Closfily resemblcs C. aur'Ua, Temm., from which it difFers in ■\vant- 

 ing black spots to the wings, in having a less rounded tail without 

 the black band, and in the wing coverts being rufous, and not grey.

In our speciraens, perhaps arising from immaturity, the throat is 

 vhitish, and not black.

Among the numerous Ortyges lately discovered in Mexico, and 

 especially among the crestless species, the Ortyx Monteziima, of 

 which we now, for the first time, introduce the female to the notice 

 of naturalists, is the most handsome.

 AU the Mexican specimens I have seen are of a much darker tinge 

 and of a larger size than the Brazilians. 



II. Having lately, through the kindness of Colonel Velasąuez de 

 Leon, had an opportunity of examining a coUection of birds, formed 

 by hira during a fortnight's scientific tour in Guatamala, I think it 

 desirable to give the Societ)' a list of the known species contained in 

 it, A\nth concise descriptions of those birds which appear to me to be 

 new. I hope they may prove not uninteresting to the naturalist, 

 for whom that part of Central America possesses attractions not in- 

 ferior to those of any other country.

2. BuTEO. A species which I am un\^-illing to give a name to, 

 owing to the immature statė of the only specimen I have seen. 



lt is of an ashy brown colour, -vvith the vent feathers whitish, 

 banded with rūsty. The wings reach a little beyond the middle of 

 the tail ; the primaries are rūsty red, with black bands except at the 

 tip. The tail-feathers ashy, with four \vide black bands.
