SIVA SORDIDIOR SORDIDIOR Sharpe 



Siva sordidior Sharpe, Proc. Zool. Soc. London, 1888, p. 276 (Batang Padang 

 Mountains, Perak). 



One male and three females, Kao Luang:, 3,000-4,000 feet, Nakon 

 Sritamarat, Peninsular Siam, July 14-20, 1928. 



Robinson and EHoss ^° have assigned Kao Nawng, Bandon, and 

 Kao Luang, Nakon Sritamarat, specimens to Siva cyanouroptera sordi- 

 dior Sharpe described from the mountains of Perak, but they say the 

 identification is doubtful, as the specimens upon which the records 

 rest are in bad shape. They say also that sordidior is not very 

 strongly differentiated from S. c. sordida Hume. I have not been able 

 to examine a specimen of the latter, but sordidior in my opinion is not a 

 form of cyanouroptera at all, but a distinct species of which orientalis of 

 southern Annam is a form. 



S. s. sordidior and S. s. orientalis differ from the cyanouroptera forms 

 in lacking the white superciliary; in having blue of pileum dull and 

 very barely perceptible in certain lights; outer margins of inner 

 primaries and all the secondaries almost white or barely tinged with 

 bluish; white on the inner margins of the outer tail feathers, more 

 restricted; blue of tail dull and showing only in certain lights basally; 

 tail slightly darker grayish brown like the back. 



S. s. sordidior ranges from the mountains of the Malay States north 

 to Bandon.

(Nepal). 



One female, Bo Ploi, Kanburi, September 26, 1929; two females, 

 Doi Nangka, April 25, 1931; one male, Doi Hua Mot, August 27, 

 1934; one male, Khun Tan Mountains, 3,000 feet. May 10, 1933; 

 one female, Khun Tan, August 29, 1930; two males, Aranya, July 16, 

 17, 1930; two males, one female, and one unsexed, Pak Chong, Febru- 

 ary 17, May 9, and November 15, 18, 1925; one male, Tlia Chang, 

 Pak Chong, March 22, 1927; three males. Lam Klong Lang, near 

 Pak Chong, June 3-14, 1925; one male and two females Hin Lap, 

 December 9, 11, 1931; one male, Lamton Lang, June 1, 1934. 



Quite a number of the above specimens have slight remains on the 

 back and nape of an earlier plumage, which is tawny-olive and mixed 

 in with the yelloM^sh citrine of the succeeding plumage. It occurs 

 on specimens taken from May 10 until the latter part of August, but 

 there is one specimen collected as early as March 22, and another 

 collected April 25, -svith the nape tawny-olive. The latter (no. 

 330550), from Doi Nangka, has the lores and a ring around the eye 

 massicot yellow and is unique in the series in this respect.
