NORTHERN ZOOLOGY. 



we are more disposed to view this bird and Se'iurus aurocapillus as entering in 

 the circle of Accentor, than to place them within the confines of the Motacillince. 

 If this eventually proves to be their real station in nature, Se'iurus becomes, of 

 course, a sub-genus. Do they, in fact, possess the same analogical relations ? 

 We suspect not. — Sw. 



This bird was seen only at Carlton House, where it frequented the moist and 

 thickly-wooded points of the river. It arrived in May, and disappeared after a 

 few days, probably going farther north to breed. 



DESCRIPTION 



Of a specimen, killed at Carlton House, lat. 53°, May, 1827. 



Colour. — Whole upper plumage a remarkably uniform and very deep hair-brown. Eye- 

 stripe, chin, and whole under surface very pale primrose-yellow ; throat, breast, and flanks 

 marked at the tips with wedge-shaped spots of the colour of the upper plumage. Inner 

 wing coverts yellowish-grey, spotted with brown near the edges of the wing. Bill dark 

 umber-brown above, paler beneath. Legs brownish. 



Form, &c. — Bill rather wider than high at the base ; upper mandible somewhat suddenly 

 narrowed in the middle ; tip slender and minutely notched. Three first quills equal, the 

 rest diminish in succession, the greatest interval occurring between the fourth and fifth. Tail 

 square, or very slightly rounded ; its feathers obliquely truncated on their inner webs, which 

 are broader than those of S. aurocapillus. Tarsus slender and considerably longer than 

 the middle toe : first phalanx of the outer toe adherent to the middle one : lateral toes nearly 

 equal. Nails very small : they are more curved, and the hind one is longer than in S. auro- 

 capillus ; but the structure of the feet is otherwise alike in both.
