This Hornbill was described by Temniinck in his Planches Coloriees, but not figured ; and the 

 female was also given in the same work as a distinct species under the name of Buceros gracilis. 

 It is a native of Malacca, Sumatra, and Borneo, very rare in collections ; and nothing is known 

 of its economy or habits in the wild state. A specimen living in the London Zoological Gardens 

 was stated by Mr. Sclater (I. c.) to have the end of the tail-feathers white instead of rufous ; I have 

 also noticed this as occurring in occasional specimens, but am inclined to regard it as only an 

 individual peculiarity, as the majority of the examples that I have seen have had the end of the 

 rectrices rufous or light chestnut. Salvadori, in his fine work on the Birds of Borneo (L c), states 

 that the male of this species has the bare skin of the throat canary-yellow, and the iris dark red, 

 while the iris of the female is yellowish brown. 



In the 'Proceedings of the Zoological Society of London' for 1869, Mr. Bartlett gives an account 

 of the sac, containing undigested food, cast up by a Hornbill of this species, at that time an 

 inmate of the Gardens in Regent's Park. This curious object was submitted to Dr. Murie for 

 examination, who ascertained it to be simply the " thickened semichondrified lining membrane 

 of the gizzard. All the puckerings and indentations were more or less exactly represented, though 

 less sharp in outline than is ordinarily the case. The mucous surface of the inner wall of the baa- 

 was slimy, otherwise perfectly identical with the same structure in a healthy bird. The surface 

 outside, on which might be said to be the submucous tissue, was moist, comparatively uninjured,
