Journal de Conchyliologie for 1873, also the northern shores of 

 the Black Sea, is poor in comparison with most of the others. The 

 characteristic group is Fruticicola, the subgenus of Helix, including 

 rufesce/is, hiipida, etc., and the small subgenera o^ Helix, Acanthi- 

 iiula and Vallotiia are also marked features. The other subgenera 

 of Helix are poorly represented. Xeropliila and Eiiparypha are 

 found in the littoral districts, as is also the subgenus Cochlicclla 

 represented by H. acuta, Miiller, the shell called Bulimus acutits 

 by Jeffreys and Pfeiffer. (It may here be remarked tliat the 

 Jamaican H. acuta. Lam. must change its name if Cochlicella acuta 

 is to be finally considered as a .Helix, we have seen acutissima 

 used in Paetel's catalogue, but as that name was given to a very 

 distinct variety, we prefer H. Lamarckii, Fer, for the species, the 

 other H Lamarckii being now universally included in Nauina). 

 The genus Hyalina is pretty largely represented in this region. 

 Pupa and Vertigo are also abundant, Bulinnnus has only a very 

 few species, Clausilia seems to die out to the north and west from 

 its centre of dispersion in the Balkan Peninsula, and throughout 

 the greater portion of the region Cyclostouius ehgans and one or 

 two species of Acme form the sole representatives of the opercul- 

 ate Pulmonifera. 



This region includes the greater part of Dr. Fischer's Western 

 Region which he makes to extend all along the coast of the 

 Atlantic from Ireland to Portugal, We can hardly agree with this 

 division. It is based upon the occurrence of certain peculiar 

 species. These, however, are mostly limited to peculiar localities, 

 whilst those species such as Helix pisana and variabilis which are 

 truly distinctive of the coast, as opposed to the inland, fauna are 

 also found throughout all the coasts of the Mediterranean. The 

 truth appears to be that these species are common to the coast of 

 the vt'hole province (except in the Arctic Regions), and, therefore, 

 unless a littoral region is to be formed, embracing the whole extent 

 of land within a league or two of the sea, hardly an advisable
