than from T. ferreti, or than even does the latter from T. viridts. 

 However, from T. viridls in rufous-backed stage, T. perspicillata may 

 readily be distinguished by its brown instead of black wing-quills; 

 uniform rufous wing without white edgings or black coverts- exten- 

 sively white lining of wing; whitish abdomen; white under tail-coverts; 

 paler breast; and more greenish metallic shade of head and throat' 

 which color is less extended posteriorly on the lower surface. 



The geographical distribution of these three species is al)out us fol- 

 lows: 



Tchitrea perspicillata (Swainson).— Southeastern Africa, north to 

 near the Zambesi River. 



Tchitrea ferret iXjuiv'm {= TcJiltrea 'per^picillaia suahelica [Reich- 

 enow] ). — Eastern and northeastern Africa, from the Zambesi River 

 to Abyssinia and Somali Land. 



Tchitrea viridis (Miiller) {^Tchitrea cristata [Gmelin]). — West- 

 ern Africa, from Senegambia to Gabun. 



Family LANIID^E. 



POMATORHYNCHUS SENEGALUS ARMENUS, new subspecies. 



Chars, subsp. — Similar to Pomatorhynchus senegalus seriegahis in size 

 and general color, but upper parts more rufescent, the anterior i)ortion 

 of the superciliar}^ stripe tinged with ochraceous instead of being pure 

 white; lower surface more washed with butfy. 



Desa'iption. — Type, adult male, No. 118,148 U.S.N.M.; Plains of 

 Taveta, British East Africa, June 28, 1888; Dr. W. L. Abbott. 

 Pileum, lores, and postocular streak black; superciliary stripe ochra- 

 ceous butf, paler anteriorly; upper and lower eyelids white; cheeks 

 buffy whitish; ailriculars and sides of neck tawny clay color; cervix, 

 back, and scapulars reddish chestnut, the last with broad brownish 

 black centers; rump and upper tail-coverts hair brown; middle tail- 

 feathers broccoli brown, numerously and narrowly barred with darker 

 brown; remaining rectrices black, with broad white tips which increase 

 in size on the outer feathers, the two outermost also narrowly margined 

 with whitish on the distal portion of their outer webs; wing-quills 

 fuscous, broadly edged externally with ferruginous, the teitials also 

 bordered on both webs with a lighter shade of the same; superioi- 

 wing-coverts ferruginous, the greater series with narrow shaft mark- 

 ings of blackish; ventral surface white, washed with buffy, particularly 

 on the lower tail-coverts; the breast, sides, and flanks more or less 

 shaded with grayish; edge of wing white; lining of whig and inner 

 edges of wing-quills basally tawny. 



Two of the specimens on which the description of this form is based 

 were recently recorded as Pomatorhynchus senegalus senegalus.," but
