The glassy enamel, which gives a brilliant polish to the small, 

 terrestrial shells composing this genus, seems to distinguish them 

 even from those species of Cyclostoma which most nearly resemble 

 them, in having a pupiform shape, and a notch at the base of the 

 columella. The question has been asked, " Why not make this 

 marginal notch the criterion of the genus ?" The answer is found 

 in the following facts : first, the notch is found in Cyclostomata, 

 which have no other character in common with Pupince ; second, 

 that several Cyclostomata have a canal at the lower part of the whorl, 

 which if continued would form a similar notch ; third, that our 

 Pupina lubrica, which could scarcely be separated from the genus, 

 has but a very slight emargination. 



The first species described under this generic name was P. Ke- 

 raudrenii, published by Vignard in the ' Annales des Sciences,' 1829. 



Mr. Grateloup subsequently described P. Nunezii under the ge- 

 neric name Moulinsia, neither of these naturalists being acquainted 

 with the operculum. 



All the species here described, with the exception of P. antiquata 

 and P. Keraudrenii, were recently brought to this country by Mr. 

 Cuming from the Philippines.
