1 Chordeiles texensis, Lawr. 



At a spot called Salitral, between Miravalles and Bagaces, 

 one afternoon I observed a number of these birds flying 

 round a ranch where I intended to pass the night; from 

 these I secured my specimens : at first they were observed 

 at quite an elevation, but as it got later they gradually 

 descended.
