Pionites Heine. 

 My reasons for using the generic name Caica Bp. (nee 

 Less.) in preference to Pionites have not been accepted by 

 Dr. Sharpe (' Hand-list/ ii. p. 25) nor by Mr. Hellmayr 

 (Nov. Zool. xii. p. 302) ; and I submit to their verdict, 

 although it appears to me that the reasons for so doing are 

 not quite satisfactory.

PYOCEPHALUS Sw. 



Since the publication of vol. xx. of the 'Catalogue of 

 Birds ' several species of this genus have been divided and 

 many subspecies have been described ; but their characters 

 are so very slight that I doubt whether, without the help 

 of the locality, they would be recognised by the authors 

 themselves. This is the case with the forms of P. robustus, 

 P. fuscicollis, P. flavifrons, and especially of P. meyeri.
