1880.J LAND-SHELLS OF MENTON. 139 



distinctly sinuated sculpture ; the last whorl, scarcely convex, is 

 somewhat abruptly augulate (or furrowed) at the columella, and 

 agani very delicately and more or less obsoletely (requiring careful 

 examination with a lens to detect) just below the suture, ter- 

 minatmg in the labial incision ; these two furrows correspond, of 

 course, with the sculpture ; the aperture is always more or less 

 contracted, especially at its base j within, the peristome is thickened 

 with a white callosity, terminating at the sinus. I should describe 

 the columella as twisted and contorted ; but Monsieur Bourguignat 

 maybe perhaps more correct in saying:—" Columella offrant a sa 

 partie superieure un renfoncement canaliforme, ce qui la fait paraitre 

 vers le bas comme torsee et lamellee." The species varies very 

 little; there is a slightly dwarf emaciated form, with the spire 

 twisted like some of the Eulimce, and with the aperture even more 

 contracted. 



Type, Indian Museum, Calcutta; also in coll. J. R. Bourguignat 

 Coombe Williams, P. Joly, and Colonel Godwin-Austen. ' 



The specimen figured has been since accidentally broken. 



PoMATiAs PATULus, Drap., (?) var. Montana, Issel. 



An abundant and somewhat variable species on the " Grand Mont" 

 and " Berceau," at 3000 to 4000 feet. Very likely this is the var. 

 montana of Issel. 



Long. 8, diam. 3f millim ; another, long. 6^, diam. 3| millim 

 " Grand Mont." 



Pomatias septemspiralis, Razoum. 



An exceedingly common subfossil species in deposits A, B, C, D 

 E, and F. I did not find it myself associated with H . paretiana ■' hnt 

 AI. Bourguignat did so in a cutting of the railroad at Cape Vieille 

 We did not find the species hviug ; nor is it recorded from the Depart- 

 ment by Risso. Mme. Paulucci, however, records a var. turricula 

 from the Alpes Apennines, in her ' Faune Mai. Italic,' which will 

 probably prove identical with this subfossil variety ; in any case it is 

 quite a distinct form from Swiss specimens of this species, in which 

 the umbilicus is completely covered, the more convex whorls less 

 turriculate, the last much less broad in proportion, the aperture less 

 everted, the sculpture of the last whorl similar to that of the pre- 

 ceding ones,instead of being finer, more crowded together, niore 

 flexuous and less oblique, &c. I found endless varieties of the 

 Menton form ; but all preserve a totally different aspect from their 

 more northern (and typical) form. 



Long. 7^ to 8, diam. 3^ to 4 millim. The commonest form. 



Long. 8|, diam. 3| millim. A subvar. major. 



Long. ^, diam. 3| millim. A not uncommon subvar. nana. 



Pomatias hercul.eus, Bourg. MS. (Plate XIV. fig. 8.)
