On a new Species of Zosterops. 273 



XXVI. — Description of a new Species of Zosterops from the 

 Seven Islands, Japan. By Henry Seebohm. 



Zosterops stejnegeri, sp. n. 



Mr. Hoist has sent me three skins of a Zosterops which 

 differ so much from the Japanese species that they must be 

 regarded as specifically distinct. They were shot on the 21st 

 of November last on the island of Fatsizio or Hatchi- 

 now-sima, one of the Seven Islands south of Yokohama. 

 In the colour of the upper parts they resemble Zosterops 

 simplex and Zosterops japonica, but in the colour of the 

 underparts they are intermediate between the two species; 

 the breast and flanks are not so grey as those of the Chinese 

 species, but are much less ruddy than those of the Japanese 

 species. In size they exceed both the allied species, as the 

 following measurements prove. The Chinese species is found 

 on the Loo-Choo Islands_, where the average size is so much 

 larger than is usual on the continent that it has been de- 

 scribed as distinct under the name of Zosterops loochooensis 

 (Tristram^ Ibis^ 1889^ p. 22S) . The examples from Fatsizio 

 are, however^ much larger than this large race. Two of the 

 skins are poor, but one is in very good condition, and shows 

 a great deal of black on the lores and under the eye. 



The culmen of the new species varies from '75 to "8 inch J 

 measured from the frontal feathers from '55 to '59 inch. 



Examples from the Loo-Choos vary from '54 to "6 inch ; 

 measured from the frontal feathers from '4 to "42 inch. 



Examples from Japan and China vary from '51 to 'Q\ inch ; 

 measured from the frontal feathers from '39 to "42 inch. 



In length of wing the new species varies from 2-5 to 2*55 

 inches, the Loo-Choo race from 2*15 to 2*25 inches, the 

 Japanese species from 2*2 to 2*4 inches, and the Chinese 

 species from 2*1 to 2*25 inches. 



I have named this species after my friend Dr. Stejneger 

 because he has done so much for Japanese ornithology, 

 and because there seems reason to think that the Zosterops 

 obtained on Oshima by Mr. Namiye may belong to this 

 species (Stejneger, Froc. U.S. Nat. Mus. 1887, p. 486).
