Show 118 MR. G. NEVILL ON T H E [Feb. 17, Subvar. MINOR. A very small form from Roquebrune : can this be the H. dela-courti, Mabille, of Bourg., which he informs m e (in litti) that I sent him from Menton ? He inserts the species between H. cemenelea and II. anconce. Alt. 7f, diam. Ilf millim. HELIX (FRUTICICOLA) CILIATA, Studer. I only found two specimens of this interesting species in deposit B; both agree in differing from recent Swiss specimens (received from Madame Vimart), having the aperture more laterally produced (that is, broader in proportion to its height), the last whorl more dilated, the base less convex, and the periphery slightly more distinctly keeled. Judging from M. Bourguignat's description of his II. guevarriana, from the neighbouring Col di Tenda, these Swiss specimens answer exactly to his description of his new species, and my Menton subfossil ones to that of his II. ciliata. Alt. 5, diam. 9 millim. HELIX (FRUTICICOLA) CINCTELLA, Drap. A single perfect specimen and some fragments, from deposit B. Both this and the preceding are recorded as living in the department by Risso. Alt. 8, diam. 12 millim. HELIX (FRUTICICOLA) GELIDA (?) Bourg. (Rev. et Mag. Zool. 1877, Mountain behind Brianconnet, Alpes-Marit.; alt. 7, diam. 10 millim. Also subfossil from " Cap Vieille," near Roquebrune.) M . Bourguignat kindly identified as this species three specimens from the " Berceau " (3500 feet); they do not, however, answer well to his description, being more narrowly umbilicate than H. moutoni, telonensis, or dicega! I should have classed them as a sub-variety of H. telonensis, Mittre. Alt. 6, diam. 10 millim. HELIX (FRUTICICOLA) MOUTONI, Mittre, MS. (Rev. Mag. Zool. 1877, "Ascros," Alpes-Marit., &c.; alt. 6, diam. 10 millim.,/^ Bourg.). I am indebted to M . Bourguignat for his identification as above of this form, which appears to be not rare on the " Grand Mont" and " Berceau," at 3000 to 4000 feet. Alt. 7f, diam. 11x millim. " Berceau" H. moutoni, fide cl. Bourg. Alt. 7f, diam. 12} millim. " Grand Mont." Var. SUBFOSSILIS, nov. A single subfossil specimen, from deposit B, differing from every other specimen of this group that I know by its exceedingly narrow perforation; the collumella is more oblique than in the preceding. |
