206 Mr. H. B. Tristram on some 



ashy head, others wholly black, some with the belly ashen, some 

 black, and some with more or less white. 



Among the species before me there are four which, so far as I 

 am aware, are new and midescribed. The Jfirst of these (of 

 which a figure is given) I propose to name after its discoverer, 

 Mr. Arnott, and subjoin its description. 



Saxicola arnotti, sp. nov. (Plate VI.) 



^ Corpus totum superne et subtus nigerrimum ; pileo plumis 

 quibusdam albis interraixtis; fronte et linea superciliari

 remige primo X"5 poll., secundo 3 poll., octavum sequante, 

 tertio ad septimum eequalibus : rostro, tarsis et pedibus

Long. tot. 7'2, rostr. a rictu '8, al. 3"9, caud. 3, tars. Tl.

This bird appears to be the South-African representative 

 of the Abyssinian Saxicola lugubris, Riipp., and differs from it 

 in its much greater size, in having the narrow white instead of 

 the broader chestnut rump of that bird, and in the much less 

 extent of the black bar at the extremity of the tail. I name this 

 species after Mr. W. Atmore, a diligent observer of birds, as Mr. 

 Layard's pages testify. 



Saxicola modesta sp. nov.* 



Caput et corpus totum superne pallide cinereum, subtus totum 



* It is possible that this species may be identical with the Erithacvs 

 schlegeli of Wahlberg (K. Sv. Vet. Alcad. Forhandl. 1855, p. 213), though 

 the bird is certainly not an Erithacus, but one of the Saxicolce closely ap- 

 proaching Pratinculu.
