Agrees perfectly with the type from the Ucayali River in the British Museum. 



The characters of this form have been pointed out by Menegaux and Hellmayr 

 in the Bull. Soc. Philomat. Paris, 1906, pp. 48-49. Its distribution thus far known 

 is as follows : 



Eastern Pern : Ucayali River (Bartlett), Samiria (Hanxwell), Pebas, Nauta 

 (Castelnan and Deville). N.W. Brazil: Humaytha, Rio Madeira (Hoffmanns), 

 Rio .lunia (Garbe), Teffe, Rio Solimoeus (Hoffmanns). 



I hope to discuss the geographical races of M. surinamensis and its allies 

 more fully on another occasion.
