Though the large number of birds peculiar to Ceylon shows that it 

 has probably been separated for a long period, yet the resemblance 

 of its avifauna to that of Southern India is so strong that it does 

 not bear out Sir J. E. Tennent's belief that it originally formed part 

 of a lost Malayan continent. 



Only four species belong to genera not found in S. India ; and it 

 is quite possible that, when the extreme south of the peninsula is 

 better known, even these may be found. The occurrence of Arrenga 

 is very remarkable ; for, as far as we know, the only other species 

 referred to that genus is peculiar to the mountains of Java ; and 

 though nearly allied to Myiophonus, which is found in all the 

 mountains of the Indian region, yet the generic distinction is suffi- 

 ciently well marked. I will here mention some of the genera found 

 in Ceylon which are remarkable on account of their distribution : —
