This genus contains the single species B. pachyrhynchus, which resembles some of 

 the Macaws in size, but differs from them in having the lores feathered as in Conurus. 

 From the latter genus it can be distinguished by its much more compressed bill, the 

 mandible being flattened and grooved in front, the culmen of the maxilla rounded, and 

 the nostrils completely hidden. The known range of the genus is restricted to Central 

 and Northern Mexico, but it probably crosses the border into South-western Texas 

 and Southern New Mexico ; the details of its distribution are given below.

This very distinct species of Parrot was discovered by Bullock on the tablelands of 

 Mexico, and described by Swaiuson in 1827 as Macrocercus pachyrhynchus ^ Specimens 

 were shortly afterwards sent to Berlin by Deppe, and called Psittacus strenuus by 

 Lichtenstein ^^, and then P. pascha by Wagler i*, the latter name being a substitute 

 for that of Swainson. 



Its range seems restricted to the highlands of Mexico ; and Sumichrast names 

 Popocatepetl, Mozoapam on the volcano of Orizaba, and the Cofre de Perote as 

 upland localities where it is to be met with «. De Oca's collection from Jalapa 3 

 contained specimens which probably came from the Cofre de Perote. None of the 

 collectors recently employed by us in Mexico met with this bird; but Mr. Forrer
