arm to side of body. Skin of upper parts highly smooth; a pair of 

 rounded glandular areas in the pectoral region; a rather narrow but 

 well-developed glandular ridge encircling upper part of tympanum; 

 skin of throat and chest smooth except for glandular areas mentioned 

 above, that of belly and lower surface of thigh uniformly and very 

 finely granular; a well-developed skinfold across chest; adult male, 

 vocal sac apparent only as a loose gular fold. Skin of head not co- 

 ossified with skull, roof of skull not exostosed. 



Dimensions. — Head and body, 24 mm.; head length, 8.7 mm.; head 

 width, 8.7 mm.; femur, 11 mm.; tibia, 12.5 mm.; heel-to-toe, 16.5 

 mm. ; hand, 6.7 mm. 



Color in alcohol. — The specimen is uniform tan on the top of the 

 head and dorsum. The upper surfaces of lower arms, hands, shanks, 

 and the tops of the feet are densely mottled with tan. The thighs 

 are immaculate except for a thin row of tan flecks along the dorsal 

 surface. The upper lip and loreal region are brownish rather than tan; 

 there are a few flecks of tan along the margin of the lower jaw. The 

 ventral surface is otherwise immaculate. 



Coloration in life. — When collected this specimen was a rich brown 

 above, dotted with discrete, small golden spots. These golden spots 

 have all but disappeared in preservative. 



This specimen was collected in open, wet pasture lands. Its call 

 was loud and Pseudacris-like, being comparable to the noise produced 

 by rubbing the teeth of a comb. 



Remarks. — The junior author suspected that this specimen was a 

 novelty at the time he described other species from the same collection 

 (Goin, 1957), but he refrained from naming it in the hope that 

 additional material would become available. No one has yet been 

 successful in collecting more specimens and we cannot see that any- 

 thing is to be gained by withholding the description any longer. We 

 are happy to name this species for Olive Bown Goin, in recognition 

 of the help she has given us on this manuscript.
