Ko. 1539. NEW BIRDS FROM EASTERN ASIA— CLARK. 469 



stripes broader and more conspicuous, beginning on fore part of crown 

 (where they are separated by a tongue of dark green feathers from the 

 forehead, equal to them in width) and extending to the nape. The 

 bill is slightly shorter with the cidmen more arched than in any of the 

 seven specimens of Ph. Ic. Icdrpowi before me. 



This subspecies represents Ph. l\ Ixirpoivi on the Tsushima Islands 

 in the straits of Korea, where it is common. 



LAGOPUS JAPONICUS Clark, new species. 



Type. — Cat. No. 121179 U.S.N.M.; male, mountains of central 

 Hondo, Japan; July 7, 1888; M. Kikuchi, collector. 



This is a very dark form of the Lagopus rupestris group, in general 

 appearance being most like L. ridgwayi Stejneger. It differs from 

 specimens of that species taken in July in having the vermiculations 

 of the upper surface much coarser and light buff in color instead of 

 deep rusty. On the breast, sides, and flanks this species is even darker 

 than L. ridgwayi, approaching L. evevTnanni Elliott; but what few 

 markings there are are light buff and much coarser than in either of 

 these species. 



LAGOPUS RUPESTRIS CHAMBERLAINI " Clark, new subspecies. 



Tyjie.—C&t.No. 131867 U.S.N.M.; male, Adak Island, Aleutians, 

 July, 1893; C. H. Townsend, collector. 



This subspecies is nearest to L. r. townsendi Elliott, of Kiska 

 Island, from which it differs in its finer vermiculations above, which 

 give the bird a grayer appearance, and in having the conspicuous 

 black bars on the neck and upper back of the Kiska bird reduced to 

 very narrow bars or vermiculations, the whole plumage presenting a 

 much more delicate pattern. The pattern on the breast, sides, and 

 flanks resembles that found in L. r. atkliensis Turner, but the ground 

 color is more grajdsh. In the character of its markings L. r. chamber- 

 laini is intermediate between L. r. townsendi and L. r. atkliensis, but 

 in general coloration it is much grayer than either, being the grayest 

 of all the Aleutian ptarmigan. The female of L. r. chamherlaini is 

 very finely marked above and below, resembling in this respect the 

 female of L. r. atkhensis, but it is very much grayer than that bird 

 above, and duller and less rufous beneath. The female of L. r. 

 townsendi is heavily barred beneath, most nearly resembling the 

 female of L. evermanni of Attn, of which the male is sooty black. 



It is interesting to note that this, the grayest and one of the lightest 

 of the Aleutian ptarmigan, occupies a position in the center of the 

 Aleutian chain; on either side the birds become more rufous (L. r. 

 atkhensis on Atka to the east, and L. r. townsendi on Kiska to the
