FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 95 



Color in alcohol. — Dorsal ground color smoke gray anteriorly, be- 

 coming drab-gray on posterior back and upper limb surfaces; a cream- 

 color dorsolateral line beginning behind the eyes, widening on the sides 

 and becoming indistinct in front of the groin, a slate-gray line edging 

 its lower border for most of its extent; another cream-color stripe be- 

 ginning below the eye, and covering the lower lip and extending onto 

 the axilla, where it merges with the ventral coloration; sides below 

 cream color; dorsolateral stripe smoke gray, with numerous round, 

 black dots in the groin, on anterior femur, on sides halfway to shoulder, 

 and in axilla; coarser black blotches on posterior femur; a few dark 

 spots on inner parts of tibia and foot and some small black dots below 

 the white glandular ridge at anterior anal border. Outer surface of 

 tibia with a wide white line, forearm with a very indistinct one. 

 Ventral surfaces pale olive-buff, immaculate. 



Variations. — ^The largest example, USNM 96798, a female from 

 Alto da Serra, measures 56 mm. in head and body length. This one 

 and two others from the same locality resemble BM 85.9.7.23 very 

 closely in details of structure and in coloration, except that the ante- 

 rior surface of the femur is less heavUy spotted with black in the 

 former specimens, while the concealed inner surface of the tibia is 

 also less darkly pigmented. In the smallest of the Alto da Serra frogs, 

 as well as in USNM 97212, from Sao Francisco de Paula, the snout 

 is more pointed at the tip than is that of the described specimen. 

 This character is of notable variability in many other species. 



Remarks. — The name Hyia pulchella for the Argentine and Uruguay 

 frogs is apparently correctly synonymized with H. raddiana by 

 Nieden. None of the specimens in the U. S. National Museum pre- 

 viously identified as pulchella can be distinguished in any way from 

 the tjrpical raddiana specimens. 



Much more distiuct, however, is H. raddiana andina Mertens, be- 

 cause of its apparently larger head and its quite different color pattern. 

 Since this form is not known to occur in Brazil, a discussion of it is 

 not included here. The males of andina have the )(-shaped skinfolds 

 at the sides of the throat very well developed, and as few other frogs 

 except raddiana show this characteristic, it is evident that the forms 

 are allied.
