100 Mr. N. Knvoda on the Birds of [Ibis, 



Specimens from Corea, northern Kiusiu, and Amami- 

 osliima were examined by me, but they are too few in 

 number for exact identification. But it seems probable 

 that the example from Corea is almost identical with that 

 of Quelpart Island, thou oh the tarsus is a trifle shorter. 

 A specimen from northern Kiusiu is approximately iden- 

 tical with this new form, though here too the tarsus is a 

 trifle shorter. A specimen from Amamioshima is probably 

 identical with that of Yakushima, one of the southern islands 

 of Kiusiu. 



In Tsushima the new form is very common, and no doubt 

 it breeds there. Mr. Clark mentioned it as a common 

 breeding resident on Tsushima (/. c. p. 172). Dr. Ijima 

 (p. 110) and Seebohm (Ibis^ 1892, p. 91) both reported 

 this Tit from Tsushima. Seebohm and Clark mentioned 

 the species in Corea. It is probably a winter visitor from 

 Japan, but I have specimens of this species from Corea 

 taken during the breeding-season. 



115. Periparus ater teraokai, subsp. nov. 



Diagnosis. — Similar to P. ater insularis from Hondo 

 (probably from N. Kiusiu), but the culmen decidedly longer 

 and the coloration of the upper parts deeper. The occipital 

 feathers only 12 mm. long. 



The type-specimen was obtained by Mr. Teraoka at Nita- 

 mura, Tsushima, Oct. 6. It is an adult male, preserved in 

 my collection. 



The subspecific name is given in honour of the collector.
