Helix (Xerophila) lineata, Olivi {=H. maritima, Drap., 

 alt. 8, diam. maj. 11, niiii. 9i millim.). 



Exceedingly abundant in the submaritime zone near Menton ; it 

 also occurred at Alassio. I found many curious varieties and 

 deformities ; the commonest forms are uniform brown, or white 

 with a broad brown band, both plentiful in all sizes. 



Subvar. major. Alt. IH, diam. 15; another — alt. lOg, diam. 

 1 3| miUim. 



Subvar. minor. Alt. 8, diam. 9 (a beautiful and rare form) ; 

 another — alt. 6|, diam. 9 millim. 



Helix (Xerophila) variabilis, Drap. (alt. 12, diam. maj. 

 19, min. 17, ex Pfeiffer, Mon. i. p. 157). 



I only found this species at Cape Vieille, between Roquebrune 

 and Monaco, where it appeared to be rather localized. 



Helix (Xerophila) pseudenhalia, Bourg. (Mai. Chateau 

 d'lf, pi. i. figs. 17-21, 1860; alt. 8-9, diam. 10-11 millim.). 



M. Bouvguignat regards this species as not belonging to the 

 group of H. maritima. I confess it seems to me scarcely separable, 

 even specifically. Menton specimens are subkeeled at the peri- 

 phery- 

 Alt. 7|, diam. 10| millim. 



Helix (Xerophila) neglecta, Drap. (alt. 7, diam. maj. 14, 

 min. 12 millim., ex Pfeiffer, Mon. i. p. 164). 



Very local at Menton, confined, as far as I know, to the neigh- 

 bourhood of Roquebrune station. 



Alt. 7g, diam. 12| millim. 



Helix (Xerophila) paladilhi, Bourg. (Moll. Nouv. &c. 

 1866, pi. XXX. figs. 1-5, Moutpellier ; alt. 4, diam. 7 millim.). 



I include this species, as Mr. Bourguignat informs me I sent him 

 a single specimen mixed up with H. candidula from Menton. 

 Mr. Williams found a single specimen of a closely allied species at 

 over 3000 feet on the " Grand Mont," which I am unable to iden- 

 tify ; it can scarcely be an extreme var. of this species. At Alassio, 

 however, I found two specimens of a very distinct little form, which 

 agree exactly with the original figure of this species. 



Alt. A\, diam. 7 millim. Specimen from Alassio. 



Alt. 5^, diam. 8j miUim. From the "Grand Mont;" specific 

 identification very doubtful. 



Helix (Xerophila) terrestris, Chemnitz (alt. 6^, diam. 

 maj. 10, min. 9, ex Pfeiffer, Mon. i. p. 179). 



Extremely abundant at Menton, where I found many curious 

 forms, some much distorted. M. Bourguignat writes me that I 

 sent him one very curious abnormal specimen, "having the ordinary
