MR. W. T. BLANFORD ON THE 



[Mar. 18, 



many broad valleys, separated by minor ridges, a central plain is 

 reached at an elevation of about 3000 feet above the sea. Gazella 

 subgutturosa inhabits especially the valleys and plains between the 

 mountain-ranges from about 3000 to 7000 feet, ranging higher in 

 summer and descending to lower elevations in winter, but keeping 

 generally within the limits I have named. To what extent it extencjs 

 over the central desert I am unable to say ; but it probably occurs 

 through a large portion of it, unless it is replaced by the new species 

 presently to be described.

 To the north-west this Gazelle is certainly found as far as Tabriz,
