318 On a new Species of Shrew from Corea. 
Crocidura lastura (P. Z. 8. 1906, p. 860), of four specimens 
of which he gives the following measurements :— 
“ Four adult specimens from Min-gyong measure : 
Head and body. Tail. Hind foot.

In comparing these two sets of measurements it will at 
once be seen that there is a very considerable difference in 
the sizes of the Corean and Manchurian shrews, and, since 
my specimens undoubtedly belong to Dobson’s Crocidura 
lasiura, it would seem that Mr. Anderson’s Corean specimens 
represent an unnamed species. After corresponding ‘with 
Mr. Thomas on the subject, and finding that he agrees with 
me in the matter, I have decided to separate the ean form, 
and since Mr. Thomas has done so much in working out the 
mammals of Hastern Asia, particularly in the Insectivores, I 
would propose to name this species in his honour 
Crocidura thomast, sp. n. 
This shrew may be described as closely resembling C. 
lasitura in colour and general appearance, but , differing 
markedly in point of size, being very much smaller. 
The only tully adult specimen of C. lasiura taken by me 
in Manchuria has a head and body measurement of 104 mm., 
tail 48, hind foot 16°5, as compared with 83 mm., 40, and 15 
in the largest of the Corean specimens. 
Proportionately, also, the tail in C. thomas? is shorter than 
in C. lasiura. 
Colour. My. Thomas says the Corean specimens agree fairly 
well with Dobson’s déscription, so we may presume that the 
colour is about the same, though I have not been able to 
ccmpare specimens. C. lasiura ‘is of a very dark blackish 
slate, only very slightly lighter on the under surface *, 
Dimensions of type (measured i in the flesh) :— 
Head and body 83 mm. ; tail 40; hind foot 15; ear 9°5. 
* [C. thomas? is paler than the above would suggest, the type scarcely 
darker and greyer above than Ridgway’s “drab,” neutral grey below.—
