NOTE ON TRIBURA MANDELLII. 241 



collection, and not one has the slightest indication of spotting ; 

 neither is there any indication of the ash grey so conspicuous 

 across the breast of T. mandellii. T. mandellii, as a rule, has a 

 stronger and larger bill, and most of the bills are more or less 

 black, as in ajjinis. 



The lower surface of the body is very much more rufous 

 in luteoventris than in mandellii. 



After a very careful comparison of the two birds, with ample 

 material before me, which Mr. Seebohm bad not, I have not the 

 least hesitation in stating mandellii to be perfectly distinct. 

 The dry skins to me will not prove anything else, and the two 

 could not be correctly united but by observation of the birds 

 in life. It is a pity that all Mandelli's birds are unsexed ; for 

 he never collected himself, and his native collectors were not 

 able to sex correctly. Had they been reliably sexed, and all the 

 spotted T. mandellii had turned out to be males, while all the 

 unspotted and more rufous luteoventris turned out to be females, 

 there would then have been some reason in Mr. Seebohm's very 

 decided conclusion that my species was a bad one. As it is, 

 he has only begged the question, and can, in no way, prove his. 

 point, any more than he can that Phylloscopus viridanus and 

 P. plumbeitarsus are one and the same bird — -a mistake only 

 equalled by my own some years ago that P. tristis was identical 

 with P. collybita. 



Mr. Hume has been accustomed to term T. mandellii D. 

 brunneipectus, Blyth ; but I think this is wrong ; for Blyth 

 describes his brunneipectus as being of the same uniform dark 

 olive brown colour above as D. affinis, and our present bird 

 being very different above from D. ajffinis, and of a much lighter 

 and rufous brown as in luteiventris, Blyth's term could not, 

 I hold, apply to it. 



An examination of Blyth's type would decide the question, 

 and this examination I hope soon to be able to make. 



Blyth does not make any mention of spots on the breast, and 

 these appear to be characteristic of T. mandellii.

Since the publication of our first list, (S. R, V., 1, 1877), 

 Mr. Inglis has from time to time kindly sent additional speci- 

 mens, representing species not formerly included, and some 

 of them of considerable interest. 



The first list comprised 157 species. We have now 100 more 

 species to add (making a total of 257), and a few additional 

 remarks to add in regard to one or two species previously
