1880.] LAND-SHELLS OF MENTON. 115 



Type in the collection of Mons. Bourguignat ; types of var. and 

 subvar. in the Indian Musen m, Calcutta; also in the collections of 

 MM. Bourguignat and Coombe Williams. 



Helix (Campyl^a) ramoriniana, Issel, Conch. Cav. Ligur. 

 occid. 1867, figs. 4-6. 



An interesting rediscovery of this well-characterized and re- 

 markable species, as yet only known from the cavern at Verezzi. 

 I found no traces of the species about Menton, except some half 

 dozen specimens in deposit i^— that is to say, at the entrance of the 

 cave. Probably the species was a strictly cavern form. 



I compared the Menton specimens with Prof. Issel's types in the 

 museum at Genoa ; they are exactly similar, except that mine are a 

 trifle larger. My largest measures diam. 22, alt. Ill millim., 

 others diam. 19i, alt. 10. I ought to mention that Prof. Issel's 

 above-quoted figures are not very successful ; indeed the species is 

 not recognizable from them. 



Indian Museum, Calcutta ; also in coll. Mons. Bourguignat. 



Helix (Campyl^a) cingulata, Studer, var. bizona, Rossm. 

 Icon. xi. fig. 083, from near Nice. 



Mr. Williams found a single specimen at Sainte- Agnes, at a little 

 over 2000 feet. M. Bourguignat informs me it is true H. cingulata, 

 and that he found the form abundant in the Col di Tenda. 



I can hardly bring myself to believe this form specifically identical 

 with a shell sent me, as H. cingulata, var. anconcB, Gentiluomo, 

 from Tuscany. The Menton specimen has a moderately raised 

 spire, rather shallow umbilicus, last whorl not compressed, descending 

 abruptly, convex at base ; aperture nearly square, columellar margin 

 scarcely oblique ; both zones are somewhat obsolete, the lower one 

 can only just be traced behind the outer lip and in front near the 

 aperture. The above agrees exactly with Pfeiffer's measurements and 

 characters of var. hizona, which besides is from the immediate neigh- 

 bourhood. 



Alt. I If, diam. 21i millim. 



Pfeiffer's measurements (Mon. i. p. 356) of var. bizona are — 

 diam. maj. 24, min. 21, alt. 12 millims. 



Indian Museum, Calcutta. 



Helix (Macularia ?) niciensis, Ferussac. 



This appears to have been one of the most characteristic moUusks 

 of Menton in old days, as it is now, and to have changed very little 

 during all the intervening period. 



Mr. Williams found a few living specimens at Sainte-Agnes, 

 at a little over 2000 feet, a fine bold form of sohd texture and 

 rich coloration. Higher up, between 3000 and 4000 feet, to the 

 very summits of the " Berceau" and " Grand Mont," H. niciensis 

 abounds. The form here approximates nearer to my subfossil var. 

 primitiva ; it is of thin texture, very variable as to the more or less
