THE HONEY-GUIDES 229 



Adult female: Similar to the male, but with the white loreal spots 

 and the dusky malar stripe less conspicuous; size somewhat smaller. 

 Measurements in millimeters: wing 65-79; tail 39-49; culmen from 

 the base 8-9.5; tarsus 11-13 mm. 



Juvenal: Similar to the adult but less distinctly streaked on the 

 back, more streaked on the crown and occiput; the lores not white but 

 olive like the cheeks, the entire upperparts, head and body, more 

 tinged with greenish, the malar stripes absent or very indistinct (per- 

 haps due partly to the fact that the sides and underparts of the head 

 are generally darker than in the adult) ; throat, breast, and abdomen 

 duskier and with a more pronounced olive smudge, and the rectrices 

 narrower and noticeably more pointed. A young bird from the 

 Cameroons is said by Sharpe (1907, p. 440) to have the bill reddish 

 brown, the feet pale reddish brown. 



Natal down: Unknown, if any. 



The plumage characters of the seven subspecies differ from the 

 above as outlined below. 



/. exilis ansorgei: Differs from typical exilis in having the head paler 

 gray, lacking the olive wash; in having the feathers of the back and the 

 wings less distinctly streaked, their median portions less different 

 from their margins; and in being somewhat larger generally. Meas- 

 urements in millimeters: male: wing 80, tail 47, culmen 8, tarsus 12.5; 

 female: wing 71, tail 42, culmen 8, tarsus 12.5. 



/. exilis leona: Agrees with /. e. ansorgei in having the upperparts 

 less streaked than in I. e. exilis but is even more uniform oilve on the 

 interscapulars and upper back; on the underparts it is slightly darker, 

 deeper olive brown than I. e. exilis; size small. Measurements in 

 millimeters, one male; wing 70, tail 42, culmen 9, tarsus 11. 



/. exilis willcocksi: Like /. e. exilis but has the whole of the crown 

 and neck greenish, the upperparts more brownish olive, not grayish. 

 Soft parts: iris dark bro^vn, bill black, feet very dark gray. Measure- 

 ments in millimeters: male: wing 77, tail 51, culmen 8, tarsus 12; 

 female: wing 68, tail 39, cuhnen 8, tarsus 13. 



/. exilis hutsoni: One of the largest of all the subspecies; the upper- 

 parts of the body less conspicuously streaked than in the nominate 

 form, and the underparts paler, almost as in /. e. ansorgei from which 

 form it is recognizable by the fact that the entire head is olive like the 

 back in hutsoni, not grayer than the back as in ansorgei; the bill 

 broader and more swollen than in any of the other races. Measure- 

 ments in millimeters: males: wing 78.2-80.0, tail 50-50, culmen 

 8.5-9, tarsus 14-14. 



/. exilis poensis: Differs from /. e. exilis in having the entire head 

 gray, and the general tone of the upperparts of the body slightly paler 

 in tone. Measurements in millimeters: male: wing 74-79, tail 48-50,
