Hyla baudinii dolomedes, sp. nov. 



Type: M. C. Z. 2,39, from the Rio Esnape, Sambu Valley, 

 eastern Panama. Barbour and Brooks, 1922. 



Similar to true H. baudinii of Central America, but with 

 very long hind limbs — longer than Central American individ- 

 uals which I have seen. The tibio-tarsal articulation reaches 

 well beyond the tip of the snout. 



Boulenger (P. Z. S., 1913, p. 1,023) remarks: "One of 

 the specimens (from the Colombian Choco), a female, is 

 remarkable for the longer hind limbs, the tibio-tarsal articu- 

 lation reaching beyond the tip of the snout." We are not 

 informed whether the other individuals may not also have 

 had limbs longer than normal, if less strikingly so. In any 

 case, such frogs seem unknown in upper middle America, and 

 even if there is overlapping as well as possible intergradation 

 between the form it is worthy of a name for convenience. The 

 form is probably worth full specific recognition. 



The fourth species found, I believe, represents Dr. Noble's 

 Hyla chic a. The three examples taken agree fairly well with 

 a para type of chica, which seems to have a vastly greater 

 range than one would expect for such a tiny form. 



The species of Atelopus are at best but half known. Ate- 

 lopus varius as now understood has a very great range, and 

 wherever it has been collected in numbers it appears to vary 

 greatly both individually and geographically. 



This spring we camped for a week or more by a small 

 stream, one of the headwaters of the Rio San Antonio on the 

 slopes of Mt. Sapo. Little frogs of the genus Atelopus were 

 common and we observed them daily. Singularly lethargic, 

 they were usually perched on some projecting stone in mid- 

 stream, and when disturbed they flopped feebly into the
