Loche in Algeria, which resembles those of the Black-throated Chat, but is slightly duller in 

 colour, and has larger pale liver-coloured spots collected round the larger end. Dr. E. Rey 

 informs me that he possesses two eggs collected in Algeria, which he compares to those of the 

 Russet Chat, but says that they are not so brightly coloured or so much spotted with rufous. 



Mr. Blanford, when at Frankfort in September last, examined Riippell's types in the 

 Senckenberg Museum, and convinced himself that the so-called male of Saxicola pallida, Rupp., 

 is the female of S. monacha, the specimens described as the female and young of that species 

 being females of Saxicola deserti. Riippell himself (Neue Wirbelthiere, p. 80) refers to his 

 figure of Saxicola pallida in the 'Atlas,' pi. 34. fig. a, as an immature bird, and states that the 

 adult bird was figured by Temminck (PI. Col. 472. fig. 1) under the name of Saxicola isabellina, 

 and says that it has the auricular region darker, and the terminal two thirds of the tail dark 

 brown — which clearly proves that he is speaking of the Desert-Chat; and I have also, from an 

 examination of the plate, found this to be the case, the specimen figured being a pale female of 

 S. deserti. Mr. Blanford and I have also examined the types of Saxicola gutturalis, S. albo- 

 marginata, ami »S'. homochroa, and convinced ourselves that they are all three referable to the 

 present species. 



The specimens figured are an adult male in breeding-plumage and a male in winter plumage 

 in the foreground, the adult female being in the background ; these are the specimens described, 

 and are in my collection.
