Annals of the Transvaal Museum 
of 104 mm., and is a synonym of monticola] Sharpe {Birds of South Africa, 
p. 243, 1876) states that the type is from “Hykomkaap and Oosop on the 
Swakop River.” Sharpe, in the work just mentioned (p. 249), described 
yet another supposed species as Saxicola anderssoni, from Colesberg, 
Swakop River and Koysfontein (Great Namaqualand), the wing length 
being given as ii6mm.; Colesberg being the first locality cited may be 
taken as the type locality, the name thus being reduced to the synonymy 
of the eastern subspecies. Finally, Gurney [Ihis, 1877, p. 343) described 
5 . tephronota from Potchefstroom, giving a wing measurement of 116 mm. 
We arrive, therefore, at the conclusion that, apart from colour characters 
which are not yet understood, there are two subspecies with the following 
synonyms : 
Grillivora monticola monticola (Vieillot) : Namaqualand. 
Saxicola leucomelana Burchell: Griquatown. 
Vitiflora rupicola Boie: Namaqualand. 
Grillivora capensis Swainson: Namaqualand. 
Saxicola aequatorialis Hartlaub: “Gaboon"? 
S. castor Hartlaub: Karroo. 
Dromolaea alhipileata Bocage: Dombe, Benguella. 
Saxicola atmorei Tristram: “Damaraland" (Windhoek). 
S. diluta Blanf. and Dress. Swakop River. 
Grillivora monticola griseiceps (Blanford and Dresser) : Colesberg. 
Saxicola anderssoni Sharpe : Colesberg. 
S. tephronota Gurney: Potchefstroom. 
Amongst the other species of South African chats is a large grey one, 
which could easily be mistaken for the grey phase of the Mountain Chat, 
side by side with which it ranges on the west ; this similarity led Hartlaub 
to name them respectively Saxicola castor and S. pollux, the latter of which 
is distinguishable by the emargination of the second primary, on which 
account it is commonly referred to the genus Emarginata\ but it differs 
sufficiently from both Grillivora and Emarginata to be placed in a separate 
genus, for which I propose the name of Karrucincla gen. nov., type 
Saxicola pollux Hartlaub. Males have the second primary distinctly, but 
females less distinctly, emarginate, and it seems probable that there are 
several subspecies which remain to be named. In the Transvaal Museum 
collectiofi are the following specimens, with the dimensions recorded

Saxicola schlegeli Wahlberg I have not seen; but there is a good de- 
scription of the species in the Journ.f. Orn. 1857, p. 3, probably of a female, 
the dimensions being small and no mention being made of an emargination 
on the second primary. Reichenow includes the species in Emarginata, 
and Seebohm figures the wing of “ Myrmecocichla cinerea” {Cat. B. Brit. 
Mus. V. 358, 1881) clearly showing an emargination. I cannot agree with 
previous writers as to what Le Vaillant intended when he described the
