middle of the upper chest, deep gull gray sides and flanks, with a 

 broad buff y- white collar separating the dark colors of the sides and 

 chest from the black of the throat, and a darker general coloration. 

 From M.afer thruppi (Shelley), from northern and central Somali- 

 land, it may be readily distinguished by the absence of a decided 

 tinge of buff to the cheeks, ear coverts, and under parts. 



Description of adult male and female. — Head glossy black, with 

 a white patch below the eye beginning as a narrow line from the 

 angle of the mouth to below the eye, expanding to occupy the upper 

 cheek and all of the ear-coverts, this rounded white spot surrounded 

 by the black of the neck ; mantle, rump, and least wing-coverts smoky 

 slate-gray ; a nuchal spot of dirty white, ten millimeters in diameter, 

 between the black crown and gray mantle ; upper tail-coverts black ; 

 wings black, or brownish black, the median and greater coverts and 

 all of the quills edged with grayish white ; edge of wing white with a 

 black spot at base of feathers; rectrices black, the outer ones edged 

 and tipped with white ; the black of the lower throat, which is pointed 

 below, separated from the deep gull gray of the sides by a continuous 

 collar of dirty white, obscurely continued around the sides of the 

 neck to unite with the whitish nuchal patch ; a black spot occupies the 

 middle of the upper chest below the whitish collar ; center of abdomen 

 washed with rusty white ; thighs and crissum soiled grayish white ; 

 axillars, under wing-coverts, and inner edge of quills soiled grayish 

 white. In dry specimens the bill, feet, and claws are blackish.

ZOSTEROPS SENEGALENSIS FRICKI, new subspecies 

 Frick's White-eye 



Type-specimen. — Adult male, Cat. No. 245874, U. S. Nat. Mus. ; 

 collected on Bowlder Hill, Thika River, British East Africa, August 

 28, 1912, by Edgar A. Mearns. (Original number, 23936.) 



Characters. — Most closely related to Zosterops senegalensis stuhl- 

 manni (Reichenow), from which it differs in being considerably 

 smaller, with less yellow on the forehead. The back is greener and 

 the under parts yellower than in Z. s. smithi of southern Abyssinia ; 

 and it may be easily separated from Z. s. Havilateralis, from the coast 

 region at Mombasa, by its more yellow coloration throughout.
