 certain spots on river banks to drink, and after taking a draught

C. viridifrons Bl., of Pegu and Tenasserim, is another nearly 

 affined race of Crocopus, chiefly differing from C. phcvnicopterus, 

 which it very closely resembles, by its conspicuous green forehead,

 maronne colour on the back, the other colored much as in Treron.
