AIMOPHILA BOTTERII PETENICA (Salvin). 

 PETEN SPARROW. 



Similar to ^1. /». sartorii., but smaller (wing-, 55.88; tail, 53.34; tarsus, 

 20.07) and with more rounded wing (ninth primar}' shorter than 

 third). 



Adult female (type, collection Salvin and Godman, pine ridge of 

 Poctum, Guatemala, March, 1862). — Above dark brownish gray or 

 hair brown, everywhere broadly streaked with black, the median por- 

 tion of the feathers being of the latter color, the edges (and on scapu- 

 lars, tertials, rump feather.'?, and upper tail -coverts, the tips also) 

 brownish gray, becoming browner (on some feathers, especially wing- ■ 

 coverts, almost chestnut) next to the black; general color of wings 

 brownish, the darker centers to feathers mostly concealed; edge of 

 wing light yellow; tail brownish dusky, the feathers edged with 

 lighter; lores, narrow orbital ring, malar stripe, chin, throat, and 

 abdomen dull brownish white, the throat and chin margined laterally 



^ Three specimens. 



■•^ Two adult males in the collection of Messrs. Salvin and Godman from El Volcan, 

 Chinandega, Nicaragua (April 28), I refer somewhat doubtfully to this form. They -u 

 are larger and slightl}' different in color, but this may result from the fact that both 9 

 are in very good plumage, while the type, from Huatuseo, and all the Palenque 

 specimens are decidedly worn. Measurements are as follows:
