h.' A naked space around eye; bristles of bill well developed. 

 c. First toe about ecjual to half of fourth; secondaries falling

VIRIDIBUCCO LEUCOMYSTAX (Sharpe). 



Barhatiila /euroini/!^t<t.r Hharve, Ibis, 1892, p. ;!10 (Sotik, British East Africa). 

 Two specimens: an adult male, from Mount Kilimanjaro, at 5,000 

 feet, September 1, 1889; and an adult female, from Mount Kilimanjaro, 

 at 6,000 feet, November 10, 1888. The male is a little brighter in 

 color above than the female, but in other respects appears to be 

 identical. 



Family INDICATORID.^. 



INDICATOR INDICATOR (Sparrman). 



Cuculux indicator Sparrman, Philos. Trans., 1777, p. 43 ("Groot Vaders Bosch," 



near Swellendam, vicinity of Cape of Good Hoj^e, South Africa). 

 Cucuhis indicator Gmelin, Syst. Nat., I, 1, 1788, p. 418 (interior of Africa). 



Two specimens: an adult male, from the plains east of Mount Kili- 

 manjaro, October ,5, 1888; and an immature male, from the Useri River, 

 Mount Kilimanjaro, December 13, 1888. The latter is in the plumage 

 which so closely and puzzlingly resembles Indlvator iiKUor, the short 

 median upper tail-coverts being pure white, the jugulum and throat 

 tinged with yellow, the chin faintly washed with the same, the Hanks 

 without brown streaks, the f(>athers of the forehead and crown mar- 

 gined with yellowish brown; ])ut the chin and upper throat are mot- 

 tled with Ijrownish l)lack and the bill is pale brownish, l)oth of which 

 are distinguishing marks. 



MELIGNOTHES MINOR DIADEMATUS (Riippell). 



Indlcatirr diadeiiidtus Ruppell, Neue Wirb. Faun. Abyss., Vogel, 1885, p. HI 



(wooded region of Abyssinia). 

 Indicator ntinor te.iiensis Neumann, Journ. f. Ornith., 1900, p. 195 ( Hura, Teita, 



British East Africa). 



A single female was obtained by Doctor Abbott at Taveta, July T. 

 1888. ''Skin extremely tough.'' Its measurements are: Wing, 8'2; 

 tail, .51; exposed culmen, 9.5; tarsus, 14; middle toe, 12 nmi. 



That two species of small honey-guides inhabit most of Abyssinia 

 was suspected by Ruppell, who distinguished them and named the 

 paler one diadentatua;^^ by mistake, however, considering the darker
