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. 



33. SCLEROPTERA GUTTURALIS (Ruppell). 



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 rioriken with yellow iris, called by the Somali IVaradada. 

 When frightened, it flies off^, uttering a loud cry like ka-ki-rak,

 mandible.

 Irides light straw-yellow. In almost all particulars of habit 



it corresponds with the common Indian bird of the same size.

I found these birds also on the lakes south of the equator.

 gaster, Cuv., Par. Mus.) 



A common sea-bird, which I shot at Bunder Goree.

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 neighboui'hood 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
