MlC'ROMYS AQUARIUS MANTCH URICUS ThoS. cf . 612. Fusan, S. Korea. 150'. cf. 613,615,634. ? . 614. Mok-pho. 200'. cf . 636, 637, 638, 644, 645, 646, 647, 648. 2 . 635, 639, 640 642, 643.

Quelpart Id. 3000-4500'. The extraordinary variation in this species renders its determination very difficult, and 1 use the above name only provisionally. For, on the one hand, further Manchurian material may bring out some difference between the Korean and Manchurian forms, and on the other it is possible that both will prove indistinguishable from the Chinese ningpoensis. In the present fine series, examples are to be found with strongly marked dorsal stripe and others almost or quite without it. In general colour, also, some are strongly rufous while others are grey. In character of fur we find here again, as in M. speciosus, the characteristic of the summer coat being spinous, while that of the winter is quite soft ; and to this rule no exception occurs among the present series. There does not appear to be any difference between the specimens from Quelpart and those from the Korean mainland-a somewhat remarkable fact, considering the distance out to sea, at which the island is situated. The occurrence of this species, which is wholly absent from any part of Japan, is conclusive evidence of the Korean rather than Japanese character of the Quelpart fauna. 7. M icromys m in u tu s ussuricus B. Ham. cf . 656. Min-gyong, 110 miles S.E. of Seoul. 1000'. cf. 737. 2 • 721. 10 miles N. of Taiku, S. Korea. These specimens agree with the type from the Ussuri in" the small size of their teeth as compared with the Japanese M. m. japonicus. They vary, however, a good deal in colour. 8.
