Some specimens have the entire flanks dingy greyish, 

 while others are strongly ochraceous fulvous. All have the 

 wing in the neighbourhood of 60 mm., and there is much 

 variation in the white tips to the secondaries and their 

 coverts. 



It is unfortunate that Mr. Stuart Baker has apparently 

 compared his form with races from the north with which he 

 is more familiar rather than with C. b. leucosticta Sharpe, 

 wliich is the nearest geographical race. Had he done so 

 on sufficient series, we are convinced that he would have 

 refrained from describing it, 



Personally, we consider that, excluding Corythocichla 

 crassa (Lanioturdinus) from Borneo, which is fairly distinct, 

 all the described races of this genus are no more than 

 geographical forms of the oldest named form, viz., C. brevi- 

 cuudata (Blyth). Cory ihocichla ca.u, in our opinicm, be con- 

 veniently retained as a distinct genus and not united with 

 Turdinulus, as has been done by Hartert and Harington.

This race is of even more doubtful value than the pre- 

 ceding. We have examined the types [vide Herbert, Journ. 

 Nat. Hist. Soc. Siam, ii. 1916, p. 58) and compared them 

 with specimens of the true S. r. polioff aster, with which 

 they agreed, being exactly matched by a male collected at 

 Ginting Bidei, Selangor, .^SOO', on 10 May, 1909 (F. M. S. 

 Mus., No. 1304/09). The form is wide spread, though every- 

 where extremely rare, and no separation siiould be attempted 

 except on very much larger series than are at present avail- 

 able, in view of the known liability to change of tint in all 

 Timeliine birds from age of skin after death. 



The original type of S. r. poliogaster was from Gunong 

 Pulai, Johore. We possess specimens from Selangor and 

 Perak in the Malay Peninsula, and from Korinchi in western 

 Sumatra ; while it has also been recorded from central 

 Borneo.
