[Dodsou's Thick-knee is not uncommon in the sandy wadis whcrc^ Kiijmdiitis 

 (irahs occurs, and resembles that species in its habits of crouching, but it allows one 

 to come within a few yards before rising. — A. B. P.]

[This fine bird is not uncommon in the sandy wadis. It is usually seen in 

 pairs and is very difficult to ap]iroach on foot, but on a camel one can usually get a 

 shot by riding round the bird in a circle as it crouches on the ground, for it then 

 allows one to approach within 30 or 40 yards before rising. The early morning, 

 when the birds are feeding, is the only time to look for them. The female from 

 Shaka had two three-parts-grown young with her, but we were only able to bag the 

 old one.— A. B. P.]

Houhara macqueeni (J. E. Gray); Yerbury, Ihis 1896, p. 33.

 Southern Arabia, but, so far, no example has been procured.

 Uj) to the present time the Courser found in Southern Arabia has not been 

 identified, but the species will probably jirove to be ('. (/aUieKs. The e.xamples shot 

 by Mr. Chevallier near Aden do not ajipear to have been identified.
