raised, and its head and body moving in all directions. Be- 
sides fruit, this bird must eat orthopterous insects, as the 
wings and other parts of Grylli were found in their stomachs. 
In this family the first and fourth toes are directed laterally, 
and, as befits birds feeding chiefly on fruits, the stomach is 
very large ; some of the species are very shy, such as Bur- 
chelFs Touraco [Corytliaix porphyrGoloplia), from Port Natal, 
w^hich, unlike some of the others, as Dr. Andrew Smith tells 
us, remains motionless when conscious of danger ; and as, 
like the rest of the family, its usual position is parallel to 
the branch on which it rests, its generally green colour keeps 
it from being seen. 
The Hornbills (Bucerotid^) are African and Asiatic birds, 
generally of considerable size, with enormous beaks, toothed 
on the edge. The beaks are often surmounted by a protu- 
berance, which, in many cases, is as large as the bill itself. 
S. Miiller and Schlegel have published a monograph of thern^, 
and described some new species. Miiller tells us that the
