DUSKY IXOS. 205 



differs in the colours of the plumage, is very like the 

 one we have figured under the name of Ixos Vail- 

 lantii in the "PL Color.," or the Merle cul-jaune du 

 Cap of Buffon, "PL EnL," 317, which is the Brunoir 

 of Vaillant, "Ois. d'Afr.," pi. 106, f. 1. It resembles 

 also in all these characters many of the species of the 

 same genus scattered over the Isles of the Asiatic 

 Archipelago." 



The adult male and female have the top of the 

 head, cheeks, and throat, dull brown; nape, mantle, 

 back, and rump, a dull earthy brown; the whole of 

 the wing same colour, but rather more shining. Chest 

 and sides a clear brown; middle of the belly whitish 

 brown; abdomen and upper tail coverts dull white; 

 tail unicolorous blackish brown; beak and feet black. 



With this bird I complete the description of the 

 Thrushes and their allies. The two Water Ouzels 

 admitted by some authors, namely, Cinclus Pallasii 

 and C. melanog aster , would, according to the arrange- 

 ment of Temminck, follow next; but there is, I think, 

 no doubt that the last is a variety of C. aquaticus, a 

 well-known British bird, while the former is only an 

 inhabitant of Siberia, and that proof of its having been 

 found in the Crimea, as stated by Temminck, is 

 wanting. They are excluded by Schlegel and Dcgland, 

 and therefore I shall follow their example. 



I bring here my first volume to a close, a number 

 or so sooner than I intended, to avoid breaking in 

 upon the next group, the Sylciadce, which will occupy 

 the first six or seven numbers of Volume II. In 

 dealing with this family, I shall follow the arrangement
