THE present species was described by Latham from examples in the collection of Sir Joseph Banks, 
obtained during Cook's third voyage, and the locality is given as George's Sound. Іп 1785 Pennant 
described his ** Varied Thrush " from specimens procured in Nootka Sound : these were probably the 
identical ones which had served for Latham's description. In 1831 a bird obtained by Sir John 
Richardson at Fort Franklin was named by Swainson Orpheus meruloides, under the mistaken 
impression that it was allied to the Mocking-birds. 
Very early in the present century Pallas received a female example of the species from the island 
of Kodiak, off the coast of Alaska. It was sent to him by his friend Captain Billings, and it was 
described by Pallas under the name of Turdus auroreus. This name has erroneously been applied to 
the female of Geocichla sibirica (cf. Gloger, Isis, 1828, p. 1041), a misapplication repeated in 1840 
by Keyserling and Blasius (Wirb, Eur. pp. li, 178), partially corrected by Schlegel in 1844 (Revue 
Critique, pp. xl, 70), but not finally put right till 1872 by Cabanis in the ‘Journal für Ornithologie ’ 
for that year (p. 157). 
The oldest generic name for the present species would appear to be that of Zroreus of Bonaparte 
(C. R. xxxviii. p. 3); but he, as Mr. Sclater tells us (P. Z. S. 1859, p. 331), mistook the South 
American Myiotheretes rufiventris, of the family Tyrannide, for Turdus nevius. Jxoreus must be 
detached from G. nevius altogether, and placed as a synonym of Myiotheretes. 
The present species is placed in the genus J/esperocichla by the American naturalists, the 
characters being given by Dr. Stejneger (Proc. U.S. Nat. Mus. v. p. 465) as follows :—“ Body stout, 
only very little spotted. Wing much as in Turdus, the second primary, however, being considerably 
shorter than the fifth. Bill more subulate, narrow at the base, with considerably curved commissure 
and inflated tomia; genys long, being longer than half the commissure, which only very 
exceptionally has a subterminal notch. The covering of the nasal fosse is completely filled 
by feathers, and the openings of the nostrils concealed by a considerable number (about 7) 
of stiff bristles. Besides, the bristles along the gape are much more developed than in other 
Thrushes. "Tarsus stout, of moderate length, shorter than two-eighths of the wing, but still longer 
than the commissure ; outstretched legs falling far short of the tips of the tail. Hesperocichla
