Micropternus brachyurus iv ill iamsoni, IbiS, 1918, p. 107 (Koli Liik, 

 S. W. Siaiu). 



This form probably ranges over the whole of Soutli Teiias- 



serim and S. W. Siam and grades into : — 



(e). Micropternus brachyurus burmanicus Hume. 



Micropternus burmanicus, Pioc. Asiut. 8oc. Bengnl, 1872, p. 71 

 (Tluiyetmyo, Pegu). 



Still larger, with markings more reduced. 



This race probably occupies all Siam, north of Bangkok, N, 

 Tenasserim and the Shan States, South and Central Burma, and pos- 

 sibly Arracan (wing 129 mm.). North (jf this area is found: — 

 (f). Micropternus brachyurus phaeoceps Blyth. 



Micropternus phaeocej)s, Jouni. A.siat. Soc. Bengal, xiv, 1849, p. 19.5 

 (Neighbouiliood of Calcutta 1 ). 



This race is smaller on the whole than burmanicus, less im- 

 maculate, more rufous on the shafts of the primaries and tail 

 feathers. Range — Bengal and Assam, meeting the preceding in the 

 Soutli and East : M. brachyurus mesoti in the South-west : and in the 

 North-west : — 



(g). Micropternus brachyurus blythi (Malherbe). 



Phaiopicos BlythH, Rev. k Mag. Zool. (2) i, 1849, p. 534 (Nepal). 



Because authors have been unable, or have omitted, to refer 

 directly to Malherbe's own writing, there has been a good deal of 

 confusion about this race which, however, was cleared up by Hesse 

 in 1912 (Mitt. Zool. Mus. Berlin, vi, 1912, p. 195 et seq.). 



Malherbe first called the race Picus rufinotus in 1844, but 

 gave no description : hence the name is invalid. In 1849 (I. c. s.) he 

 described the bird and renamed it FJtaiopicus Blyfhii : " d^diee au 



savant directeur du Museum de Calcutta, habite le Nepaul Elle 



a 6t6 apportee par M. Hadgson " (Hodgson). Still later he withdrew 

 blythii and again called the race rufinotus " Le Plmiopic rufinote 



1 The actual types of this form are a male and female collected by 

 E. Blyth in 1844 in the neighbourhood of Calcutta.
