with elegans to some extent, but the birds of Barsaloi are of the 

 latter race. 



5. S. d. elegans. — Southern Somaliland, Jubaland, and extreme 

 northern Kenya Colony southwest to Barsaloi (three specimens 

 Am. Mus. Nat. Hist.). 



6. S. d. griseiventris. — Northern Somaliland, southern Eritrea, and 

 the Hawash region of Ethiopia to the Arussi country. This race is 

 not too well differentiated from the typical form and individuals 

 occur that may be placed with either form equally well. 



The other named form, amMgua^ does not occur in eastern Africa, 

 but is restricted to Angola, the Katanga, and western portions of 

 Northern Khodesia. The so-called kafuensis which is generally 

 considered the same as amMgua (and which I have not seen) is said 

 to be darker than the latter. This suggests that the birds on which 

 this Rhodesian form was based are merely intermediates between 

 ambigua and 'permista.^ a suggestion which conforms very well with 

 geography in this case. 



STREPTOPELIA DECIPIENS PERMISTA (Reichenow) 



Turtur amhiguus permistus Reichenow, Vog. Afr., vol. 3, 1905, p. 808: 

 Maliwungu, Tanganyika Territory. 



Speci7nens collected: 



Three females, Gato River, near Gardula, Ethiopia, March 31 to 

 April 14, 1912. 



These three specimens are somewhat intermediate between per- 

 mista and griseiventris, but are nearer the former. They are notice- 

 ably darker below and above than two specimens from northern 

 and northwestern Tanganyika Territory (Mwanza and Bukoba). 



The wing measurements given by Zedlitz ^° are larger than those 

 of the present series. His figures are 160-165 millimeters, while my 

 measurements are 156.5-158 for the Ethiopian examples and 159.5 

 for those from Tanganyika Territory. However, all mine are based 

 on females, and his were probably based, at least partly, on males, 

 although no indication of sex is given. However, the measurements 

 given by Granvik ^^ agree with mine, and it is noteworthy that his 

 birds are males; wings, 155-157 millimeters. 



The exact geographical location of the type locality Maliwungu, 

 is a matter that should be made clear. I have not found it on any 

 map, and Reichenow, in the atlas of his great work, merely suggests 

 '" Rovuma River(?)," which is, of course, the border line between 

 Tanganyika Territory and Mozambique.
