Most authorities are agreeci t hat in the Indian and Indo- 

 Malayan regions two races occur, viz., one with a wing less than 

 8 in. (200) mm. and a less robust bill, the male with a greenish 

 gloss and the female with clear white streaks on the head and 

 white bars on the tail. 



This race is Eudynamis orientalis honoraia (Linn.) 



The second race is larger, wing up to 8.6 in. (215 mm.) or 

 more, with a more robust bill, with a cast of violaceous in 

 tlir plumage of the male and the pale parts of the female buffs 

 or rufescent buff. 



This race is Eudynamis orientalis malayana, Cab. and 

 Heine. 



Judged by these standards specimens from Trang 

 1 Mainland and Islands), December and January; Koh Pennan 

 and Koh Samui, SW. Siam, May; Pulau Langkawi, February; 

 Pulau Paya near Pulau Langkawi, December; Pulau Jemor, 

 Aioa Ids. November; Pulau Jarak, Straits of Malacca, March; 

 and Pulau Lalang and Pulau Kumpia, Sembilan Ids., November 

 and January; belong to this form, Eudynamis orientalis malayana, 



I ab. and Heme while others from Pulau Langkawi, February; 

 Pulau Paya near Pulau Langkawi. April; Pulau Bidan, near 

 Penang, April; Pulau Jarak, Straits of Malacca, March; Pulau 

 Rumpia, Sembilan Ids. January and March, and Great Redang 

 Id. off the coast of Trengganu, August, belong to Eudynamis 

 orientalis honorata (Linn.). 



The evidence, such as it is, points to the possibility that 

 there is no resident Koel in the Malay Peninsula, south of 

 Trang, and that the birds that are so numerous on the small 

 islands off the coast are seasonal visitors, the differences noted 

 between them being due to the fact that they have come from 

 widely separated localities, thus accounting for the fact that 

 two apparently different races can be shot on the same small 

 island on the same day. The racesof Eurystomus orientalis and 

 Accipiter gularis afford parallel instances.
