[Note. — The general drift of this list reminds one of that of Dr. S. W. Woodhonse 

 (Sitgreaves's Exploration of the Zuui, &c.), though the latter contains various species 

 from further southwest not represented iu the region explored by Lieutenant McCauley . 

 The ornithology of the country traversed by the latter is interesting from the number 

 of species more or less perfectly characteristic of the Eastern province, which there 

 meet with Western species, producing some novel combinations. I have examined but 

 Tery few of the specimens collected by Lieutenant McCauley: presuming, however, 

 upon his accuracy of identification throughout, we have the following unusual juxta- 

 positions of species : — 



Eastern. — Protonoiaria citra'a, HehnHherus vermivornn, Dcndrocca dominica, Pyranga 

 (PKtiva, Euspiza americana, Cyanospiza ciris, C. cyanca, Card'niaUs vlrginianns, Icterus t<purius 

 I, haliiinore, Myiarchns crinitus, Ortyx virginiaua, Meleagris amei'icana. 



Western. — Catherpes cotispersus, Passerciihis hairdi, Peiiccea casnini, Sjy'tzelfa hreweri, 

 Chondestes grammaca, Cahimospiza bicolor, Goniaphea melaiiocipliala, Pyrrhuloxia sinuata 

 Ictei'ushuUocki, CorruH crypUileucHS, Milviihis forfiailus, Tyrannus viHicalis, ilyiarchits cinc- 

 rascens, Sayornissayus, Antrostomus nntlalU, Geofoccyx calif ornianus, Picus acalaris, Speotytj 

 hypogcBtt, Fulco mexicanus. — Ed.]
