mm. long. These specimens are marbled drab to sepia in general tone ; 

 one shows wide light dorsolateral stripes, one has merely the suggestion 

 of a light dorsolateral line, while the third is without any light marking 

 in that region. The upper lip has three or four light diagonal stripes 

 separating the dark area into irregular triangles, and the extreme tip 

 of the snout is marked with a vertical light spot, while the edge of the 

 lower lip is more or less distinctly dotted with white. A hemispherical 

 lighter spot is dimly perceptible in front of the slightly darker inter- 

 orbital bar. A dark anal patch is present; in one of the specimens a 

 light sacral median line runs to the anus and branches below it into 

 two postfemoral lines which widen and become irregular before fading 

 out under the knee. A narrow light line, bordered by a dark one, 

 crosses the heel, bordering the darker area under the tarsus. The chin 

 and chest are clouded with gray dots, while the lower surfaces of the 

 legs are sprinkled with small sepia spots. 



The structure and proportions seem fairly constant in this species. 

 The heel of the adpressed hind leg always reaches well beyond the snout 

 tip, the tibia alone measuring between two-thirds and three-fourths of 

 the length of head and body. The eye, while by no means small, is 

 only about two- thirds the length of the snout, the extension of the 

 snout apparently having taken place at the extreme tip. One of the 

 topo types, USNM 97761, has a very small tympanum, less than half 

 the eye diameter, and consequently the disk of the third toe very 

 nearly covers it. The tongue of this specimen is narrow, and oval 

 and thick at the tip, whereas those of the other adults are spreading 

 and thinner at the tip. 



Remarks. — Although most Brazilian species of Eleutherodaciylus live 

 on the ground under leaves, the original series of seven cotypes, four 

 of which are now in the Instituto Oswaldo Cruz, was collected among 

 the leaves of a tree six feet from the ground at night. They were not 

 difficult to catch, as they were not very active in spite of their long legs. 

 The call is a pr-r-r-r-r-r-r, the last very sharply staccato and ending 

 quickly, the first trilled.
