along the side; heel extending to anterior margin of eye when leg is 

 pressed along body. A well-developed patagium. Venter strongly 

 rugose, but undersides of thighs and chin nearly smooth; no well- 

 marked external vocal pouch. There is a pair of glandular areas in 

 the skin of pectoral region. Each area is about four millimeters in 

 diameter and lies just posterior to the insertion of arm. The paired 

 glandular areas do not quite meet on the median line. 



Color in alcohol. — Ground color on top of head, dorsum, top of 

 arm, and top of shank a light tannish gray; a single median row of 

 dark, chocolate brown spots extends from between the eyes to just 

 posterior to the sacral hump. These spots are roundish and each is 

 about a millimeter, or slightly more, in diameter. A dark stripe of 

 the same nature extends from behind each eye through the tympanum 

 and then breaks up into a row of spots similar to, but slightly smaller 

 than, those on the back, and continues along the side to groin. Dark 

 spots similar to those in the row along the side occur on top of arms, 

 the shanks, and the feet. The upper lip is whitish, and rounded, 

 brownish spots are distributed on the loreal region and upper lip. 

 Brown flecks are distributed along the margin of the lower jaw, 

 otherwise the entire ventral surface is immaculate. 



Dimensions. — Head and body, 25.6 mm.; head width, 9.5 mm.; tip 

 of snout to posterior margin of tympanum, 7.8 mm.; diameter of 

 eye, 3 mm.; diameter of tympanum, 1.2 mm.; thigh, 10.9 mm.; 

 shank, 13.1 mm. ; heel-to-toe, 15.8 mm. 



Color in lije. — In life the ground color of the dorsum was yellow 

 and the spots were a rich brown. The hands, feet, and thighs were a 

 bright salmon pink, and the venter was tinged with the same color. 



Variation. — Since no additional specimens have been collected since 

 the type series was taken, we quote the comments on variation from 

 the original description (Goin, 1957, p. 61) : 



In dorsal ground color one of the paratypes is lighter than the type, the other 

 darker. In the specimen with the lightest ground color the dark brown spots are 

 double at two places along the back and between the eyes, thus giving the im- 

 pression of a double row of spots down the back. In the darkest specimen the 

 ground color is a light brown and consequently the dark brown spots do not 

 show up quite so prominently. In this specimen there are five spots in the mid- 

 dorsal row, not counting those on top of the head, and the spots are somewhat 

 smaller than in the other two individuals. In life this specimen had a dorsal 

 ground color of tan and the under parts of the abdomen and hind legs were salmon 

 pink. 



Structurally there is but little variation amongst the three specimens. The 

 other two do not have the patagium quite so well developed as the type but even 

 in them it is prominent. In none of the three is the external vocal pouch prominent. 



Both of the paratypes are 24.7 mm. in head and body length. 



Remarks. — The type was collected while the frog was calling in a 

 wet meadow; the two paratypes were taken in grass growing in the
