6. PoLiospizA BURTONI TANGANJiCiE Grranvik (ex Reiche- 

 now MS.) (Journ. fur Ornith. 1923, p. 191 : Lake 

 Tanganyika). 



Allied to the Elgon race, but easily distinguisbed from it, as 

 well as from the Kilimanjaro bird, by its much smaller and 

 weaker bill. Size smaller than the Elgon form. Upper 

 parts darker than in P. h. somereni, but not as dark as in 

 P. h. kilimensis. Wings, ^ 80-86 mm., ¥ 80-83 mm. 



Hah. Ruwenzori, Birunga Volcanoes and mountains west 

 of Tanganyika. 



Count Nils Gyldenstolpe also describes a new subspecies 

 of Triclioplwrus as follows : — 



Trichophorus swainsoni bannnermani, subsp. nov. 



Diagnosis. Most closely related to Neumann's Criniger 

 swainsoni (Orn. Monatsber. 1914, p. 8), and then distin- 

 guished from the races of T. c. calurus Cassin by having a 

 shorter and considerably weaker bill. Differs from both 

 T. swainsoni and T. c. ndussumensis Reichenow by having 

 the upper tail-coverts and rectrices rufous instead of olive- 

 green. From the former it further differs by having the 

 upper parts of the body of a more saturated olive-green. 

 Centre of breast and belly bright yellow. Sides of breast 

 and underparts nearest to dark citrine (Ridgway). Under 

 tail-coverts ochraceous olive. Rectrices and upper tail- 

 coverts slightly more rufous than in typical T. c. calurus 

 Cassin from Cameroon. 



Height of bill at nostrils slightly less than one-fourth the 

 length of the culmen. 



Dimensions of tyi^e : — Total length 195 mm.; wing 91 mm.; 

 tail 82 mm. ; culmen 17 mm. ; bill from gape 22 mm. ; width 

 of bill at nostrils 5 mm. ; height of bill at nostrils 4-5 mm. ; 

 tarsus 20 mm.
