XXXIX. Specimens of a rather short and deep bodied species of Boleichthys 

 were collected at Piedrapainte, Texas, by John H. Clark, under Col. J. D. Graham, 

 while connected with the U. S. and Mexican Boundary Survey. We call it B. 

 elegans. The first dorsal fin is longer than the second, and the pectorals extend 

 further back than the ventrals. The formula of the fins is as follows : D x ; 

 12 ; A ii, 8; C 2, 1, 7, 6, 1, 3 ; V i, 5 ; P 12. The scales are of medium size, 

 and larger than in the preceding two species. The ground color is olivaceous 

 brown, maculated with blackish brown. 



XL. In the collections made during the " Exploration of the Upper Missour 

 and Yellowstone," under Lieut. G. K. Warren, there is a species of Boleichthys 

 resembling more B. exilis than any other of its congeners, by the shape of its 

 body and general appearance. It differs, however, from the species just alluded 

 to, by a more compact body, a proportionally shorter head, smaller scales, and 

 the structure of the fins, the rays of which are as follows : D ix ; 11 ; A n, 9 ; 

 C 3, 1, 8, 7, 1, 4 ; V i 5 ; P 13. The ground color is yellowish brown, the mid- 

 dle of the flanks being maculated with transverse spots of blackish; the belly 

 exhibiting a rather orange hue. The first dorsal has a series of vertically elon- 

 gated black spots resembling a dark band across the middle of that fin. The 

 second dorsal and caudal are transversally multilineated. A black streak may 

 be seen in advance to the orbit, and another beneath it. A specimen two 

 inches long was collected by Dr. Hayden, in Cannon Ball river, in September, 

 1856. We propose calling the species B. warreni. 



Catalogue of the Birds of New Mexico as compiled from Notes and Observations 

 made while in that Territory, during a residence of six years. 



By T. CHARLTON HENRY, M. D. 



Assistant Surgeon U. S. A. 



The following catalogue is intended to serve the purpose of a second edition 

 of "Notes derived from Observations made on the Birds of New Mexico, during 

 the years 1853 and 1854," published in the Proceedings of the Academy in 

 April, 1855. 



A residence in the same territory four additional years, has enabled the 

 writer to extend his observations very considerably, and to add much to the 

 varieties heretofore enumerated. 



It will be observed that the nomenclature has been completely modified, in 

 accordance with the extended number of sub-families and sub-genera, which 

 modern science has very generally adopted. 



A few of the species heretofore supposed to belong to certain sub-genera, 

 have, upon more minute inspection, proved to present variations somewhat 

 different from those which then appeared to determine their proper classifica- 

 tion, and have been designated accordingly. 



1. Cathartes aura. 



2. Falco nigriceps. Of this species I never was able to obtain but one indi- 

 vidual, nor am I aware of ever observing others of like character. Met with 

 among the mountains in the vicinity of Fort Stanton. 



3. Gennaia polyagrus. Never more than three or four met with, of which 

 two were procured. 



4. Falco sparverius. Common everywhere. 



5. Accipiter Mexicanus. Rarely met with. 



6. Accipiter Cooperi. Observed about as frequently only as the above. 



7. Buteo calurus. A rare species, never more than eight or ten observed 

 during six years residence in the territory. Of these I was successful in pro- 

 curing four only. This is a remarkably shy and wary bird and exceedingly
