had gone out expressly to do so. After this I should not be sur- 
prised if the Zoological Society were to send out an army to take 
the monster alive, for alive he most certainly is in my opinion.” 
A paper was then read from M. Petit de la Saussaye, in which the 
author describes the following new species of Shells, placed in his 
hands for that purpose by Hugh Cuming, Esq. Among these, M. 
Petit observes, are several which in his opinion form a new little 
group, possessing well-marked characters, and which might be re- 
garded as a subgenus, for which he proposes the name Hlasmatina*. 
These shells, which are all terrestrial, form a portion of the great 
family Helicide, and appear to be confined to certain islands in the 
Pacific Ocean. They are of small size, transparent and fragile, and 
their columella is always furnished at least with one tooth, and 
sometimes with several teeth, The chief characters are thus ex- 
pressed by the author :—
