From G.japonensis the present form differs solely by the size of the bill. 

 The culmea presents the same strong curvature (in contradistinction to 

 the more gentle bend of the culmen in C. corone) but the bill is con- 

 siderably lower throughout. 



Judging from descriptions this is the same form which Swinhoe col- 

 lected in Formosa and named Corvus colonorum.

Sturnia pyrrhogenys Temji. & Schl. 



I can discover no appreciable difference between the specimen sent, 

 which was collected by Mr. Nishi on Yayeyama Island, and typical 

 specimens from Northern Japan, except that the under tail coverts are 

 nearly pure white. There seems to be great variation, however, in this 

 respect. 



Zosterops japonica Temm. & Schl. 



It is impossible to say, from the single specimen collected by Mr. 

 Nishi at Yayeyama Island, whether the form occurring there is abso- 

 lutely identical with the typical Z. japonica, or whether it constitutes a 

 race of its own. 



In general coloration it agrees well with Japanese specimens, except 

 that the flanks are somewhat paler than average Z. japonica. The dusky 

 of the lores and under the eyes is of the same intensity as in the latter. 



There is, however, a considerable difference in the wing, which in the 

 Yayeyama bird is shorter, while in all the other fiimensions it agrees 

 with the ordinary type, the wiug being only 'S^V"™ against 58™'", the 

 average of 7 Japanese specimens. This shortness of the wiug is par- 

 ticularly due to the shortening of the primaries, the relative propor- 

 tions of which also differ from any Japanese bird I have seen, the wing-
