1880.] LAND-SHELLS OF MENTON, 119 



It answers well to the description of //. crimoda and //. concreta, 

 Bourg. loc. cit., of which it may be a large variety. 



Alt. 7, diam. 1 1 millim. 



Type var., Indian Museum, Calcutta. 



Helix (Fruticicola) di^ga, Bourg. (Rev. et Mag. Zool. 

 1877, Clus de St. Auban; alt. 6, diam. 1 1. Var. major, Briau9onnet, 

 Alpes-Marit. ; alt. 6^, diam. 1 14^ millim.). 



I am indebted to M. Bourguignat for two typical specimens from 

 the Col di Tenda ; Mr. Williams found a similar, though larger, form 

 on the " Grand Mont." I consider the species quite distinct 

 from H. nioutoni ; but it is very close to H. telonensis, from which 

 the white band at the periphery would not be sufficient ground alone 

 for specific separation ; the aperture, however, seems to me markedly 

 larger in proportion, with less broadly reflected peristome. 



Alt. 7^, diam. 12 millim. "Grand Mout." 



Alt. 6,'^diam. 10 millim. " Clus de St. Auban," ex coll. cl. Bour- 

 guignat. 



Helix (Fruticicola) telonensis, Mittre {fide Bourg., Rev. 

 Mag. Zool. 1877 ; alt. 5 to 5|, diam. 10 millim.). 



Scarcely, I think, specifically distinct from the preceding. M. 

 Bourguignat identified as this species several specimens (in poor 

 condition) from the " Grand Mont," at 4000 feet ; two subfossil 

 specimens from deposit B are even nearer the typical Toulon form. 



Alt, 6, diam. 104^ millim. Subfossil specimen from deposit B. 



Alt. 54^, diam. 9^ millim. Specimen from Toulon, 



Alt. 6g, diam. lOg millim. Specimen from "Grand Mont." 



Var. CRASsiLABRis, nov. 



A single specimen, in perfect condition, from the " Grand Mout," 

 quite distinct from all the forms mentioned by Bourguignat loc. cit. ; 

 chestnut-brown, with well-defined, broad, white belt at periphery ; 

 spire rather depressed, with six scarcely conve.'s, lightly striate 

 whorls ; compressedly angulate at periphery, base evenly rounded 

 (but not convexly swollen) round the unusually open umbilicus; 

 aperture very small comparatively ; peristome very broadly reflected ; 

 columella very oblique. Resembles //. diceya, with aperture of 

 H. telonensis. 



Alt. 6g, diam. 1 1 millim. 



Type var., Indian Museum, Calcutta. 



Helix (Cochlicella) acuta, Miiller. 

 Rather scarce near Menton, close to the sea. 



Helix (Cochlicella) Barbara, Linnajus. 

 Helix ventrosus, Fer. Vvod., = H, ventricosa, Draj). 

 Like the preceding, by no means common. 



Helix (Euparypha) pisana, Miiller. 

 Rare, near the sea only.
