100 EOLLULUS.— CALOPERDIX. 



Genus ROLLULUS. 



Remarkable for wanting the claw of the hind toe. From their colour, fan-like 

 crest, and different colour of the sexes, they might rather he placed with the 

 Jungle-Fowl than with the Partridges. The crest is similar to that of the Crowned 

 Pigeons, and the bare frontal plumes are only represented elsewhere in this family 

 by some of the American Partridges (Jerdon, iii. p. 580). Placed by Gray in 

 TetraoniruB. Called by Blanford "the Green Wood-Quail." Long hair-like 

 bristles on forehead in both sexes. Male with full crest. Tail of twelve feathers 

 about two-fifths length of wing. First primary equal to tenth (fifth longest). 

 Claw on hind toe rudimentary or wanting. Naked eye-patch. No spurs.
