the type (Hemiphaga forsteni Bonaparte) being Carpophaga poliocephala 

 Gray. They indicated the sections into which the genus can be divided, 

 but unfortunately provided no names for these sections, probably because 

 following Salvador! they only recognized Zonophaps as a subgenus of 

 Carpophaga. 



Diopezus, gen. nov. 



Type, Phlegaenas tristigmata Bonaparte. 



Similar to Gallicolumba Heck (type Columba luzonica Scopoli), but the 

 tarsus about a fifth longer than the middle toe with claw, instead of nearly 

 equal; the breast spot of decomposed feathers more diffused and of a diff- 

 erent texture; bill heavier, the covering of the nostril proportionally less 

 swollen; type of coloration different. 



Remarks. — Dr. Chas. W. Richmond' has shown that Plegoenas Reichen- 

 bach, 1851, is antedated by Gallicolumba Heck, 1849, both names having 

 the same type. The group of pigeons placed by authors in Plegoenas 

 (usually written Phlogoenas, but there are many variations) is a composite 

 one and needs revision, but which I have neither the material or inclination 

 to undertake at present. Phlegaenas tristigmata Bonaparte is so aberrant 

 that it should be removed, however. 



Cranobrontes, gen. nov. 



Type, Buceros leucocephalus Vicillot. 



Similar to Cranorrhinus Cabanis and Heine (type Buceros cassidix 

 Temminck), but maxilla without a grooved plate at the base; casque 

 smaller, not so arched, and corrugations more pronounced; the two 

 outer primaries more attenuate at the tip. 



The three species of the genus will stand as : 

 Cranobrontes leucocephalus (Vieillot). 

 Cranobrontes corrugatus (Temminck). 

 Cranobrontes waldeni (Sharpe). 



Remarks. — Meyer and Wiglesworth^ have suggested that Cranorrhinus 

 be restricted to the Celebes species and as it is clear that the other three 

 species usually placed in the same genus are not congeneric I have acted 

 upon their suggestion. 



Orodytes, gen. nov. 



Type, Arach7iothera? celebensis Meyer and Wiglesworth. 



Similar to Stigmatops Gould (type, .Glyciphila octdaris Gould) but the 

 bare skin around the eye more extensive, extending above as well as below 

 the orbit; the eyelid above and below surrounded by small feathers, these 

 feathers meeting behind on the naked area; ear-coverts not composed of 

 small specialized silky feathers; bill proportionally longer and heavier 

 (culmen much longer than the tarsus instead of only slightly); tail roun- 

 ded instead of truncate; body feathers coarser and harsher, not so blended 

 and silky.
