The female from Lat Bua Kao, where otherwise only A. r. 

 richardi was met with, is a trifle larger than the Koh Lak 

 birds and rather more richly coloured above, with throat and 

 underparts more fulvescent, but I do not think it can be 

 other than a member of this race. The outer web of the 

 penultimate tail-feather is black, while in the others it is 

 white, but, as Sharpe has stated (Cat. Birds, x. p. 577), this 

 is a peculiarity that frequently occurs in birds from the 

 Malay Peninsula ; and in a series collected south of 

 Lat. 10° N. 1 have found that many birds possess this 

 feature and show a considerable degree of variation in the 

 amount of white on the inner web also. 



A. r. striolatus Blyth does not seem to occur in the Malay 

 Peninsula ; of all the Pipits 1 have seen from there, one 

 (apparently abnormal, though adult and fully plumaged) 

 has a wing of 71 mm. ; thirty (two of them much worn and 

 bleached) have wings between 75 and 80 mm., and the 

 wings of twelve (four much worn and bleached) range 

 between 80 and 84 mm. 



On the supposition that A. r. rufulus is confined to western 

 and central India with Ceylon, whence I have no specimens, 

 I have used Eyton's name for the Indo-Chinese and Malayan 

 birds.

This bird has not been met with so far south before, 

 though it is common at Bangkok; a pair obtained there 

 by Mr. W. J. F. Williamson have wings of 84 and 82 mm.
