BIRDS OF ETHIOPIA AND KENYA COLONY 223 



The immature plumage, which appears to be undescribed, is as 

 follows: Head and underparts dull sandy ochraceous gray, palest 

 on the throat and abdomen which are very light, the forehead some- 

 what paler than the rest of the top of the head; all the feathers 

 terminally edged with buffy white, giving ja faint barred effect to 

 the bird; upper parts deep olivaceous ashy brown, each feather 

 tipped narrowly with pale buff, the tips on the remiges somewhat 

 broader and wider. 



A complete postjuvenal molt brings on the adult plumage. The 

 molt begins on the throat, chin, and abdomen, then spreads to the 

 under tail coverts, the middle and greater upper wing coverts then 

 to the innermost primaries and outermost secondaries; then to the 

 crown, nape, lower back, rump, and outer tail feathers. The rectrices 

 molt centripitally. The last parts to change are the breast and 

 interscapulars. The immature male from Gato River is in an 

 advanced stage of the postjuvenal molt. 



STREPTOPELIA DECIPIENS GRISEIVENTRIS (Erianger) 



Turtur decipiens griseiventris Erlangeb, Journ. f. Ornith., vol. 53, p. 126, 

 pi. 6, fig. 26, 1905 : Artu, north Somaliland. 



Specimens collected: 



Male, Dire Daoua, Ethiopia, December 5, 1911. 



Female, Sadi Malka, Ethiopia, January 28, 1912. 



These specimens are confusing in that neither is typical griseiven- 

 tris. The male from Dire Daoua is intermediate between this form 

 and elegans and is very light on the belly and under tail coverts, 

 while the female from Sadi Malka is nearest to g7^iseiventris but ap- 

 proaches decipiens. Neither agrees with Erlanger's description and 

 figure of griseiventHs as well as others from places more remote from 

 the type locality, such as Maraco, Lake Zwai, and the Arussi country. 

 This form seems to be the least well founded, its characters the 

 least stable and constant, of any of the seven subspecies. (In the 

 course of this study six specimens of griseiventris have been 

 examined.) It is supposed to be more violaceous on the nape and 

 underparts than decipiens. 



The color of the nape and occiput varies as in perspicillata. The 

 bird from Sadi Malka has these parts much suffused with vinaceous 

 pink, while in that from Dire Daoua, the pinkish is confined to the 

 nape. The wing measurements of the series of this race vary from 

 166-170 (male) and 160-172.5 millimeters (female).
