CONTRIBUTIONS TO TU H OllNIS OF SAUIIALIX. 29 



The Other lualo specimen still retains more of the Jnvenilu 

 l)lu Hinge, so that a great deal of the feathers of the breast arc 

 ochraceous with l)lackisli tips. The juvenile feathers whieh still 

 exist on the head and upper neck are dark blackish brown with 

 (piite narrow and light coloured shaft-stripes. 



Neither 0. sibirica nor daviso/ii is mentioned in Nikolski's 

 work so that it seems probable that this thrush is not common 

 in Saghalin, although it breeds there as attested by the present 

 collection.

In the year 1887 Stejneger^' established a new species of 

 thrush related to Tardus chrysolaus, and that he named T. 

 jouyi. The former should be characterized by having " axillaries 

 and greater under-wing-coverts pure gray ; " the latter by having 

 the same parts " gray, strongly suffused with rusty." In addition 

 to this difference, the bill of the former should be "larger" 

 and that of the latter " smaller." That author further expressed 

 the belief that the two "species" also differed "in the coloura- 

 tion of the throat. In adult male birds of T. chrysolaus the 

 feathers of this part are uniformly sooty black clear to the 

 grayish base, and more or less margined with rusty according
