Genus GARRULAX, Lesson, 1831. 



The genus Garrulax differs from Dryonastes in having fewer 

 bristles and hairs covering the nostrils, the number being 

 so reduced that the nostrils are clearly visible. The species of 

 Garrulax are on the whole much larger birds, and some of them 

 have very ample crests. 



The colour of the egg is known in five Indian species of Garrulax 

 out of a total of nine. Of these five, three lay blue eggs and two 

 white. I cannot, however, discover any external structural cha- 

 racter by which those laying blue eggs may be separated from those 

 laying white ones. Some better distribution of the birds may 

 become possible when the eggs of the remaining four species are 

 known.
