from Ovaquenyama and Ochimbora in Ovampoland, where they were 

 obtained by Eriksson. These can be at once distinguished by the 

 general rufous tinge on the back as well as the crown. 



298A. TURDUS LIBONIANUS TROPICALIS (Ptl'S.). 



298B. TURDUS LIBONIANUS VERREAUXI (Boc.). 



Hellmayr (Journ. Ornith., 1902, p. 219) distinguishes these two 

 subspecies of the Kurrichaine Thrush from Inhambane and the 

 Lower Zambesi to Tanga in East Africa, and from Ombongo and 

 Angola respectively. The former has darker brown upper parts and 

 a more orange shade over the breast than the type ; the latter is 

 greyer above and has the greater part of the breast brownish grey, 

 while the white portion of the lower surface is more widely spread 

 and the orange portion more restricted. 



307. SAXICOLA MONTICOLA (Vieill.). 



A further discussion of the Mountain Chat, with its very puzzling 

 series of plumage changes, is given by Hartlaub (Notes Leyd. Mus 

 xxii. p. 153) and Sharpe (Ibis, 1904, p. 327), but no definite con- 

 clusion is reached by either author, except that the latter is inclined 

 to consider the Damaraland race as a distinct species under the 

 name Saxicola leucomelcena, because of its creamy-white or pure 

 white crown. 



312. SAXICOLA LAYARDI Sharpe. 



As has been pointed out by Sharpe (Ibis, 1904, p. 325), the web 

 of the second primary of this Chat is slightly ernarginated at the tip, 

 so that the species should occupy a position somewhat intermediate 

 between the genera Saxicola and Emarginata. 



313. SAXICOLA FAMILIARIS Stephens. 



313A. SAXICOLA FAMILIARIS GALTONI (Strickl.). 



313B. SAXICOLA FAMILIARIS HELLMAYRI Beichw. 



Beichenow (Om. Moiiatsb. x. pp. 77, 78, 1902) recognises two 

 geographical races of the Familiar Chat from Damaraland and the 

 Transvaal respectively. The former, which he names S. luebberti, 

 but which, if distinct, should be called S. galtoni, is a paler form 

 of the typical race, and has a very broad black band at the end of 

 the tail ; the latter, S. familiaris hellmayri, has the black band on 

 the tail very much narrowed and broken up, and even absent alto- 

 gether on some of the feathers ; the general colour of the tail, too, 



is a lighter chestnut.
