298 TROCHILID^. 



Salvin found it near Retalhuleu and Mazateuango in September 1862. Mr. Richardson 

 also met with it in the same district in April 1891. Thus in all probability the range 

 of the species extends uninterruptedly from Guatemala, close to the Mexican frontier, 

 to Nicaragua.

Hah. Mexico, Jalapa {de Oca ^ ^ ^), Paso del Macho % [de Oca ''). 



The type specimen obtained by de Oca at Jalapa and described by Gould in 1859, 

 and subsequently figured in his Monograph, is the only one we have seen ; nor have 

 we any other information regarding the species unless the bird described by de Oca as 

 Thaumatias lerdi belongs to it, as seems to me to be not improbable. 



The latter name was placed by Mr. Elliot as a synonym of Agyrtria norrisi, which 

 was considered by Gould to be a second member of his genus Hemislilbon, A. ocai 

 being the type. 



Gould also gave the habitat of A. norrisi as Bolanos, but on what grounds he did so 

 is not apparent. Bourcier, the author of the name, gave its locality as Guayaquil, 

 and we believe the bird to be the same as Amazilia dumerilii. 



" Agyrtria norrisi " therefore must be erased from the list of Mexican Humming- 

 Birds.
