This species was discovered by Mr. Alexander in Mexico, 

 and it was dedicated to him by Messrs. Bourcier and

It is a rare species ; but I have been fortunate in getting a 

 fine series from San Diego, co. California. 



3. Trochilus Violajugulum, Jeff. Auk. 1888, p. 168. 



Purple Throated Humming Bird. Oiseau tnouche a gorge 

 violette. Habitat. Santa Barbara (California), 



Male. — Upperside metallic green and gold, dull on forehead. 

 Throat metallic violet with bluish reflections. Chin and line 

 between gorget dull, a dull gray belt across the breast behind 

 the throat. Breast and abdomen metallic green. Flanks green 

 tipped with brown, ventral medium lines dullish. Wings 

 purple-black. Primaries broad to tip, that of the first curved 

 back, graduated in length from first to last. Tail slightly forked, 

 feathers broad except the last pair, which are abruptly narrow 

 and linear. Middle feathers and base of second pair, metallic 

 green, rest dark with a distinct purple hue. Under tail-coverts 

 white with metallic green central spots. 



* Although I give the total length for each species, it is not to be 

 relied upon, in the strict sense of the word ; as the total length depends 

 entirely from who prepared the skin. It is just as easy, when skinning, 

 to shorten or lengthen the skin, by one inch, less or more, according to 

 size of bird.
