and on the resultant increase in our knowledge of geo/^raphical 

 zoology, a subject in whose study the Zoological Society had 

 always had so large a share. 



A conii)lete list of the specimens would be given later, but in 

 the meantime Mr. Thomas gave the following account of the 

 new forms* : — 



]\ I vox IS MYOSOTIS ANCILLA Thos. 



Abstract P. Z. S. 1910, p. 25 (April 2G). 



Smaller, with shorter ears, ami more drab-cfjlourod than in 

 true ))ti/osoiis. 



Size rather smaller than in mijosotis, not so small as in hh/thi. 

 Ears decidedly smaller than in mj/osotls. General colom- above 

 nearly api)roaching " drab " of llidgway, very different from 

 the " wood-brown " of myosotis and its pale Persian subspecies 

 omari. Head rather greyer. Dark shoulder-patches moi-e 

 strongly defined than in Dii/osotis, blackish brown. Under 

 surface as in myosotis. 



Skull slightly smaller than in myosotis, and the bulla; smaller 

 in correlation with the .shorter ears. Protocone apparently as 

 in myosotis, not as described by Miller in blythi t. 



Dimensions of the type, the starred measurements taken in 

 the flesh :— 



Forearm 61 nun. (range 59 to (32). 



Head and body *75 mm. ; tail *5() ; hind foot *12 ; ear *21. 



Skull : greatest length 22-2, basi-sinual length 17, front of 

 canine to back of m^ 9'2. 



Jlab. Shang-chou, S.E. Shen-si. Alt. 3300'. 



7'i/pe. Adult male. B.M. No. 10.5.2.4. Original number 2082. 

 Collected 27 November, 1909. 



This is the eastern representative of the common European 

 M. myosotis. What its relationship is to the Indian form blythi 

 remains to be seen when better specimens of the latter are 

 available foi" examination. l>ut the type of J/, blythi, received 

 in the British Museum in the Tomes collection, is decidedly' 

 suialler. 



MiCROTUS (EOTHENOMYS) NUX ThoS. 



Abstract P. Z. S. 1910, p. 26 (April 2()). 

 Darker than M. inez, with a longer and more distinctly bicolor 



tail. 



(leneral colour above decidedly d.u-kcr ili.iu in /y;?',:, the back 

 approaching " Prout's brown"; under surface also brown, of a 

 slightly more bufiy tone than the upper surface, but not .sharply 



* The complete Jiccount of tlie new species (k'scril)C(l in this conHnuniiatioii 

 appears lieve, hut since the names and ]>iehminiir.v diaiinoses wi-re pMl)lisheil in the 

 ' Ahstnict,' No. 83, 1910, these spevies are distinguished hy the names being under- 

 lined.— Kj>rroK.
