Vol. 74 66 1954 therefore the nominate one, and the richer subspecies of the south and east, being without a name, is described below as S. r. diverga, Sketch map showing the approximate ranges of the South African races of the Crombec Sylvietta rufescens (Vieillot). 1. rufescens; 2. ochrocara; 3. diverga; 4. resurga; 5. flecki; 6. pallida. Material from Great Namaqualand is scarce in South African museums and it is not possible on the few skins available to arrive at any con- clusions, but a single specimen from Great Brukaros Mountain is paler than a skin of S. r. rufescens from Kalkfontein in the south of the territory. That this is a progressive trend is clear from an examination of material from still further north in Damaraland. Specimens from Damaraland differ from S. r. rufescens as here defined in being paler and clearer grey on the upper-parts, but ventrally there is no prominent difference. Ober- holser, "Smithsonian Miscellaneous Collections," xlvii, 1905, p,373, has proposed the name S. r. ochrocara for the Damaraland populations, but the separation has to the best of my knowledge never been given support by workers. I am of the opinion that subspecific status should now be accorded the populations of Damaraland, and that the name conferred on them by Oberholser should be resurrected for this purpose. The Kaokoveld and Mossamedes populations may belong here, but I have seen no material. In Ovamboland, and to the east of the range of S. r. ochrocara, the populations show marked differences, the birds being more bluish grey above and rather richer cinnamon-buff below, and the bill is invariably shorter (usually about 15mm.) and straighter.
