a slight ridge along its inner margin. The toes are depressed like the 

 fingers, margined with a membranous fold, tapering, rounded upon 

 their extremities, and provided with small and conical, subarticulary 

 tubercles. The sole of the feet exhibits a few granules towards the 

 base of the toes. The metatarsal tubercles are comparatively small ; 

 the innermost being the largest. 



The skin is minutely granular above, on the head as well as on the 

 back ; beneath, it is nearly smooth, some obsolete granules being 

 occasionally seen. 



The ground color above is light-brown, clouded with reddish-brown, 

 and dotted with white along the dorsal region. There is a postocular, 

 chestnut-brown baud, extending beyond the shoulders. On the occi- 

 put may be seen a large, subtriangular, deep-brown patch stretching 

 over the posterior two-thirds of the eyelid. The legs are transversely 

 barred with reddish-brown. The inferior surface is unicolor, whitish 

 under the head and throat, greyish on the abdomen, and reddish on 

 the legs. The fingers and toes are yellowish. 



Specimens of this species were collected in the neighborhoods of 

 Valparaiso, Chile.
