on the primaries, the latter having dark brown ends, excepting the inner

 whitish ash. Tail : centre-feathers with the basal half rufous buff and the 

 terminal half pale brown, broadly edged and tipped with sandy white ; 

 remainder of the tail white and dark brown, the latter forming a triangular 

 pattern with the apex about half way down the centre-feathers; all the 

 feathers with white ends, broadest on the inner webs. A narrow frontal

Gray's Desert-Lark inhabits Damaraland. 



The type was discovered by Wahlberg on the sandy desert 

 between the Swakop and Kaisip rivers near Walfisch bay. 

 Chapman also met with this species " on the barren plains in 

 the neighbourhood of Walfisch bay, as well as for a short dis- 

 tance inland, but not so far inland at Otjimbinque. A few 

 individuals were generally found in company." According to 

 Andersson, " it feeds on seeds and insects and is comparatively 

 tame, but where grass abounds it is difficult to secure." 

 There are seven of Andersson's specimens in the British 

 Museum, all from Damaraland, so the range of the species 

 appears to be extremely limited, and I am not aware of any 

 others having been procured since Andersson's time. 



The egg is described by Mr. A. Nehrkorn as white, 

 with small violet and greyish yellow spots, and measuring 

 0-88 X 0-6. 



Genus VI. BOTHA. 



Bill apparently pink in life, conical, with the culmen very nearly straight ; 

 nostrils hidden. Wing of ten primaries ; bastard primary long, similar to 

 that of Galerita ; tarsi and feet also as in Galerita, and the hind claw 

 slightly curved and longer than the hind toe. Tail half white and half 

 blackish brown, the dark portion forming a triangle with the base at the 

 end of the tail and the apex at the base of the two centre-feathers.
