This only differs from R. undulatus in smaller size, in having no dark bar across the yellow or blue throat, and especially in the sides of both mandibles being smooth, there being no trace of the grooves that are found on the bills of adult R. undulatus.

Length of males about 34 ; tail 10 ; wing 16.5 ; tarsus 2.1; bill from gape 7. Females are smaller: length about 30; wing 14.5; bill 6.

Distribution. Arrakan, Eastern Pegu, and Tenasserim, more common from Moulmein to Tavoy than farther south; also Sumatra and Borneo, and probably the Malay Peninsula.

Habits, &c. Similar to those of the last species except that, according to Bingham, this is less of a hill bird. It is generally seen in large flocks, flying low. Oates found birds of this species feeding on snails on the ground in an open plain. Tickell noticed Hornbills of this or the last species bathing in a river in the evening. The eggs have been taken in Pegu and Tenasserim at the end of February and in March ; the nest-hole is usually on very high trees and at a great height from the ground, the number of eggs one to three and the size about 2.29 by 1.61.
