Mr. Davison saw the bird, but failed to secure specimens, at or near the 
same locality. 
This Hornbill has been met with in Cachar and the hill-tracts of Eastern 
Bengal, and it ranges along the Himalayas to Nipal. 
Mr. Gammie found the nest with a solitary egg in Sikhim in May, 
situated in the hollow of a tree at a great height from the ground.

upwards; Cranorrhinus corrugatus, from the Malay peninsula, with the 
terminal half of the tail chestnut ; Tockus griseus and T. gingalensis, from 
India, both of a brownish colour and with no casque on the bill ; and 
Lophoceros birostriSj also from India, with a sharp-pointed and projecting 
casque.
