Hoist obtained the Osprey on the Tsushima I;?lands 

 (Seebohm, Ibis, 1892, p. 95). Jouy also collected it on the 

 same islands, 25 May, 1885 (Clark, Proc. U.S. Nat. Mas.

Nineteen specimens of adults and some young of this 

 Pheasant were shot by Mr. Teraoka on both islands of 

 Tsushima, Sept. 29-Oct. 29. Wing: in 10 adult males, 

 226-243 mm. : in 9 adult females, 196-206 mm. It is very 

 common on the islands, especially so on the northern 

 island. Dr. Ijima stated that the Pheasant was introduced 

 into the northernmost island, Unishiina, Tsushima, from 

 Corea in the Middle Ages, whence it spread over both 

 islands (see Ijima, p. 127). 



I carefully examined the series of males of the specimens 

 from Tsushima and those from Corea for the purpose of the 

 identification of the two subspecific names above men- 

 tioned. I have come to the conclusion that the series of both 

 forms before me no doubt belong to one subspecies, and 

 cannot be separated into two forms as Mr. C^lark believed. 

 The following five points are the results of my study, and 

 show the reasons why the two forms cannot be separated : — 



(i.) The colour of the mantle and flanks of the males in the 

 supposed two forms is variable in the same stage and even in 

 the same locality ; (ii.) the width and colour of the eyebrow 

 are variable (in some almost white, in some bufi'y, and in 

 others white suffused with buffy) from the same locality. 

 A specimen from northern Corea has its eyebrow white and 

 distinctly suffused with rusty colour ; (iii.) the colour of the 

 crown is also variable in the same locality ; (iv.) the colour 

 and barring on the central tail-feathers are also indefinite 

 in individuals ; and (v.) the degree of archness of bill is 

 variable, though the examples from Tsushiir.a have their bill 

 on an average slightly more arched than those of Chorea, but
