FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 297 



between the posterior levels of the choanae and between their interior 

 margins. 



Remarks. — Very young specimens show the projecting upper jaw 

 and the gray chin and chest dotted with pearly white. They differ 

 considerably from four young E. petropolitanus, USNM 97437-40, 

 from Paineiras, which have the chin and throat immaculate white and 

 the snout rounded and not projecting. No immature examples of E. 

 miliaris under 38 mm. long were found to have the black spines on 

 the thumb, while petropolitanus has them well developed at 19 mm., 

 and E. lutzi at 25 mm., at least. 



This species is common in and near the city of Rio de Janeiro 

 wherever outcropping, vegetation-covered rocks are moistened by 

 springs. Some young ones were found under a mat of bromeliads 

 on rocks along the Avenida Niemeyer, the drive facing the sea front 

 to the west of the city. Others were found also within a few feet of 

 the ocean at Recreio dos Bandeirantes on granite rocks covered with 

 cactus and epiphytic plants. They are not averse to higher altitudes, 

 however, because one was caught inside a deserted gold mining tunnel 

 at Ouro PrSto in the mountains of Minas Gerais. 



In the catalog of the museum of the University of Copenhagen, 

 the type of Cystignathus discolor Reinhardt and Lutken had been 

 identified as Borborocoetes miliaris, an identification I confirmed in 

 1951 when I examined the remaining Reinhardt and Lutken material. 



In Vienna I examined Fitzinger's type of Eupsophus fuliginosus, 

 from Rio de Janeiro taken by the Novara Expedition, 1857-1859; it 

 appears to be a young E. miliari'?. 



MP 148, from Porto Cachoeiro, Espirito Santo, identified as 

 Ololigon abbreviatus petropolitana by Miranda-Ribeiro, is very defi- 

 nitely not Eupsophus petropolitanus, and it is apparent that no true 

 example of that species was known to Miranda-Ribeiro at the time of 

 his writing. This specimen from Espirito Santo does not differ in any 

 manner from the large scries of miliaris now at hand from the neigh- 

 boring State of Rio de Janeiro. 



Miranda-Ribeiro erected the name Ololigon abbreviatus taophora 

 for a form in which the color of the back is condensed in a T, its cross- 

 bars extending upon the upper eyelids and its staff generally being 

 interrupted in a regular series of quadrate spots between nape and 

 coccy^x. Its lateral roughness is also supposedly more evident. 



An example identified as 0. a. taophora by Ivliranda-Ribeiro, MP 

 432, collected in 1906, has completely lost its color, but one from the 

 same locahty, USNM 96812, collected in 1922 still retains its pattern. 

 It has the quadrate dorsal spots, the dark anterior bar between the 

 eyes, and some very coarse tubercles along the sides. It is likewise 

 entirely immaculate below, a condition not usually found in frogs
