FROGS OF SOUTHEASTERN BRAZIL — COCHRAN 157 



that of upper eyelid, a little greater than interval between nostrils. 

 Tympanum distinct, small, about two-fifths the diameter of eye, 

 separated from eye by an interval equal to two-thirds its own diameter. 

 Fingers webbed only at the base, fourth much longer than second, 

 reaching almost to base of disk of third, which covers the tympanum ; 

 no rudiment of a pollex; toes one-half webbed, third and fifth subequal, 

 disk of fourth covering tympanum; a small oval inner but no outer 

 metatarsal tubercle; subarticular tubercles well developed on fingers 

 and toes; no tarsal ridge or dermal heel appendage. Body elongate, 

 in postaxillary region much less than greatest width of head; when 

 hind leg is adpressed, heel reaches to nostril; when limbs are laid 

 along the body, knee and elbow overlap considerably; when hind 

 legs are bent at right angles to the body, heels greatly overlap. Skin 

 of upper parts with numerous pointed tubercles especially prominent 

 on upper eyelids, between the eyes, and on loreal region; a single large 

 tubercle in center of canthus rostralis and others around the tym- 

 panum; tubercles on back smaller and more widely spaced, those on 

 sides more closely set; a few weak tubercles on forearm and tibia; 

 throat and belly coarsely granular, edges of chin nearly smooth; 

 granules extending into axillary region; postanal surface and lower 

 femur finely granular; no apparent skinfold across chest. (Male with 

 a median external vocal sac (?).) 



Dimensions. — Head and bod}^ 40 mm.; head length 14.5 mm., 

 width 15 mm.; femur 19 mm.; tibia 22 mm.; foot 17.5 mm.; hand 

 13.5 mm. 



Color in alcohol. — Dorsum pale wood brown, with traces of a wide 

 dark brown bar between the eyes; each tubercle with a brown spot 

 covering it; femur with four wide, dark brown bars separated by 

 narrow light interspaces, this pattern continued over tibia and 

 foot; forearm with two similar wide brown bars; upper lip with three 

 dark slanting brown spots separated by white lines, the central spot 

 extending to lovrer eyelid; venter pale buff with a fine reticulated 

 pattern of minute dark dots, entirely covering lower surfaces. 



Color in life. — A sketch by Sandig of an adult female, IOC, 

 from Passa Quatro, has the triangular spot on the head and other 

 features of the usual dorsal pattern very greatly reduced. In the 

 vivid orange spots on anterior surface of femur as well as on inguinal 

 region, and in most structural details, the example agrees with typical 

 catharinae (see pi. 13, figs. h,j). Its living coloration taken from the 

 sketch was as follows: Back sepia to drab with many small darker 

 spots thickly sprinkled over it; a faint light interorbital bar followed 

 by a suggestion of a dark brown marking fading out quickly into the 

 surrounding dorsal color; limbs olive-buff above with smaU drab- 

 gray spots and faint reticulations on arm and tibia, stronger across
