culmen 8.7-9, tarsus 13.5-14; female: wing 66-72, tail 45, culmen 9, 

 tarsus 12. 



A Juvenal female resembles the adult but bas the feathers of the 

 breast and abdomen transversely obscurely barred with paler and 

 with duskier olive; the rectrices more pointed, with less dusky terminal 

 blotches. 



I. exilis pachyrhynchus: Similar to /. e. exilis, but larger, slightly 

 darker grajnsh, less olivaceous, below; occasional specimens have the 

 throat indistinctly streaked with dusky. Measurements in milli- 

 meters: male: wing 74.5-82, tail 48-54.1 (one 59.8 from Dundazi, 

 southwestern Lake Kivu), culmen from base 8.5-10, tarsus 13-13.5; 

 female: wing 73.2-74.5, tail 44.5-46.5, culmen from base 8.5-9.5, 

 tarsus 12. 



I. exilis meliphilus: Similar to I. e. exilis, but much paler below, 

 much less distinctly streaked, more uniform, above, the top of the 

 head more strongly tinged with olive green. In the original descrip- 

 tion this race is said to be larger than the nominate race, but further 

 material of both forms shows that this is not a constant character. 

 Measurements in millimeters: male: wing 73-79, tail 44-48, cul- 

 men from base 8-9, tarsus 12.5-13.5; female: wing 70-76.2, tail 

 41.2-48.2; cuhnen from base 7-8.4, tarsus 12.2-12.5. The type 

 specimen, collected by W. L. Abbott, no longer fits the description as 

 the whole anterior part of the head back to the occiput, auriculars, 

 and throat have darkened due to the collector's use of a solution of 

 corrosive sublimate as a preservative on the bill, thereby completely 

 hiding the white loreal spots and reducing the color characters of other 

 parts. For this reason, the description given by Oberholser (Proc. 

 U. S. Nat. Mus., vol. 28, p. 869, 1905), with which fresh material 

 agrees, is a more reliable reference basis than the type itself. 



It appears that the supposed race angolensis is best treated as the 

 same as meliphilus, but further material may demonstrate that the 

 Angola population is slightly larger, especially in wing length, slightly 

 duskier on the back, and with more pronounced dark shaft stripes on 

 the feathers of the flanks than typical East African meliphilus. 



The colors of the soft parts of an adult female from the southern 

 Guaso Nyii'o, Kenya Colony, are recorded as foUows: iris dark brown, 

 biU lead gray, base of the lower mandible flesh pink, bare skin around 

 eye lead gray, feet dull blue-gray. 



Native Names 



The Bulu people of the Cameroons caU this bird "male"; the 

 Lulega tribe, Lake Kivu, eastern Belgian Congo, call it "semanzuki," 

 while in the Upemba Park, also Belgian Congo, it is called "mpia."
