In comparing these two sets of measurements it will at 

 once be seen that tliere 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. Tiiomas on the subject, and finding that he agrees with 

 me in the matter, I have decided to separate the Corean form, 

 and piuce Mr. Tiiomas has done so much in working out the 

 mammals of Eastern Asia, particularly in the Insectivores, I 

 would propose to name this species in his honour 



Crocidura thomasi, sp. n. 



This shrew may be described as closely resembling C. 

 lasiura in colour and general appearance, but differing 

 markedly in point of size, being very much smaller. 



The only fully 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. tliomasi is shorter than 

 in C. lasiura. 



Colour. Mr. Thomas says the Corean specimens agree fairly 

 well with Dobson's description, so we may presume that the 

 colour is about the sanie, 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 in the flesh) : — 



Head and body 83 mm. ; tail 40 ; hind foot 15; ear 9"0. 



* [C thomasi is paler than the above would suggest, the type scarcely 

 darker and irrever above than liidgway's " drab," neutral grey below. —
