192 PORPHYRIO BEMMELENT. 



fers from both by the blue (instead of purplish) color of 

 sides of chest, breast and flanks, and from the latter spe- 

 cies , with which it is related by its dark green color of 

 back and wings, by the sea-green instead of turquoise 

 blue color of the lower throat and chest.

 Bemmelen , who rendered already so many important ser- 

 vices to Ornithology , may be described as follows :

 more or less broadly margined and tipped with blue. Quills
