20 Mr. C. H. B. Grant on a Collection of

 throated Francolin.

 British-German Border, S. of Kilimanjaro.

All are in good plumage, and both the females are rather 

 darker above than the adult male. 



The young is apparently in first plumage, having the tail 

 distinctly barred and dark mottlings on the inner secondaries 

 and coverts (these parts being finely speckled in the adult); 

 below, the markings are narrower, giving the young a much 

 darker appearance than tiie adult. It has no spurs.

 c? 212 mm. ; $ 197 & 193 mm. Jiw. Total length in flesh : 

 16 inches. Wing: 201 mm. 



\^Ad. Irides brown ; bill black, lower basal half orange ; 

 bare skin round eye and upper throat red, lower throat 

 yellow. 



Juv. Irides brown ; bill black ; bare skin round eye and 

 throat red, lower neck yellow ; legs and toes black. 



Several coveys of about fifteen birds eacli were seen along 

 the rivers ; they were very shy and escaped by running.] 



In naming these birds I have found it necessary to 

 examine the whole group, and have come to the following 

 conclusions : — 



Pternistes leucoscepus leucoscepus (Gray, List Gallmse 

 Brit. Mus. 1867, p. 48, descr. nulla) ; Heuglin, Orn. N.O.- 

 Africa, vol. iii. 1873, p. 899. 



It appears that Heuglin's is the first description of this 

 race, so that his name should stand as the author. 



Gray, however, gives the locality as Abyssinia, and as 

 Heuglin^s description is based on Gray's name this locality 

 can stand. 



There are specimens in the British Museum from theLebka 

 Valley, Koomayli, Rairo, Sahati and Zoulla ; all in Eritrea.
