It will thfirrort" l)r luuud that the total number of species of 

 hirds found in Siaiii will vastly exceed the corresponding lists for 

 the Malay I'euiiisula, jSuniia, and other surrounding countries, and 

 will i)i()l)il)Iy he not nuich less than 1,200-1,300 species. Of late 

 ye ir.s much ornithologicil work has been done in Siani by Williamson, 

 (lairdiier, Herbert, Gyldeustolpe, Eiscuhofer, Darton and ourselves, 

 and a considerable anunint of literature on the subjeL't has been 

 published. No exhaustive faunal and regional lists have as yet been 

 issued, with the exception of a List of tlie Birds of Eangkok by 

 Williamson i, and a general list of the Birds of Siam by Count Nyls 

 CJyldenst )lpe '^, and we hav^ therefore thought it well to publish a 

 full and detailed aec:nuit of the birds of S. W. and Peninsular 8iam, 

 which we have defined as the portion of Siam south of the head of 

 the Gulf of Siam. As regards Peninsular Siam — that portion of the 

 ountry sjuth of the Isthmus of Kra or Pakchan river — Ave can claim 

 that (»ur list is almost complete: excluding Avhatever new forms 

 may bj found in the Nak )rn range, no new additions are likely to 

 bj made other than cisual migrants, small owls and frogmouths, and 

 other noL-turnal birds whose capture is always a matter of chance, and 

 common southern Malayan birds of which actual specimens, for some 

 reiso.i or other, may not be in the possession of our own or other 

 musL'uins. For the n )rthern portion of the area, from the Gulf of 

 Siam to the Pakchan river, i. e., S. W. Siam, we do not claim any such 

 completeness, though even in this section we do not think that tlie 

 nund^er of species that will ultimat.dy be added to the list will prme 

 large or of great importance. 



Some statement may be given as to nuxterial on wdiich this 

 I)ape,r is ffjunded. Since 1901 one or other, or both of us, as well as 

 parties (jf the collectors attached to the F. M. S. Museums, have collected 

 over the southern portion (jf the area, and the collections made have 

 munbered several thousand skins. A considenible number of these are 

 in the Biistish Museuui ( Nat. Hist.), South Kensington, and a few 

 at Tting, but the bulk remain with us and must outnumber very
