 Tr. Z. S. viii. agreed with the type as described by Teinminck. But it seems possible that the absence and 

 P- "*'• presence of the white frontal spots only denote phases of plumage. If not, the Indian bird will 

 belong to a different species, while tlie Celebean may be cither the same as tlie Indian (in itself 

 highly improbable), or represent a third form.

The male is distinguished from the female by having the throat, cheeks, ear-coverts, sides 

 of neck, and superciliary stripes springing from base of mandible white. In my examples the 

 white supercilium has light ferruginous-brown feathers intermixed. In dimensions the female 

 appears to be somewhat smaller. The example I note from is marked by the collector "female," 

 while the entirely black individuals are marked " males." According to Professor Schlegel (/. c.) 

 the subject of Temminck's plate was a female ; and, together with Salomon Miiller, he describes 

 the male as having the throat and sides of the head white. 



As this curious form does not belong to any of the established subdivisions of the family, 

 I leave it for the present in the old Linnican genus. It is certainly not a Hijdrocissa, as classed 

 by Prince Bonaparte. It belongs to the group of Ilornbills in which the casque and the true 

 maxilla are completely blended together, the prolongation of the casque forming, in old birds, 

 the apex of the maxilla.
