" Tehuantepec (San Mateo, Santa Efigenia) ; August and January, .

^' Iris dark-brown ; bill brownish; feet dull-brown. 



"At Santa Efigenia, where I killed most of the specimens of this 

 Kight-hawk, they live during the day hidden at the foot of mountain 

 in woods and thickets. They come out a short time after sunset, and 

 then appear in great numbers above inundated places and savannas. 

 Their flight is easy and graceful ; but it is quite difficult to shoot them, 

 because they easily escape from sight on account of their dark color 

 and the feeble light of the twilight." 



168. Antrostomus vociferus (Wils.). 

 " Tehuantepec City ; November, 1869." 



169. IVyctidromus albicoUiis (Gm.). 



" Tehuantepec (Chihuitan, Santa Efigenia) ; November, December, 

 and January. 



" Iris dark-brown ; bill pale-brown, tip dusky ; feet dull-fleshy. 



" This species is very common in all the warm and temperate lands 

 of Southern Mexico, where it is known under the name of Tapas camina 

 {conore cliemin) or Ataja camina [qui embarrasse le cliemin), derived 

 from the custom it has of lying flat on the roads. Its cry, which is of 

 two kinds, may be expressed by the syllable piou -piou - piou - piou — 

 pu - e - i - ou. The latter part, uttered with force, is probably a cry of 

 appeal (or challenge). The second, which it repeats from time to time, 

 is shorter, ou - i - iouJ^
