NO. 1411. BIRDS FROM MOUNT KILIMANJARO— OBERHOLSER. 841 



PTEROCLES GUTTURALIS SATURATIOR Hartert. 



Pterocles gutturalis saturatior Haktekt, Novit. Zool., 1900, i>. 29 (Ciinipi-ya-Sinilja 

 British East Africa). 



Two adult males: one from the plains cast of Mount Kilimanjaro, 

 September 23, 1888; the other from the plains of Kilimanjaro, August 

 21, 1888. The black bars on some of the lower tail-coverts, which are 

 present in both these specimens, seem to be nothing- more than an 

 individual variation. 



Family TRERONID^E. 



VINAGO CALVA WAKEFIELDI (Sharpe). 



Tveron wakefieldi Sharpe, Proc-. Zool. Soc. Loud., 1873, j). 715, pi. lviii, tig. 2 

 (Mombasa, British East Africa). 



Two specimens, adult male and female, from Mount Kilihianjaro, at 

 5,000 feet, September 1, 1889. "Iris (of both) white; bill whitish; 

 cere light orange; feet dark red.'' The female is smaller than the 

 male, also darker and duller colored, with a much less pronounced 

 plumbeous hind-neck, and a grayish green instead of greenish slate- 

 gray tail. These two birds are not typical of wakefieldi^ being larger 

 and having tails that incline to slate grayish; but they are apparently 

 much nearer this form than to Vtuago calva nudirostris; they further- 

 more present in their intermediate characters almost indisputable 

 evidence that wakefieldi is but a subspecies of V. calva^ and therefore 

 its easternmost representative. There are thus four forms of Vinago 

 calva, as follows: 



Vinago calva calva (Temininck and Kiiip). — West Africa, from Sierra Leone to 



Angola. 

 Vinago calva nudirostris (Swainson). — Central Africa and the interior of East 



Africa, north of the Zambesi River; northwest to Senegal. 

 Vinago calva wakefieldi (Sharpe). — Coast region of East Africa, from southern 



British East Africa to the Zambesi River. 

 Vinago calva schalowi (Reichenow). — South Africa, from Matabele Land to 



Ovambo Land. 



Family COLUMBID.E. 



COLUMBA ARQUATRIX ARQUATRICULA (Bonaparte). 

 Columha arqiudricula Bonaparte, C'onsp. Avium, II, 1854, j). 50 (Abyssinia). 



Two specimens, adult male and female, from Moimt Kilimanjaro, 

 at 6,000 and 5,000 feet, respectively. The male, taken November 10, 

 1888, is in nearly completed molt. "Iris white; bill and feet bright 

 yellow." 



These differ so much from trite Columha arquatrix of southern 

 Africa'^' that they represent without apparent doubt a well character-
