Leticia, Amazonas, Colombia).

As no additional specimens have come to hand, the original descrip- 

 tion (Cochran and Goin, 1959) is repeated, as follows: 



Type. — USNM 140245, adult male, collected in the forest near Leticia, Ama- 

 zonas Comisaria, Colombia, during March, 1956, by E. Ross Allen. 



Diagnosis. — A large Limnomedusa with extensive webbing between the toes, 

 and extensively developed dark mottlings on the ventral surface of the body and 

 legs. From both macroglossa and misionis, it differs in being much larger (82.0 mm. 

 snout-vent length as compared to 49.0 for a large female misionis and 58.6 for 

 the largest macroglossa at hand). 



From both of these forms it also differs in having the toes much more exten- 

 sively webbed, the web extending to the base of the penultimate phalanx of the 

 fourth toe and to the base of the ultimate phalanx of the other toes. In schmidti 

 the vomerine tooth patches are slightly larger and more arched than in macroglossa.
