and vermiculated ; in the much narrower white borders of the 

 feathers of breast and sides, those of the flanks having white shaft- 

 stripes ; and in having the thighs and crissum darker and without 

 pure white edges. Adult males have the iris brown ; bill olivaceous 

 brown, orange at base below ; feet and claws black ; naked sides of 

 face and chin light red ; throat bright yellow. Females are similar, 

 but with less orange at base of bill below. 



Measurements of type-specimen (adult male).- — Wing, 204 mm.; 

 tail, 105; exposed culmen (chord), 33; tarsus, 67; longest spur, 22. 



Material. — Twenty specimens are referred to this subspecies. 



Remarks. — Thirteen specimens taken around the base of Mount 

 Kenia, at an altitude of 6000 to 7000 feet are typical kenicnsis. 

 Seven specimens from Fort Hall and Saba Saba, at altitudes of 3900 

 and 4000 feet, are intergrades between infuscatus and kenieiisis. 

 Specimens from Wambugu, Kapiti Plains, Ulukenia Hills, and the 

 Southern N'Guaso Nyiro River in the Sotik District are all typical 

 infuscatus. 



PTERNISTES LEUCOSCEPUS KILIMENSIS, new subspecies 



Mount Kilimanjaro Bare-throated Spur fowl 



Type-Specimen.-— Adult female. Cat. No. 117817, U. S. N. M. 

 Collected in the Mount Kilimanjaro Region, East Africa, i888-'89, 

 by Dr. W. L. Abbott. 



Characters. — This is the extreme of the dark forms of Pfernistes 

 leucoscepHS, and differs from Pteniistes leucoscepus infuscatus in 

 much the same way as does kenicnsis. Its closest affinity appears to 

 be with kenicnsis, from which it differs in having a general casta- 

 neous tone of coloration ; the light specklings of the wings and tail 

 and the shaft-streaks of the mantle and wing-coverts are chestnut 

 or rust color instead of grayish or buft'y white; the concealed pale 

 markings of the wing-quills are decidedly rusty instead of nearly 

 white ; the white edgings to the feathers of the breast and sides are 

 obsolete except upon the posterior flanks, and these parts have the 

 chestnut color extending to the subtriangular white spots at the tips 

 of the feathers. 



Measurements of type-specimen {adult female). — Wing, 181 mm. ; 

 tail, 82 ; exposed culmen (chord), 32 ; tarsus, 55. 



Material — Two specimens (one female and one unsexed) col- 

 lected by Dr. W. L. Abbott. 



Remarks. — The size is quite uniform in the three forms under 

 consideration.
