Mr. Cockerell respectively subdeleta and subscalaris. I also 

 found the forms fasciata and lutescens, all of which I exhibit 

 here to-night. 



The little Helix trochoides is a mountain species under 

 stones. You will observe both the type and the variety 

 fasciata. 



In the same localities, but only under very large stones, I 

 found the curious Stenogyra decollata, with its mutilated- 

 looking shell. As you will see in one very small specimen, 

 the top of the shell seems to be intact in its younger state, 

 but is beheaded at a later date, for the more mature shells 

 are never perfect. In the new museum of Toulon the smaller 

 forms are named var. minima ; but there seems no reason to 

 think that they are other than growing shells. 



Helix pisana\% very abundant along the seashore on dry 

 banks and cliffs, It appears in great variety, several forms 

 of which I exliibit. These run one into the other very closely, 

 but are not difficult to sort out with a little practice. 



By searching garden walls, of which there are far too many 

 around Toulon to please a naturalist, we find Pupa cinena. 

 well named from its burnt and faded appearance. In a like 

 locality, by the side of a stream, I found Clausilia bidens in 

 abundance hybernating in crevices. 



Everywhere we find examples of the very pretty Cyclostoma 

 elegansy so well known to you as inhabiting limestone and 

 chalky places in England. Of this species I got the forms 

 pallida and maculosa. 



The curious little shell of Pomatias patula is found at the 

 foot of rocks, both near the sea and all the way up to a 

 considerable height up the mountains. In some places it is 

 not common, but in others more favourable it is in great 

 abundance. 



I think I have said sufficient about my exhibits to draw 

 your attention to the subject of collecting shells when away 

 from home as a very charming addition to any other pursuits 

 we may follow more particularly.
