jSfew Species of liirds from Mexico. 171 



Bemarks. — The discovery of this mag'nificent bird, one of the largest 

 and handsomest of the genus, was a quite unexpected result of our work 

 in Yucatan. Only a single specimen could be secured by us, although 

 the feathers of others were seen about Indian camps in southern Cam- 

 peche in December, 1900, by Mr. Goldman, and I came on a hunter in 

 the forest in eastern Yucatan just after he had finished plucking one. 

 They were evidently much less common than Cra,v gloMcera, though 

 they frequent the same forests. Unfortunately we failed to secure a 

 male so this sex remains unknown. The ovaries of the type were be- 

 coming enlarged showing that the breeding season was near, at the date 

 of her capture. 



The Maya Indians distinguisli this species from IheCambul {Cra.v 

 globireni) and call it Bolonchan or iU)l()nchan!i. 



It gives me pleasure to dedicate this tine bird to ^Ir. F. M. Chapman 

 whose interesting 'Notes on Birds obser\ed in Yucatan" (Bull. Am. Mus. 

 Nat. Hist., VIII, 271-290, 189()) is the best local paper we luive ou the 

 birds of this region.
