plumage dull brownish mouse-colour. The quills are not fringed as in the male. ‘The 
bill in this species is built on the same model as that of 2. panini; but there do not 
appear to be as many grooves in the maxilla, five being the greatest number apparent. 
In a very old male (no. 6), judging by the bill, several new rectrices have come, 
which have the central band almost white, the colour above and below this band being 
black glossed with green, and not brown. The remaining old rectrices are as described 
above. In avery old female example (no. 7) the same peculiarity is to be found. A young 
male (no. 5) with the casque partially developed, but without lateral plates or grooves, 
has the rump ferruginous, and the first-plumage rectrices broadly washed with ferru- 
ginous at their apex. 
Meyen (/.¢.) most positively stated that this Lucon chiselled-billed Buceros did not 
belong to that of Panay; and he gave an accurate figure of the old male.

Dr. v. Martens (J. f. O. 1866, p. 18) enumerates as an additional species of Philip- 
pine Hornbill an individual observed by him in the Military Library at Manilla. He 
describes it as being without a casque, and as haying the tail long, the head crested, the 
bill and face black, the nape pale yellowish brown, the back and wings spotted and the 
under surface yellowish. Dr. vy. Martens suggests that it may be B. gingalensis, Shaw, 
and bestows no title. The description above given does not agree with the Ceylon 
species, and was probably made from an immature example of one of the foregoing 
species.
