The common Koel of India, the lower ranges of the Central 

 and Eastern Himalayas excepted. Out of a large series of Ceylon 

 specimens I have not found one that differed in the least from 

 the Peninsular bird. The eastern range of this species is not 

 satisfactorily determined; but I question whether it crosses the 

 Brahmapootra.

A Koel closely allied to E. honorata, as I restrict it, but 

 larger in all its dimensions, and with a conspicuously longer and 

 stouter bill, inhabits Nipaul and Tenasserira. The Sumatran Koel 

 is likewise regarded as distinct by Dr. Cabinis, and will pro- 

 bably be found to agree with the species from the localities I 

 have named. Dr. Cabanis states that the Sumatran bird is 

 larger, but that in all other respects it is the same as E. honorata 

 as above. But a rigid comparison of a large series of specimens 

 has yet to be made before the latter part of this assertion can 

 be taken for granted. Indian Ornithologists might greatly 

 assist us by studying and recording the phases of plumage the 

 Koel passes through before arriving at maturity. 



These are the principal dimensions of the Indian, Javan, and 

 Australian species : —

Javan examples are remarkable for the length and stoutness 

 of the bill ; with a shorter wing and tail than in E. ransomi, 

 Bp., fi'om Ceram,the bill is larger and deeper in the Javan bird. I 

 have not seen specimens in the female or adolescent male 

 plumage, nor have I been able to compare Javan with Suma- 

 tran specimens ; but it is probable that the races from the two 

 islands will be found to differ. From the bill being; so con-
