b The types were supposed to have come "from that little explored district of Cali- 

 fornia which borders the territory of Mexico;" but according to Salvin and Godman 

 (Biol. Centr.-Am., Aves, ii, 1895, 445) they were probably collected by "the mining 

 engineer Floresi, who formed a considerable collection of humming-birds, and also 

 preserved skins of a few other species, all of which passed into Gould's possession," 

 in the neighborhood of Bolanos, in the Sierra Madre of Jalisco, where the species is 

 known to occur, and where Floresi was for a time stationed.
