I have never seen any specimen of this genus from Greenland, 

 but I do not doubt that Forbes has named the specimen from 

 Godsir correctly. This suggestion is confirmed by the circum- 

 stance that Fabricius mentions Helix nitida, Miiller, as found in 

 Greenland. That Fabricius had found a species of Helicella, and 

 not Conulus, is evident from the following expressions : " H. ni- 

 tida testa umbilicata subdepressa, fulvo-cornea pellucida, sub- 

 striata, apertura larga." Fabricius was too good a pupil of 

 Miiller to take Comdus Fabricii without umbilicus for Helix ni- 

 tida. Fabricius would no doubt never have distinguished H. 

 Fabricii from Helix fulva, Miill., of which he has given a de- 

 scription and figure of the shell with the animal in the Transac- 

 tions of the Danish Academy of Sciences, 17^3, vol. iv, p. 98, t. 

 1, f. 3, from a Norwegian specimen, without mentioning that the 

 species was described in his Fauna. In his manuscripts which 

 contain corrections to his Fauna, he tells that he had afterwards 

 found H nitida in several places in Norway and Denmark, and 

 from the accompanying drawing it is evidently a Hyalina. 



Huius testans vacuam tantum submuscis rarissime offendi, 

 Fabr. It was found in Iceland by Prof. Steenstrup. 



As I in 1857 was unacquainted with H alliaria, I considered 

 the Icelandic specimens distinct, chiefly because the thick lacini- 

 ate epidermis and the descending suture* was not mentioned in 

 any species of that genus. It was found at Arendal, in Norway, 

 by Prof. Steenstrup.

 Pfeiffer confounded it even with the much larger, not umbilieated H. 

 glabra, Studer.
