By E. C. Stuart Baker, f.l.s., f.z.s., c.f.a.o.u., m.b.o.u. 

 (Continued from page 443, Vol. IIIj. 



The present part concludes the catalogue of Mr. Herbert's 

 collection of birds. The number of species and sub-species enumer- 

 ated is 295 and of these 11 are new forms, whilst many others 

 have been now. recorded for the first time from Siam. 



The forms described as new are : — Eupetes maerocercus 

 griseiventris ; Pomatorhinus olivaceus siamensis ; P. nuchalis 

 klossi ; Stachyridopsis rufifrons obscura ; Cyanoderma erythrop- 

 terum sordida ; Dicrurus leucophaeus disturbuns ; Prinia inornata 

 herberti ; Grauccdus macei siamensis ; Oyornis magnirostris 

 coerulifrons ; Thereiceryx lineatus intermedins ; Alcedo meninting 

 scintillans. 



In addition to the above I have also found it necessary to 

 describe many new forms from other parts of the Oriental Region } 

 whilst comparing various series in comparison with those contained 

 in this collection. 



Unfortunately, as Mr. Herbert has explained in the first 

 part of this catalogue, I have been considerably handicapped by 

 my want of knowledge of the local geography, and have sometimes 

 been led astray by the similarity, or mis-spelling, of names from 

 widely different localities. Such deductions as are wrong on this 

 account - or any other - 1 propose, if our Editors will kindly allow 

 me, to correct fully in a further note on Mr. Herbert's collection. 

 In this I shall also be able to deal with those points in which 

 Messrs. Robinson and Kloss have been unable to agree with my 

 conclusions. 



There are, however, one or two mistakes it may be as well 

 to correct at once. 



Alcippe phwocephala davisoni Harington. This is quite a 

 good sub-species. It is true that the markings of the head are of 

 no use as a character in differentiating between A. p. magnirostris 

 and A. p. davisoni, but the tint of the upper plumage is quite 

 distinct and suffices to distinguish between the two. Since I wrote
