1918.] described Siamese and Malayan Birds. 589 



Stuart Baker records the range of this form as extending 

 to the extreme south of the Malay Peninsula, but in this he 

 is not correct; birds from the south of the latitude of Trang 

 are all to l)e referred to tlie typical lole olivacea Blyth, 

 Journ. Asiatic Soc. Bengal, xiii, 1842, p, 386, which differs 

 in being much browner, less greenish olive, with the throat 

 greyish white, and the belly tinged with sulphur-yellow; 

 axillaries with no tinge of buff; under tail-coverts dull 

 brown with paler edges ; bill larger and wing 86-90 mm. in 

 birds from the Malay Peninsula, 85 mm. in a female from 

 eastern Sumatra. 



All these forms stand in subspecific relationship to each 

 other, the meeting-place of lo/e olivacea olivacea and lole 

 olivacea virescens being about in the State of Trang, whence 

 we have also a female of the former race, wing 87 mm. 



A female from Meetan, Mt. Mooleyit, north Tenasserim, 

 measures 81'5 in wing, and appears to agree with the north 

 Siamese bird described as Criniger lonnbergi Gyldenstolpe, 

 Kongl. Sv. Vet.-Akad. Handl. 1. No. 8, p. 24, pi. i. fig. 1. 



The fornjs therefore are : — 



1. /. olivacea olivacea Blyth : Sumatra, Borneo, Java, 



British portion of Malay Peninsula. 



2. /. olivacea cinnamomeoventris : Peninsular Siain to 



Tenasserim. 



3. 7. olivacea lonnbergi : Central Tenasserim and north 



Siam. 



4. /. olivacea virescens : Aracan, central and southern 



Burma. 



f Pomatorhinus olivaceus siamensis.

This race froui Maprit, south-western Siam, should cer- 

 tainly have been compared with that described as Fumatu- 

 rhinus schisticeps fastidiosus, Hartert, Bull. B. O. C. xxxvi. 

 1916, p. 81, from Trang and Bandon, peninsular Siam, less 

 than 200 miles distant. 



We have seven specimens from Kao Nong, Bandon, and 

 three from various places in Trang, peninsular Siam, which 

 we have compared with two specimen* from Me Wang,
