FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 229 



between nostrils. Tympanum not visible. Fingers free, with a ser- 

 rated ridge down the sides of each one, their tips not dilated, first 

 slightly shorter than second, fourth longer than either; a pronounced 

 shovellike tubercle at base of first finger; all subarticular tubercles 

 well developed, the proximal ones showing a tendency to divide; a 

 granular ridge along outside of forearm ; no true axillar wing but skin 

 of body attached nearly to elbow; toes webbed at the base, not dilated, 

 with serrate dermal ridges, third a little longer than fifth and reaching 

 to base of antepenultimate phalanx on fourth; a large shovel-shaped 

 inner and a very small round outer metatarsal tubercle; a short ser- 

 rate tarsal ridge curving outside the shovel-shaped metatarsal tubercle, 

 and ending before it reaches the heel. Body very stout, in postaxil- 

 lary region slightly wider than the head ; when hind leg is adpressed, 

 heel barely reaches to shoulder; when limbs are laid along the sides, 

 knee and elbow are widely separated ; when hind legs are bent at right 

 angles to the body, heels touch. Skin of upper surfaces finely gran- 

 ular, more heavily so on the sides where some of the larger granules 

 are arranged in diagonal rows ; middorsal area outlined with two sinu- 

 ous rows of closely set granules beginning behind the eyes, converging 

 towards the center of the back, diverging above the sacral region and 

 coming together above the anus; upper ej'^elids and top of snout with 

 coarse granules which form a fairly regular row on the outer edge of 

 the eyelid and along the can thus to nostril; upper arm and leg surfaces 

 finely granular; venter granular, with some coarser granules below 

 the anus. Irregular folds of loose skin in front of groin and along 

 the sides to the axilla. 



Dimensions. — Head and body 29.5 mm.; head length 10 mm., 

 width 12.5 mm.; femur 10 mm.; tibia 10 mm.; foot 10.5 mm., hand 

 7.5 mm. 



Color in alcohol. — Dorsum pearl gray, with a very distinctive pattern 

 of brown spots on the back, the first of these between the eyes, and a 

 second just posterior to it; thi-ee others on each side of the back, 

 meeting the sinuous granular chain; lighter, more irregular markings 

 continue along this chain of granules to the vent; upper lip with four 

 large squarish spots on each side; an irregular brown patch from the 

 tympanic area along the sides to the groin, but more or less interrupted 

 posteriorly; granules below anus white, topping a round, pale buff 

 area extending onto the belly and halfway down the femur, vaguely 

 outlined by pale brown; upper tibia with three wide brown crossbars, 

 and forearm with two similar ones; venter pale buft' with fine, scattered, 

 pale brown dots. 



Remarks. — The small series from Diamantina, kindly loaned to me 

 by the Instituto Butantan, were all very similar to the described 

 specimen.
