female of Ithaginis clarkei (in the skin) ; red with only the cere and 

 extreme base blackish in Ithaginis rocki. 



Rothschild " reduces Ithaginis clarkei to a race of Ithaginis geof- 

 froyi^ but Ithaginis rocki is a connecting link to Ithaginis cruentus, 

 so it would seem that even Ithaginis geofroyi would have to be re- 

 duced to a race of that species or treat them all binomially; I have 

 adopted the latter course for the present. 



4. ITHAGINIS ROCKI Riley 



Ithaginis rocki Riley, Proc. Biol. Soc. Wash., vol. 38. 1925, p. 9 (Hofuping 

 Mountains, Mekong Valley, Yunnan). 



Three males and three females, Hofuping Mountains, Mekong 

 Valley, November. 



Similar to Ithaginis kuseri Beebe, but bar coverts broadly streaked 

 with grayish-white and the lores black not red. 



There are no specimens of /. kuseri available for comparison. I 

 have had to rely upon descriptions and the plate of the head given by 

 Stuart Baker.'^ The above birds do not fit the descriptions or the 

 plate, and as there did not appear to be any described form to which 

 they could be referred, I named it after its discoverer. 



One of the specimens marked as a female has the bill black, only 

 red at the base of the lower mandible. In my opinion it is a young 

 male, as the tarsi are heavier than in the female and have a budding 

 spur. The female resembles the females of Ithaginis clarkei Roths- 

 child, but the hind neck is not so extensively neutral gray ; the fore- 

 head, cheeks, and throat are cinnamon-rufous, not tawny-olive; and 

 the bills are smaller and red, only black basally, not wholly so. 



The birds of this genus are residents of high mountain regions and 

 seem incapable of crossing hot valleys. It would appear as if every 

 isolated high-mountain mass within the range of the genus that had 

 been sufficiently long uplifted might have its own local race. When 

 the same form occurs upon two or more disconnected mountain 

 ranges it tends to show that at one time there must have been a con- 

 nection and that they are near the same geologic age. The distribu- 

 tion and relationships of the various forms are too imperfectly 

 known as yet for any one to dogmatize.
