FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 319 



These two authors (1936, p. 45) state that no geographic variation 

 was apparent in their 271 Gran Chaco examples, except for a con- 

 spicuous dark coloration in those from Sierra Cliica de Cordoba, 

 They were thus unable to render an opinion as to the status of 

 L. ocellatus macrosternum. 



The unique type of macrosternum is a young female, now greatly 

 faded, so that only a trace of the original pattern remains. It agrees 

 closely m structural details with the rather good series of freshly col- 

 lected ocellatus from Bahia and Minas Gerais, as well as with others 

 of similar age and sex from Rio de Janeiro. No valid character can 

 be found for separating the Bahian form, since the sternum of macro- 

 sternum is identical in size and shape with that of a Rio de Janeiran 

 specimen, USNM 97397, of the same dimensions. The proportions 

 of snout length, head width, and tibial length present the same degree 

 of variation in each locality. The development of the dorsal folds is 

 also the same in adults from Bahia and Rio de Janeiro. Some of the 

 Rio de Janeiran ocellatus have immaculate venters, although many are 

 spotted below. 



The dimensions of the type of macrosternum are: Head and body 

 68 nmi.; head length 23 mm., width, 22 mm.; tympanum 5 mm.; eye 

 8.5 mm.; interorbital width 3.5 mm.; foreleg from axilla ±36 mm.; 

 hind leg from vent 120 mm.; hind leg from groin 114 mm.; femur 

 34 mm. (soft) ; tibia 36 mm. ; foot from heel 57 mm.
