f. 106. PiPRA MENTALIS. 



Pipra mentalis, Scl. Cat. B. Brit. Mus. xiv. p. 295. 



Meco I. (November) ; Mugeres I (December). 



These specimens agree accurately with mainland birds. 

 The species has a wide range from Southern Mexico to 

 Panama. 



-L107. Hadrostomus aglai^. 



Hadrostomus aglaice (Lafr.) ; Scl. Cat. B. Brit. Mus. xiv. 

 p. 335. 



Holbox I. ; Cozumel I. 



The female I left undetermined from Mr. Devis's collec- 

 tion is placed by Mr. Sclater with this species. Never- 

 theless it has a bill much larger than typical examples of 

 H. aglaice. Examples from Northern Yucatan have bills 

 larger than usual, and the males are of a rather pale colour. 

 With my present materials I think it best to adhere to 

 Mr. Sclater's determination. 



•/ 108. AtTILA COZUMELyE. 



Attila cozumeke, Ridgw. Proc. U.S. Nat. Mus. viii. p. 572. 



Attila, sp.?, Salv. Ibis, 1885, p. 191. 



Cozumel I. 



Many examples. 



This seems to be a species distinct from A. citreopygius. 



r-109. Attila CITREOPYGIUS? 



Attila citreopygius (Bp.); Scl. Cat. B. Brit. Mus. xiv. 361. 



Meco I.; Holbox I. ; Mugeres I. 



The birds from these more northern islands agree better 

 with those of the mainland than with the Cozumel birds. 

 They have paler rumps, and several of them a slight wash of 

 olivaceous over the chest. I do not at present understand 

 the variations found in several forms of Attila^ A. citreo- 

 pygius amongst them, so that I am obliged to leave the accu- 

 rate determination of them for the present.
