N'&vo Species of J3irds from Mexico. I*?! 



Remark*. The discovery of this magnificent 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.r ylobicera, 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 distinguish this species from the Cambul (Crax 

 globicera) and call it Bolonchan or Bolonchana. 



It gives me pleasure to dedicate this fine bird to Mr. F. M. Chapman 

 whose interesting 'Notes on Birds observed in Yucatan' (Bull. Am. Mus. 

 Nat, Hist., VIII, 271-290, 1896) is the best local paper we have on the 

 birds of this region. 



Nyctagreus* new genus. 



Type. Caprimulyus yucatanicus Hartert, Cat. Birds British Museum, 

 XVI, 575, 1892. 



Distribution. Yucatan and Campeche, Mexico. 



Generic character*. Bill rather long and narrow; nostrils flattened 

 oval, slightly tubular, situated well forward on bill and opening later 

 ally; rictal bristles coarse, scarcely curved at tips; tarsus a little longer 

 than middle toe without claw and bare of feathers except near proxi 

 mal end, as in Phalwnoptilus; second and third primaries equal arid 

 longest; fourth a trifie shorter; first about 10 mm. shorter than second 

 and about equal to fifth, thus giving a formula very close to Otophanes; 

 tail slightly rounded and a little shorter than wing; plumage and color 

 pattern as in Antrostomus. 



Nyctidromus albicollis yucatanensis new subspecies.
