Cinclus pallasii TemM. (247) 
It is extremely doubtful whether the name here employed is the cor- 
rect one, but inasmuch as it seems impossible at the present time to 
find out just to which form Temminck originally applied it, we may 
accept the name in common use, as the original Becaenen contains 
nothing which could seriously affect the identification. Temminck 
based the name upon a specimen which he received from Pallas at the 
time when the latter was in the Crimea. For that reason Temminck 
conjectured that the species occurred in that country. The variety 
which Pallas received from Baical (Zoogr. Ross.-As., 1, p. 426) is usu- 
ally quoted as belonging to C. pallasii, but Taczanowski insists (Bull. 
Soe. Zool. France, 1876, p. 58) that only C. leucogaster occurs in that 
locality. Pallas also states that he received specimens essentially 
similar from Kamtchatka and the Aleutian Islands through Billing’s 
expedition, but the Dipper does probably not inhabit Kamtchatka, 
and the species occurring in the Aleutian Islands is C. mexicanus. I 
regard it as very probable that Pallas had no specimens at all of the 
present species. 
Swinhoe’s C. marila (Ibis, 1860, p. 187) seems to be a smaller race of 
the present species occurring in Formosa, and a large and more richly 
colored form is indicated by Mr. Sharpe (loc. cit.) as occurring in China. 
There is a single specimen in Henson’s collection, No. 245, collected 
at Hakodate, December 12, 1885. It is a female, and, like other speci- 
mens from Yezo, it does not differ in any way from birds collected in 
Hondo. U.S. Nat. Mus. No. 120466. 
Hypsipetes amaurotis hensoni, subsp. nov. 
DraGnosis: Differs from typical Hypsipetes amaurotis (TEMM.) in 
being paler, the color of the flanks particularly so. 
HABirat: Yezo, Japan, migrating south in winter to Hondo.
