1880.] LAND-SHELLS OF MENTON. 127 



Type, Indian Museum, Calcutta ; also in coll. MM. Bourguignat 

 and Williams. 



Pupa (Torquilla) secale, Drap. 



Recent specimens were abundant near the summit of the " Grand 

 Mont," at 4000 feet. 



Long. G|, diam. 2| millim. 



In coll. Indian Museum, J. R. Bourguignat, and Coombe Williams. 



Pupa (TouauiLLA) avenacea, Brug. 



Living abundantly, with the preceding, at 4000 feet ; we also 

 found it, but rather scarce, in deposits B, C, and F. 

 Long. 7, diam. 2| millim. From the "Grand Mont." 

 Long. 7^, diam. 2| ; another, long. 5, diam, 2 millim. De- 

 posit B. 



Pupa (Torquilla?) grana, Drap. 



Avery common form everywhere in the Submaritime zone ; it did 

 not occur subfossil or at higher elevations. I much doubt if this 

 species is a true Torquilla ; 1 believe the animal will prove to be 

 of a different type ? 



Var. 



A rather scarce form, living in shady and damp localities ; it may 

 possibly be a distinct species, perhaps the P. micheli, with which I 

 am not acquainted. 



Pupa (Orcula) doliolum, Brug. 



Rare, at a single spot in deposit B : this is the first record of this 

 species in the Alpes-Maritimes, it is not mentioned in Risso's work. 



In coll. Indian Museum, Calcutta, J. R. Bourguignat, and Coombe 

 Williams.
