slioulfler and take food from his lips. It is a curious fact 

 tliat its low and long-drawn note so exactly resembles that 

 of a young Situtunga [Tragelaphus spekei) that it is almost 

 impossible to tell them apart.

Iris dark brown; bill black; feet greenish-grey. 



This Cuckoo was commonly met with on the Molopo River, 

 occasionally in the Kalahari, and again in iS'gamiland. It 

 was ahvays rather a shy bird and difficult to approach.

This Hornbill was found plentifully on the Molopo River 

 and in Ngamiland. It was occasionally seen in the Kalahari, 

 but never at any great distance from water. The birds 

 have a wonderfully buoyant flight : they will launch them- 

 selves from the top of a tree and glide for a long distance 

 without moving their wings ; when they sink too low they 

 give a few slow flaps and then glide on again till they alight 

 clumsily on another tree. There are often several of them 

 together. They have a very curious but musical piping 

 note, which they utter sitting bolt upright on a bough, with 

 the neck fully extended, and the long bill pointed straight up 

 to the sky. I have seeu tAvo calling simultaneously side by 

 side and looking perfectly ridiculous.
