is rather rare. At Port Achard it is found in abundance, and is 
used by the natives to make necklaces of, or strung in clusters round 
their waist in their war-dances. It is always found in company with 
Helix merziana and H, eleryi. The most northern limit of it is 
Sesarga or Contraietés, the southern limit is San Christoval. Spe- 
cimens vary much both in colour and in size. 
5. On the Genus Chetops. By R. B. Suarpr. 
(Plate XIV.) 
The genus Chetops was founded by Swainson in 1831, and up to 
the present time contains only two species, viz. C. frenatus and 
C. aurantius. In a collection of birds formed in Damara-land by 
the late Mr. C. J. Andersson, I met with a species of Chetops which 
I have every reason to believe is new to science. On taking my 
specimen to the British Museum I discovered another in the na- 
tional collection; and my friend Mr. George Robert Gray coin- 
cided in my opinion as to its novelty. He had, indeed, noted it as 
new, and intended to describe it himself shortly, I have therefore 
very great pleasure in naming this species

either of the species hitherto known; and the following diagnostic

The following account of the habits of this rare bird is taken from 
Mr. Layard’s work (oc. cit.) :— 
“This bird is, as far as I yet know, peculiar to the mountain- 
ranges between Caledon and Swellendam. It frequents the tops of 
the hills and high elevations on their stony sides, and seeks its food, 
consisting of insects, about stones and rocks. In habits it much 
resembles the Rock-Thrush, and, like it, is fond of perching upon the
