NO. 14 THE RACES OF PELLORNEUM RUFICEPS — DEIGNAN 9 



road (i male), Lonkin (i female); Bliamo District: Bhamo (2 

 females). 



Remarks. — Two females (i from NTon, i from Lonkin) must be 

 considered "erythros" (a neologism constructed by analogy with 

 "melano"). Although they are, especially above, less rufescent than 

 examples of ripleyi, yet they approach them below in the amount of 

 rich buffy wash and in having the streaks on the breast and sides of 

 the abdomen brownish and therefore less clearly demarcated from 

 the ground color than is the case with the other specimens of stageri 

 (which have the streaks blackish and the ground color bufify white). 



Differences between stageri and "pectorale" {=ripleyi) have al- 

 ready been commented upon by Mayr (Ibis, ser. 14, vol. 5, 1941, 

 p. 69). 



The new race is named for Kenneth E. Stager, Curator of Orni- 

 thology and Mammalogy at the Los Angeles County Museum of 

 History, Science and Art, who collected the type specimen while 

 serving as a member of the United States of America Typhus 

 Commission. 



9. PELLORNEUM RUFICEPS SHANENSE, new subspecies 



Type. — A.M.N.H. No. 143416, adult female, collected at Ma-li-pa 

 (lat. 23°4i' N., long. 98°46' E.), Kokang State, Burmese Wa 

 States, on March 15, 1917, by Roy C. Andrews and Edmund Heller 

 (original number 567). 



Diagnosis. — Differs from the five races immediately preceding by 

 having obsolescent deep brown centers to the feathers of the upper- 

 most back, much as in P. r. punctatum. 



From P. r. stageri, the geographically nearest form, distinguished 

 also by having the rufous of the front, crown, and nape somewhat 

 paler and brighter ; the brown of the remaining upper parts paler and 

 rather more olivaceous; the central streaks of the feathers of the 

 breast and sides of the abdomen much narrower and less numerous ; 

 the ground color of the under parts intermediate between the two 

 extremes shown by the series of stageri (discussed above). 



Range. — The parts of Burma and southwestern Yunnan lying be- 

 tween the Mekong and Salween Rivers. 



Specimens examined. — Yunnan: Southwest: Chaunglung (i 

 male); Burma: Kokang State: Ma-li-pa (i female); Kengtung 

 State: Loi Mwe (i female), Mong Len (2 unsexed). 



Remarks. — The three specimens from Kengtung State have been 

 discussed by Meyer de Schauensee (Proc. Acad. Nat. Sci. Philadel-
