But the study of the reversed under coverts will have to 

 be carried much further before conclusions bearing on the 

 classification of birds can be safely derived therefrom. 



In conclusion, the author of this paper is glad to acknow- 

 ledge the encouragement, advice, and help received from 

 Mr. W. R. Ogilvie-Grant in the putting together of the 

 records of his observations in a form for publication. The 

 observations themselves were made quite independently and 

 alone, the idea of making them having been derived from 

 reading Mr. Pycraft^s paper referred to in the introduction, 

 and afterwards that of Sundevall. 



XXIX. — Notes on recently described Races of Siamese and 

 Malayan Birds, with a Description of one new Race.

Within the last few months a considerable number of 

 races of Malayan and Siamese birds have been described in 

 various periodicals, English and Foreign, by E. C. Stuart 

 Baker, Count Nyls Gyldenstolpe, Dr. E. Hartert, H. Ober- 

 holser, and Lord Rothschild. 



As the collections of birds from these regions that are 

 either embodied in the collection of the Federated Malay 

 States Museums, and collected by us, or have passed through 

 our hands, are very large indeed, while in some instances 

 the races are actually founded on duplicates from our col- 

 lections, some remarks on certain of these species may 

 possibly be of interest. 



In the first place, it may not be amiss to observe that in 

 some cases a certain laxity is apparent in the quotation 

 of precise type-localities, though this, of course, is not 

 entirely to be laid to the door of the describer. Localities 

 which are quite familiar to the original collector, who in 

 many cases may have collected entirely for his own edifica- 

 tion, and which may even be readily traceable by local 

 residents, are very frequently not to be found in any map at
