We are in fair agreement with Mr. Baker's discussion of the 

 species, but we cannot admit that the south Indian and south 

 Malayan Ijirds are identical, separated as they are by the intervening 

 subspecies ;S'. g. guttacristatus. The southernmost known specimen 

 of G. g. guttacristatus is a female collected by Robinson at Biserat, 

 Jalor, in Pattani on June 29th 1901. South of that, until we reach 

 the extreme south of Johore, the bird has never been met with, 

 though the area has probably been as well collected over as any
