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 Tenasserim. The Sumatran 

 Koel is likewise regarded as distinct by Dr. Cabanis, and will probably 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 com- 

 parison 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 E. ransomi, Bp., from 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 com- 

 pare Javan with Sumatran specimens ; but it is probable that the races from the two islands will 

 Ibis, 1869, be found to differ. From the bill being so conspicuously large, I strongly suspect that Javan 

 ^' ^^^' examples furnished Lc \'aillant with the subject of his " Coucou a gros bee," plate 214, in which 

 case it would stand as E. crassirostris (Steph.).
