NO, 14 THE RACES OF PELLORNEUM RUFICEPS DEIGNAN 7 



Specimens examined. — Assam: Garo Hills District: Tura (i 

 male), Rangsakona (i unsexed) ; Cachar District: Gunjong (i male, 

 2 females), Mahu (i male). 



Remarks. — Pellorneiim intermedium was said by Bowdler Sharpe 

 to range "from Cachar to the neighbourhood of Thayetmyo" ; as will 

 be found explained under P. r minus, this name is best restricted to 

 the population of Thayetmyo, and the quite different birds of northern 

 Cachar may then safely be called as above. 



6. PELLORNEUM RUFICEPS PECTORALE Goawin-Austen 



Pellorneiim pectoralis [sic] Godwin-Austen, Journ. Asiat. Soc. Bengal, vol. 

 46, pt. 2, No. I, May 12, 1877, p. 41 (Sadiya, Sadiya Frontier Tract, Assam 

 Province, India). 



Diagnosis. — Similar to P. r. mandellii in having sharply defined 

 blackish-brown centers to the feathers of the uppermost back, but 

 differing in having the rufous of the front, crown, and nape much 

 deeper in tone (rufous chestnut) ; the brown of the remaining upper 

 parts decidedly darker ; the under parts more heavily washed with a 

 richer (sometimes almost rufescent) buff. 



From P. r. chamelum immediately separable by its much more 

 saturate coloration above and below. 



Range. — Northeastern Assam (Sadiya Frontier Tract). 



Specimens examined. — Assam : Sadiya Frontier Tract : Tezu ( i 

 male, i female). 



Remarks. — Inasmuch as a form different from pectorale occurs so 

 near Sadiya as Dibrugarh and Margherita, it was of some importance 

 to learn whether Godwin-Austen's type was taken literally at Sadiya 

 and thus represented the dark population found north of the Brahma- 

 putra. Dr. Dillon Ripley has kindly investigated the matter for me in 

 London and writes that Ogle took the type and four others along the 

 Brahmakund road east of Sadiya and that all are of the darker race. 



7. PELLORNEUM RUFICEPS RIPLEYI, new subspecies 



Type. — A.M.N.H. No. 588323, adult male, collected at Margherita, 

 Lakhimpur District, Assam Province, India, on December 21, 1901, 

 by H. N. Coltart {ex Rothschild Museum). 



Diagnosis. — Similar to P. r. mandellii in having sharply defined 

 blackish-brown centers to the feathers of the uppermost back, but 

 differing in having the rufous of the front, crown, and nape slightly 

 richer in tone; the brown of the remaining upper parts much more
