the one and zarvdnyi, arenicolor and cinctura on the other hand are too 

 striking — ^too qualitative, Dwight would say — ^and that therefore " Ammo- 

 manes phoenicura " should be kept specifically separate from " A. cinctura 

 cinctura," " A. cinctura arenicolor '* and " A. cinctura zarvdnyi." Admitted 

 that I have, in this case and in several others, taken rather a wide view of species, 

 it cannot be denied that the similarity between the two groups is striking, 

 and may as well be called quantitative ; it is in any case of interest to have 

 pointed this out, and the decision of what is qualitative and what quantitative 

 is often most difficult ! It is remarkable that a specimen collected south of 

 Sehwan in Sind, 21. xii. 1875, by W. T. Blanford, and by him called Ammomanes 

 deserti (!) is typical zarvdnyi !)
