the one and zarudnyi, arenicolor and cinctiira on the other hand are too 

 6triking — too qualitative, Dwdght would say — and that therefore " Ammo- 

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

 cinctura," ".4. cinctura arenicolor^'' and ".4. cinctura zarudnyi." 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 quahtative and what quantitative 

 is often most difficult ! It is remarkable that a specimen collecU>l south of 

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

 deserti (!) is typical zarudnyi !)
