* AURIPARUS, Bainp. 
Auriparus, Barrp, n. g. (Type 4yithalus flaviceps, Sunp.) 
In the “ Birds of North America,” p. 399, while defining the generic 
characters of Paroides, I showed that the Agithalus flaviceps, of 
Sundevall, differed very materially from the P. pendulinus, the type 
of the genus. The discrepancy, in fact, is too great to permit the 
two species to be associated, and I have consequently been obliged 
to establish a new generic name. The peculiarities authorizing this 
course will be found detailed in the work cited above. They con- 
sist, as compared with other American forms, in the long pointed 
quills, and the very small claws; the tarsi are much shorter than 
in Psaltriparus. 
The single known species of the genus builds a covered nest of 
stiff, short pieces of grass, with a hole in the side, in bushes. The 
eggs are spotted, as in the Black-headed Titmice, not white, as in 
Psaltriparus minimus.

Hab. Valleys of the Rio Grande and Colorado: Cape St. Lucas. 
This interesting species appears confined to the basins of the Rio 
Grande and Gila, extending to Cape St. Lucas, where it is very 
abundant. An immense number of its curiously shaped nests were 
collected by Mr. Xantus. Cape St. Lucas specimens of this, as 
of the other species, are much smaller than those from the more 
northern localities: thus, in No. 12,967, $, the wing measures 1.90,
