THE BIRDS OF NORTHERN THAILAND 93 



This bird has a proportionately much longer tail than other northern 

 partridges. The adult has the crown dull rufous-brown ; a collar on 

 the hindneck, the quills, and tail feathers rufous ; the remaining upper- 

 parts gray-brown, the upper back, scapulars, and wing coverts marked 

 with chestnut-bordered black drops or spots; a black or rufous stripe 

 back from the eye, edged above by a white supercilium ; the throat and 

 sides of the neck buff; the breast rufous, mottled with buffy white; 

 the remaining underparts buffy or whitish, boldly spotted and barred 

 with black. 



GENNAEUS CRAWFURDII LINEATUS (Vigors) 



Peguan Lineated Pheasant 



Phasianus lineatus "Lath. Mss." Vigors, Proc. Comm. Sci. Corr. Zool. Soc. Lon- 

 don, pt. 1, 1830-1831 [=1831], p. 24 (Straits of Malacca, error; East Pegu 

 Hills designated as type locality, by Ticehurst, Journ. Bombay Nat. Hist. 

 Soc, vol. 36, 1933, p. 936). 



Gennaeus lineatus sharpei, Riley, U. S. Nat. Mus. Bull. 172, 1938, p. 67 (Mae 

 Sariang). 



The range of the lineated pheasant is apparently restricted to the 

 lower elevations of the hilly districts of western Thailand. The only 

 specimen known to me from the northern provinces is a male taken 

 by Dr. Hugh M. Smith at Mae Sariang, January 20, 1935. I have 

 another male example, collected and kindly presented to me by T. W. 

 Bevan, Esq., from Kaeng Soi (in the Mae Ping Gorges, just beyond 

 our limits), on the right bank of the river, March 16, 1936. 



Dr. Smith records that his bird had the irides hazel ; the bare skin 

 at the sides of the head red ; the bill horn ; the feet and toes sepia. 



An attempt should be made to preserve, however crudely, together 

 with pertinent data, any lineated or silver pheasant shot in Thailand, 

 as an aid to solution of the perplexing problems of distribution of 

 the various forms. 



The adult male has the crown and long crest black with a greenish 

 or bluish gloss; the remaining upperparts finely vermiculated black 

 and white, giving a slaty-gray appearance; the inner webs of the 

 central tail feathers almost wholly unmarked white; the underparts 

 black with scattered white shaft streaks, which are broader and more 

 numerous at the sides of the body. The adult female has the upper- 

 parts golden-brown, with V-shaped white or buffy marks on the neck 

 and upper back, white or buffy shaft streaks on the rest of the mantle ; 

 the tail beautifully barred and mottled with black, white, and red- 

 brown ; the throat plain light brown ; the remaining underparts mixed 

 rufous and dark brown, with broad white shaft streaks everywhere. 



I have elsewhere given my reasons for the adoption of the specific 

 name crawfurdii (cf. Diegnan, Auk, 1943, pp. 88-89).
