352 Catalogue of Terrestrial and [June, 



of Helicigona, and to the 2nd division, Vortices. It would stand as 

 a Carocolla of Lamarck. Whoi'ls six, exclusive of the apex. 



5. Helix climacterica. Testa subdepressa, subtus tumida; spira 

 sub-conoidea, gradata ; anfractibus omnibus angulatis, supra planatis, 

 argute plicatis ; apice obtuso. Periphaeria angulata. Peristomate 

 acuto, non reflexo. Umbilico nullo. Diam. 0.75 poll. 



This species resembles H. barbata of Cephalonia in its general 

 habit and in the peculiar form of its spire, which rises like a flight of 

 steps ; but the apex, though obtuse, is more exserted, and is desti- 

 tute of the flattening observable in the Cephalonian species. Whorls 

 eight, exclusive of the apex. It belongs to Helicigona of De Ferussac, 

 and to its first groupe, which is destitute of an umbilicus. 



6. Helix Serrula. Testa subdepressa, sub-conoidea subtus convexa ; 

 apice acuto ; anfractibus supra confertissime radiatim plicatis, margi- 

 natis, marginibus elevatis ; ultimo anfractu infra lseviore, periphaeria 

 marginata, serrata. Umbilico profundo, mediocri ; peristomate acuto. 

 Diam. 0.55 poll. 



Whorls seven, exclusive of the apex. This is also a Helicigona, 

 2nd groupe. It is allied to a new unnamed species which I have from 

 Malta, but has a smaller umbilicus in proportion, and a more acute 

 spire. It is also larger. 



7. Helix tapeina. Testa sub-conoidea, supra convexa, subtus 

 tumida ; epidermide minutissime corrugata ; periphaeria angulata, 

 peristomate non continuo, subreflexo. Umbilico mediocri, profundo ; 

 omnes anfractus exhibente. Diam. 0.6 poll. 



Whorls seven, exclusive of the apex. It is allied to Carocolla 

 Lapicida, but differs in sculpture, in its discontinuous peristome, less 

 angular periphery, and more conoid spire. The aperture is also more 

 open. It belongs to the 2nd groupe of Helicigona of De Ferussac, 

 and to the genus Carocolla of Lamarck. 



8. Helix delibratus. Testa depresso-plana, subtus tumida ; epi- 

 dermide cornea decidua ; anfractibus transverse striatis ; apertura 

 transverse rotundato-ovata ; peritremate vix continuo, reflexo; umbilico 

 lato, anfractus plerosque exhibente, Diam. 0.9 poll. 



Whorls four. Of the same type as the European species H. cornea, 

 from which it differs in colouring and in tbe form of its spire, whiqh 

 resembles that of H. deplana of Croatia ; but from this species it 

 differs in the form of the mouth, and in the markings, as well as in its 

 more open umbilicus. From Helix granulata (mihi) of the Western 

 Provinces, it differs in the more transverse mouth, more flattened spire, 

 and wider umbilicus, in its plainer colouring and greater size, and in 

 the want of that minute shagreened appearance, under the lens, which
