IS bo. 
31. Pternistes rubricollis (Latham). 
Common Somali Partridge, called by the natives Digrin. It 
runs like the red-legged bird, and is very hard to kill; but the 
flavour of its flesh is good, even better than that of any other 
game in the country, and repays one well for the trouble of 
shooting it. 
32. SCLEROPTERA GUTTURAL1S (Riippell). 
I shot this Partridge on the mountain, and could not hear of 
its existence anywhere else. 
33. Sypheotides humilis, Blyth, Journ. As. Soc. Beng. xxiv. 
p. 305. 
A Floriken with yellow iris, called by the Somali JVaradada, 
When frightened, it flies off, uttering a loud cry like ka-ki-rak, 
ka-ki-rak. I found it here on the Plateau amongst low herbage 
and grass, but not so numerous as I subsequently did in Central 
Africa, south of the equator. The male is smaller than its mate, 
and has black feathers, which distinguish it, under the lower 
mandible. 
34. CEdicnemus affinis, Riippell. Somali, Kedinliitu. 
Irides light straw-yellow. In almost all particulars of habit 
it corresponds with the common Indian bird of the same size. 
35. Chenalopex /Egyptiacus (L.). Egyptian Goose. So¬ 
mali, Etal-Jaz (“who lives at wells ”). 
I found these birds also on the lakes south of the equator. 
36. Phalacrocorax lugubris, Riippell. {Carlo rnelano- 
gaster , Cuv., Par. Mus.) 
A common sea-bird, which I shot at Bunder Goree.

phasis derbianus). By Osbert Salvin, M.A., F.Z.S. 
Though some years have elapsed since the discovery of this 
strange bird, little or no additional information has been given 
as regards its habits and economy. Having resided for several 
months in the neighbourhood of its only known locality, I shall 
offer no apology for entering somewhat at length upon the few 
facts that I have been able to pick up, relating both to the
