Sir Frederick Jackson forwarded the description of 

 two new birds from Kenya Colony, which he proposed 

 to name 



Tricholsema lacrymosnm narokensis, subsp, no v. 



Most nearly allied to T. lacrymosmn lacrt/mosum, but 

 distinguished from that species by the m^Ich larger pear- 

 shaped drops on the sides of the body, and the belly more 

 strongly washed with sulphur-yellow. In size the new race 

 is larger : wings measuring 72-74, as against 65-71 mm. 

 in the typical form. Six skins were examined. 



The Uganda race, T. I. radclifei, is distinguished at a 

 glance by the round instead of pear-shaped spots. 



T. l. narokensis is restricted to Doinyo Narok, 4300— 

 4500 feet, Kenya Colony. 



The type has been presented to the British Museum. 

 Doinyo Narok, 4500 feet, 9.iii. 06. F. J. Jackson coll. 



Colius striatus marsahit, subsp. nov. 



From C. s. vgandensis this race may be easily distin- 

 guished by the deeper chestnut of the underparts and by 

 the greyer (less brown) colouring of the upper parts. 



The bird is confined, apparently, to a limited area, the 

 nine skins in my collection having all come from Marsabit 

 (4000 ft.), an isolated extinct volcano in Kenya Colony. 



The type has been presented to the British Museum. 

 ^ ad. Marsabit, 4000 feet, l.ix. 09. F. J. Jackson coll. 



In company with Mr. Bannerman 1 have carefully con- 

 sidered the validity of C. s. Ukuyuensis van Someren, and 

 we both agree with the conclusions expressed by Dr. H. 

 Granvik (J. f. O. 1923, p. 95). We cannot see the slightest 

 difference between C. s. ugandensis and C. s. klkuyuensis. 

 Dr. van Someren^s C. macrourus griseogularis is, on the 

 other hand, a well-established form, the differences being 

 clearly visible in the specimens in my collection.
