DUTCH BORNEO-EXPEDITION. 267 



the Malay Peninsula to Sumatra, Banka, Borneo and the 

 Philippines. 



I feel obliged, after a close comparison of all the ma- 

 terials in the Leyden Museum, to unite T. nasica Schleg. 

 with T. nipalensis Hodgs. "When describing T. nasica, Schlegel 

 was not acquainted with T. nipalensis Hodgs., and in his 

 Catalogue of Columbae, p. 55, he declares that T. nasica 

 seems to differ from T. nipalensis only by its smaller size, 

 but comparing the sizes of both species as stated by Sal- 

 vadori in the Catalogue of Birds mentioned above, I cannot 

 find any noteworthy difference. Salvadori, in his Catalogue 

 says that the Malayan birds are smaller and duller than 

 those from Nepal and Tenasserim, but these differences do 

 not hold well in the numerous specimens before me.
