Show 124 MR. G. NEVILL ON THE [Feb. 17, Long. 11|, diam. 4\ millim. An elongate, more or less compressed form, not uncommon in the submaritime zone. Long. 13, diam. 4 | millim. The ordinary Menton form. Long. 9}, diam. 3 | millim. A small and rather convex form, rather scarce here. BULIMINUS (CHONDRULA) NISO, Risso. Apparently very scarce; I found five or six subfossil specimens only in deposit B ; they agree in being a small, more or less sub-convex form, with the columellar dentition quite different from that of the preceding. Long. 10, diam. o\ millim. Indian Museum, Calcutta. PUPA (PUPILLA) MUSCORUM, Linnaeus. A few specimens from deposit F only, all of them possessing a parietal tooth. The species did not occur recent at Menton ; but I found very similar specimens to the above subfossil ones at Alassio. Long. 3 } millim. PUPA (PUPILLA) UMBILICATA, Drap. W e did not ourselves find this species at Menton; but I saw specimens in the small museum, found just outside the town. I found a curious variety of it at Alassio. PUPA (VERTIGO) MINUTISSIMA, Hartm. I found only two broken specimens in deposit B ; the whorls were very convex and tumid, no parietal fold (or tooth) ; I think, only 5 whorls. Var. (? sp. distinct.). Three broken specimens from deposit B, differing conspicuously from the preceding ; six whorls, much less convex and tumid, giving the form an attenuate appearance; the aperture has a strongly developed parietal fold ; the striation seems more oblique. Both of the above (subfossil forms) in Indian Mus. Calcutta. PUPA ? (TORQUILLA ?) PSAROLENA, Bourg. Originally described as Bulimus, sp. Rossmiissler, Ic. vol. iii. 1854, fig. 929, who figures the species as Bulimus cinereus, Mortillet, Cat. Coq. Nice, 1851, between the Col di Tenda and Nice (that is, just behind Menton), notices its affinity to species of Torquilla, and hesitates in which genus it should be classed. When I found my single very perfect specimen in deposit B, I felt no doubt of its being an edentulate species of Torquilla, and have not altered m y opinion since M . Bourguignat gave m e some typical living specimens. M y subfossil specimen differs not a little from the latter, resembling still more strongly species of Torepiilla ; whorls distinctly 7, more elongately, regularly produced, the last one not so convexly tumid ; in proportion the aperture a little shorter and less |
