• a. t Ponsee, 21st April 1868. 



I have two specimens before me from England, with which my Yunnan bird 

 agrees in every particular. Dr. Jerdon has remarked that the under tail-coverts of 

 C. canorus have distinct arrow-shaped markings, hut in the specimen before me, 

 they are barred, but more widely so than on the breast, &c. 



We first heard the Cuckoo at Ponsee, about the end of March, and its well- 

 known notes were usually traced to some patch of low tree-jungle on old paddy 

 clearings, on the hillsides overlooking our camp.

I have observed specimens of C. rufiventris, in which the rufous passes as far 

 forwards as the chin, and others in which the ashy of the breast spreads back on to the 

 rufous of the abdomen.
