the " Elephant^s River/' i. e., Olipliant River, western 

 Cape Colony, and therefore this name must refer to the 

 western and paler race. Sylviella Jlecki Reicliw. O. M. 

 1900, p. 2.2, from south of Lake Ngami, is therefore a 

 sytionym. This race is characterized by its strong beak, 

 plainly marked dark streak throngli the eye, and whitish 

 superciliary stripe ; the underside is pale rufous. Wing 

 58-62 mm. It extends from western Cape Colony through 

 S.W. Africa, Namaqualand and Bechuaualand, probably to 

 the western Transvaal. 



For the other and richer coloured race we propose the 

 name — 



2. SyLVIKTTA RUFESCENS TRANSVAALENSIS, SUbsp. UOV. 



A race very similar to S. r. rujescens but more richly 

 coloured, with a more rufous uriderside. Slightly larger, 

 wing 60-65 mm. Type, a specimen collected at Rusten- 

 berg, 6 June 18/8, by W. Lucas ; no sex given. B.M. reg. 

 no. 95/5/1/1053. 



Range. Transvaal, except the western portion, and South 

 Rhodesia. There are also in the Museum collections four 

 specimens from N. Rhodesia and Nyasaland which appear 

 to be indisLinguishable in size and coloration from this race. 

 Further material, however, may prove this to be distinct. 

 It apparently occurs side by side with S. ivhytiijacksoni. 



'6. SyLVIETIA RUFESCENS PALLIDA. 



kiylvitllu pallida Alexander, Bull. B. O. C. viii. 1<S98, 

 p. 48 : Zambesi River, 30 miles above Tete. 



A much paler race, apparently confined to the Zambesi 

 valley. Similar to S. r. ri/fescens but paler, especially on 

 the throat, and with a smaller bill. Smaller ; wing 

 55-58 mm. 



Range. Confined to the Zambesi valley in the neighbour- 

 hood of Tete. 



It is curious to find a pale race in a locality like this, 

 especially as a darker race is found to north and south 

 of It.
