottled white and gamboge yellow, very intense across 

 abdomen and on lower femur, the yellow mottling gradually obscured 

 by dull sepia on forearm and tibia ; palms of hands nearly uniform sepia. 



Remarks. — No specimen other than this one has been collected at 

 the type locality. It was found by Zikan under stones, on the edge of 

 a lake, a habitat like that of L. ocellatus and L. pentadactylus penta- 

 dactylus Laurenti. The voice of the male is unrecorded. 



In examining adult examples of typical pentadactylus from British 

 Guiana and Costa Rica, I have noted that in smoothness of skin and 

 in color pattern these specimens closely upprosich. Jlavopictus . Only a 

 large series of the latter can make it possible to verify this resem- 

 blance. On the type oi flavopictus the lateral and postfemoral glands 

 stand out far more than on any specimen of pentadactylus compared 

 with it (for example, USNM 109148, Maranguape, Ceard, and USNM 

 109144, Campina Grande, Paraiba), and this condition alone distin- 

 guishes it from pentadactylus, which has a narrow dorsolateral gland 

 and at most a few small scattered glands on the sides. 



In a comparison of the type of flavopictus with an example of 

 labyrinthicus (USNM 121286) nearly the same size, the following 

 differences were noted:
