I/arvrsl-Mtiusf aud its UfOi/rajiliic'il Wiritilinns. 5*29 



I. Mus 7niniitus li/picus, P. S. I'allas, Nov. Spec. pp. 9() .t 31.5 



(1779). 



Ilab. Siberia. 



I have seen no speciint'ii of this t'orin. 



II. }fus mi'nutus ae/ilis (J. F. A. Delinej, IIofloS3nitz, p. IG 



(1841). 



Hab. Northern Europe (specimens seen tVoin Hninswick). 



Distinguishing c/uinicteristics. The up])orside is not so ro 1 

 as in M. m. viinintun, but the colour is uniformly distributed, 

 there being no contrast between the rump and the upper 

 dorsal region ; the underside is strongly washed with yellow, 

 hence the line of demarcation between the colours of the two 

 surfaces is not so distinct as in .1/. ?«. 7nini>nus', the tail ex- 

 ceeds the combined length of the head and body ; the hind 

 foot seems to be larger than that of J/, in. viininius. Young 

 specimens have a duller and more niuscuIus-WkQ coloration 

 of the upperside, and in some cases a less richly tinted under- 

 side than the adults. 



The dimensions of an adult female (no. 85307*) reach (in 

 millimetres): — Head and l)ody 68; tail 76; hind foot 16; 

 skull 18*5x8. The skull of a male (no. 85o65*) reaches 

 18 X 8*5 millim. These are the two largest of the thirteen 

 specimens from l^i unswick ; l)ut in all the teeth are unworn. 



III. Mus ntiiiutus canipesfris, A. G. Desmarest, Mamm., 

 Suppl. p. o43 (1822). For svnonymy see Ann. & Mag. 

 Nat. Hist., April 18i>9, p 345. 



Hub. Probably Northern France, Belgium, and Central 

 AVestern Continental Europe (specimens seen from Warenne, 

 Belgium). 



DistinguisliiiKj characteristics. As compared with M. m. 

 minimus the upperside is almost or quite as red in colour, 

 but of more uniform arrangement, the contrast between runi[) 

 and upper dorsal region being absent ; the underside is 

 yellower, but less so than in M. m. agil/s; the line of demar- 

 cation is only moderately distinct. 



The dimensions appear to be similar to those of M. ni. agllis, 

 those of an adult suckling female (no. 86U00*) reaching: — 

 Head and body 65 millim.; tail 70; hind foot 16; skull 

 17x8.
