 is vi. and vii. 



Directions of Var. (a.) size : average specimens from the -Jura 

 are said by h'lir. and M.-D. to be larger than those from the 

 Alps, but are certainly not larger than those from the neigh- 

 bourhood of the Rhone Valley. Specially flne above Susa, vi.

 with some of the Spanish examples from the Albarracin 

 district {( '///*.).]
