Chordeiles Henryi, described by Mr. Cassin as distinct, is probably only 

 a lighter race of this species, iu wliich the markings are more distinctly 

 appreciable, owing to the lighter color.

On the 17th of April I saw tlie first of tliis .species at Fort Mojave, and 

 soon after they became quite numerous, hunting in comimny after sunset, 

 and hiding during tlie day on the around under low bushes. About the 



25th of May they were paired, but continued nearly silent, making only a 

 loAV croaking when approached. Tliey flew like C. j>o2Ktue, but sailed rather 

 more in small circles. I found them common as far west as the Coast 



Mountains, 

 species. 



The eggs are said to be much paler than those of the other
