irregular longitudinal fold-like stride, which are, some- 

 times, partially confluent, or connected by short branches, 

 clothed with a closely adherent, and more or less shining 

 epidermis of a yellowish olive colour. Spire very short ; 

 body extremely large ; apex blunt. Whorls four mode- 

 rately rounded, rapidly enlarging ; the last not distinctly 

 deflected. Aperture higher than broad, obovate, equal 

 in width to two-thirds the total diameter of the shell, 

 rather suddenly contracted above by the arcuation of 

 the penult whorl. Peristome thin, simple, not reflected, 

 slightly edged with white, much arcuated below, its di- 

 lation upon the produced pillar very slight ; a rather 

 obscure shelly coating connecting the two lips in the 

 adult. 



The animal is very large for the shell ; its colour is 

 brownish grey with dusky tentacula. 



A large foreign example measured an inch and an 

 eighth in length, and an inch and a fifth in breadth. It 

 finds a place in the "British Fauna" on account of a 

 specimen found in Guernsey, in 1839, by Professor E. 

 Forbes, and deposited in the British Museum. It is 

 common in the south of France.

Obliquely subglobose, beneath the epidermis pale fawn- 

 coloured, with four (usually interrupted) chocolate-brown bands.
