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 remarkable 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 F- 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. 11} millim., others diam. 19}, 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^EA) CINGULATA, Studer, var. BIZONA, Rossm. Icon. xi. fig. 683, 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. anconce, 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. bizona, which besides is from the immediate neighbourhood. Alt. Ilf, diam. 21} 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 mollusks 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 solid 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 m y subfossil var. primitiva; it is of thin texture, very variable as to the more or less |
