FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 75 



Dimensions. — Head and body 86 mm.; head length 27 mm., width 

 27 mm.; femur 41 mm.; tibia 46 mm.; foot 35 mm.; hand 26.5 mm. 



Color in alcohol. — Dorsal ground color cream -buff; a very irregular 

 wide russet blotch across the occiput and extending forward onto the 

 eyelids, another across the lumbar region, both outlined with smaller 

 black spots irregularl}'" arranged; tip of snout with russet and black 

 markings; fem.ur with two narrow dark crossbars on its upper surface 

 only, a similar bar on knee, two other crescent-shaped bars on upper 

 tibial surface, and four or five others on tarsus and foot; posterior 

 femur immaculate pale drab; venter pale cream, immaculate; upper 

 lip pale russet, -wdth some small dark spots along its margin ; glandular 

 ridge around tj^mpanum edged with black; a black, wing-shaped pre- 

 anal spot, and a network of fine black lines between the postanal 

 tubercles; postanal "flaps" pale cream color. 



Variations. — The additional specimens belonging to the Institute 

 Butantan agree extremely well in all essentials with the one just 

 described. The smallest, IB 58, measuring 65 mm. in length, has the 

 most pronounced postanal "flaps"; these are 2 mm. long and 5 mm. 

 wide, extending well beyond the end of the body. The heel may 

 extend to between nostril and tip of snout or considerably beyond 

 the snout. The head width is equal to its length in all but one in- 

 dividual, where it is wider than long. The snout is half the length 

 of the head. The tibia is from 50.7 to 55.0 percent of the total 

 length, averaging 53.4. The irregular patches across head and 

 lumbar region are less evident in some than in others, but the number 

 of dark femoral bars is the same in these six specimens. 



Remarks. — The type of H. langsdorfi, MNHP 4634, measures 

 93 mm. in head and body length. USNM 121337 was carefully 

 compared with it. The two specimens were found to resemble 

 each other very closely, as the type still plainly shov/s the many small 

 tubercles on the back, the bony head, the long legs with squarish 

 dark spots, and the dark reticulations around the anus.
