it in great quantities in the cultivated fields l . Eozet has indicated 

 its occurrence in the neighbourhood of Oran 2 . Loche found it 

 about Algiers ; and, finally, Lataste 3 himself took it in the plain 

 of Mitidja, at Arba, near Algiers, and in the fields of Azesga, to 

 the north-east of Fort National, " en Kabylie." Lataste did not 

 find it so commonly as Eozet would have led him to expect, and 

 he supposes that that author had confounded several other species 

 with the present one. 



This species is not included in Lataste's work on the Mammals 

 of Tunis \ so that I presume that it does not occur in that country. 



General Remarks. Lataste 5 states that sometimes the back shows 

 " d'un brun plus terne, et le gris domine sur les faces inferieures," 

 which variation appears to be produced especially in the " pays 

 meridionaux," and he has noted this variety also from Cardillac, 

 Gironde, France, from Ciudad Eeal, Spain, and from Algeria. 

 Side by side with this he states that he has met some individuals, 

 generally young, which in coloration only were indistinguishable 

 from common Mice. He adds (footnote) that these colours get 

 clearer in alcohol, and after a time such specimens in alcohol are 

 indistinguishable from the normal specimens. 



12. MUS SYLYATICUS TAUEICUS, Subsp. UOV. 



Mus sylvaticus, C. G. Danford and E. E. Alston, P. Z. S. 1880, 

 p. 62. 



Type. No. 77.8.13.9 (in alcohol) (British Museum Collection), 

 from the Zebil Bulgar Dagh, Asia Minor, collected by Mr. C. G. 

 Danford, on the 5th January, 1876. 



Distinguishing Characteristics. This single specimen from Asia 

 Minor cannot be identified with any known form of Long-tailed 

 Eield-mouse. It cannot be placed either with the large Mice of 

 Eastern Europe, or with the not very much smaller M. s. arianus 

 of Asia. The skull, although the teeth are worn, has a total length 

 of only 23 mm., and is thus smaller even than the smallest 

 Western European subspecies. 



Distribution. Uncertain : only known from the type specimen. 



General Remarks. Perhaps the nearest ally of this little Mouse 

 is M. s. algirus, another little known subspecies. It may be a 

 parallel form to the small "Weasel of the Caucasus and Asia Minor, 

 to which I have recently given the subspecific name of M. nivalis 

 caucasicus.
