FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 31 



orbital diameter about twice the width of upper eyelid, three times the 

 interval between nostrils. Tympanum not distinct in outline, ap- 

 parently higher than broad, as high as the diam^eter of the eye and 

 very close to it. Fingers free, with lateral ridges distally, first and 

 second fingers subequal and shorter than fourth; a large palmar 

 tubercle, and a smaller one beside it at base of first finger; subarticular 

 tubercles of fingers quite prominent, some double and some single; 

 toes webbed at the base, with a lateral series of minute tubercles, 

 third and fifth subequal, reaching to base of penultimate phalanx of 

 fourth; a small oval inner and a round outer metatarsal tubercle; no 

 tarsal ridge; subarticular tubercles of toes small, all single. Body 

 stout, in postaxillary region nearly twice the greatest width of head 

 (in female distended with eggs) ; when hind leg is adpressed, heel fails 

 to reach axilla, and tip of fourth toe barely reaches end of snout; 

 when limbs are laid along the sides, knee and elbow are separated by 

 an interval equal to length of tibia; when hind legs are bent at right 

 angles to body, heels are sidely separated. Body completely covered 

 with small tubercles, slightly larger along the dorsolateral line and 

 around anus, smaller on sides and on lower sm-face of legs. No ob- 

 vious scapular ridges; no tibial gland; no skinfold on chest. A pair of 

 very prominent tubercles just over the anus. 



Dimensions. — Head and body 59 mm.; head length 16 mm., width 

 20 mm.; femur 22 mm.; tibia 19 mm.; foot 20 mm.; hand 14 mm. 



Color in alcohol. — Dorsum deep fawn color; a row of four or five 

 black ocelli surrounded by a pale border on each side of the midline, 

 other ocelli nearer the dorsolateral region; legs and arms with black 

 crossbands separated by light areas ; a narrow, median, light line from 

 snout to anus; ventral region with a coarse dark and light reticulation, 

 center of throat dusky, edges of lips fawn color; warts along lateral line 

 and below anus light, evidently orange or red in life. 



Variations. — A smaller individual, IB 398, agrees in all essential 

 characteristics with the specimen just described. 



Remarks. — This species is apparently not closely related to any 

 other Brazilian form, although superficially it somewhat resembles 

 B. granulosus and B. g. d'orbignyi in stoutness of body and in Hmb 

 proportions. Its characteristic pattern distinguishes it at once from 

 all other Brazilian toads. In shape of parotoids it suggests B. 

 marmoreus of Mexico. The inclusion of this species in the synonymy 

 of B. typhonius is entirely unjustified.
