118 MR. G. NEVILI- ON THE [Feb. 17, 



Subvar. minor. 



A very smnll form from Roquebruue : can this be the H. clela- 

 courti, Mabille, of Bourg., whieli he informs me {in litt.) that I sent 

 him from Mentou ? He inserts the species between H. cemenelea and 

 H. ancoTKB. 



Alt. 7f, diam. \\^ 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 dis- 

 tinctly keeled. Judging from M. Bourguignat's description of his 

 //. ffuevarriana, 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 H. 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 depart- 

 ment 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 If. 

 moutoni, telonensis, or diaga ! 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., ^e?e 

 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. 7^, diam. 1 H millim. " Berceau" H. moutoni, fide cl. Bourg. 



Alt. 7|, diam. 12^ milHm. " 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.
