Agyrtria alleni, a species not identified by Salvin and Hartert, proves to have 

 been based upon a female of C. oenone josephinae, a well-known Bolivian Humming- 

 bird. The type specimen is practically identical with a female from Songo, western 

 Yungas, in the Berlepsch Collection.* They agree in the dull bluish green tint of 

 the forehead and crown, and in the reddish bronze tail, the three outer pairs of 

 rectrices having, in both specimens, a distinct, pale greyish apical spot. Like the 

 Songo example, the type has the throat and malar region spotted with glittering 

 golden-green on a white ground, these spots being absent on the chin and but barely 

 indicated along the median portion of the upper throat ; the foreneck is white, with 

 bronze-green (not glittering) apical edges ; the remainder of the under parts dull 

 white, washed with metallic green on the flanks ; under tail-coverts pale greyish, 

 edged with whitish, upper tail-coverts fiery reddish bronze, much the same as in 

 the Songo bird. The bill, in Nos. 1 5, is quite alike both in shape and colour, the 

 maxilla being black, the mandible pale brownish with dusky tip. 



Count Berlepsch,, who has seen the type, entirely concurs with my identification. 

 Agyrtria, alleni is consequently to be placed among the synonyms of C. o.josephinae, 

 whose range appears to be restricted to the forests of Bolivia. 



65. On the group of Saucerottia sophiae (Bourc. & Muls.). 



The latest reviewer, Mr. Ridgway,t distinguished four races of this group, 

 calling them : Saucerottia sophiae sophiae (Costa Rica and Nicaragua), S. sophiae 

 saucerottei (Western Colombia), S. sophiae warscewiczi (Northern Colombia), and 

 S. sophiae braccata (Andes of Venezuela). The specific names are applied in the 

 same sense as by Dr. Hartert, J who, however, separated S. sophiae, S. saucerottei 

 and S. warscewiczi specifically, regarding S. braccata as a subspecies of the last- 

 named form. To my mind the arrangement put forward by Ridgway is the most 

 correct expression of the natural affinities of these birds, which agree in structure as 

 well as in general style of coloration, and present only slight (though perfectly con- 

 stant) differences in the colour of the upper and under tail-coverts. 



Trochilus Sophiae Bourcier et Mnlsant, though originally based upon 

 Bogota skins, has generally been referred to the Costa Rica form with coppery or 

 purplish bronze rump and mainly steel-blue under tail-coverts. This misapplication 

 of the name is evidently due to the fact that the alleged type, in the Elliot collec- 

 tion (now the property of the American Museum of Natural History), marked 

 "Nicaragua" || belongs to the Central American race. However, on consulting
