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 7. nasica Schleg. 
with 7. nipalensis Hodgs. When describing 7. nasica, Schlegel 
was not acquainted with 7. nipalensis Hodgs., and in his 
Catalogue of Columbae, p. 55, he declares that Z. nasica 
seems to differ from 7. 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.
