A well-differentiated species, by the lack or very small size 

 of teeth, recalling the Sicilian G. rupestris and the Algerian 

 G. du-poteti, yet not closely related to either. 



The distribution of farinesii has been worked out by Mar- 

 gier and Caziot. It is generally distributed in the dep. Pyre- 

 iiees-Orientales, and occurs also in the Spanish Provinces of 

 Gerona and Barcelona. There is a record from Portugal, no 

 doubt erroneous. In France it extends northward from the 

 dep. Pyrenees-Orientales through Aude, Tarn, and Averyron 

 to Lozere, that is, along the Cevemies uplift (using this term 

 in a wide sense) . There is even a single record from Langogne 

 (dep. Allier), but I regard this as dubious, since the Abbe 

 Dumas, who seems to have collected assiduously, did not find 

 it (Rev. Sci. du Borbonnais, 1901). It is very local in these 

 eastern departments, special localities being on limestone 

 rocks of the gorge of Malefosse, of the Tarn, as far up as Bla- 

 joux. M. Locard found specimens in flood debris of the 

 Rhone, doubtless washed in from a western affluent. There is
