Remarks. — Although Physalaemus cuvieri is the commonest and 

 most widespread member of its genus in Brazil, it does not seem to 

 occur near the city of Rio de Janeiro or in the coastal region of the 

 State. Its place is taken by a Physalaemus originally described by 

 Girard as Rhinoderma signifera, from Rio de Janeiro, and later by 

 L. Miiller as Paludicola hresslaui, from Teresopolis in the Serra das 

 Orgaos which form a part of the coastal range. While the type of 

 Girard's signifera has been lost, the original description appears to 

 agree in every phase with Miiller's description of bresslaui. 



P. signiferus shows considerable similarity to Eupemphix nana 

 Boulenger (1888a, p. 187; type locality, Lages, Santa Catarina). 

 The snout in the cotypes of nana is less prominent, and maxillary 

 teeth are lacking in that species, while in signiferus the snout is more 

 prominent, and maxillary teeth are present although poorly developed. 

 While Eupemphix nana can now be assigned to the genus Physalaemus, 

 more specimens should be collected and studied to find out to what 

 degree the shape of the snout varies, and whether maxillary teeth may 

 occasionally be found. 



Examples of signiferus were compared with the type of Paludicola 

 bresslaui L. Miiller, and the two were found to be identical by Dr. 

 Miiller and me.
