108 Mr. H. E. Dresser's Notes on 



He further says (p. 114) that the first specimen he saw 

 was obtained by TerentjefF late in September 1864^ and he 

 (Severtzoff) was struck at once by its small size. In colour, 

 he writes, " it is more brown, the upper parts being almost 

 pure brown ; the nape is marked with blackish lines, the back 

 and shoulders barred with greyish ; tail light brown, with 

 eight greyish cross bands, the underparts yellowish white, 



marked with very narrow reddish grey spots.'' " The 



male killed at Chimkent in the winter of 1866 is greyer, the 

 spots on the breast are broader, and in general colour it 

 resembles the young of F. aesalon, but is much smaller, 

 measuring, total length 12" 3'", extent 24" 7"', whereas F. 

 cesalon measures 13 inches in length and 24" 6"' in extent. 

 From these descriptions it may be judged whether F. alau- 

 darius is a good species or not ; but it would be necessary to 

 have a larger series in all stages of plumage to determine this. 

 Most probably a small male of so-called F. (Esalon was shot on 

 the Irtysh on the 16th of April, 1864. It measured, total 

 length 12" 1'", extent 25", wing 8" 5"', tail 5", tarsus 13"', 

 middle toe 14'", culmen 7"'. It differs in having the nape 

 lighter-coloured, the feathers being tipped with white ; the 

 feathers on the head, back, and Avings are tipped with yel- 

 lowish, and the tail is strongly barred with blackish."
