columella slightly twisted and white.* There is only a very 

 faint umbilicus. The shell is finely striate lengthwise. These 

 striae widen on the edge of the sutures where they form little 

 irregular folds. The general color is a greenish yellow, streaked 

 with brown encircled on the last two whorls of the spire with a 

 little chestnut brown band, bordered by yellow lines at the two 

 sides ; a wide brown band proceeds from the summit of the 

 peristome, turns round the columella, and is prolonged anteriorly 

 on to the last whorl. The summit of the spire is brownish. In 

 its young state the shell is globular, with a rounded aperture, in 

 which the brown bands are perceptible. The animal has long 

 posterior tentacles, while the anterior ones are of medium length. 

 The mouth is in the midst of a muzzle of two lobes. All the 

 upper part of the body as well as the sides are brown or almost 

 black, shot with reddish. The foot is yellow underneath and 

 when fully extended hardly reaches behind the shell. This 

 Helix inhabits the Island of Van Dieman. It is not very 

 common. We found it hidden under stones on the hills around 

 Hobart Town. Some individuals were provided with an epi- 

 phragma.t Length 11 lines, thickness 5.

 Shell oblong oval thick and solid with a somewhat elongated 

 spire, convex, obtuse at the summit, five flattened whorls joined 

 by a suture bordered by a slight plaited margin. Last whorl 

 rather large, subcylindrical convex at the base and imperforate. 

 The aperture is of medium size, oval, dilated at the base, attenuated 



* All these detail show that the species would not enter into Ehrenberg's genus Buliminics.

 little known to English readers. It has become very scarce.
