Tliis species may be readily distinguished by its peculiar 

 close reticulation of brown and pale yellow sharply angular 

 lines. They form very fine acute zigzag markings of equal 

 width, and extremely close together. In form it is like a 

 very small C. semiconvexa. The color is very constant, and 

 there are no cloudings or spots of any kind.

This beautiful little Erato is the only one known from Tas- 

 mania. It is highly polished and shining, and almost per- 

 fectly pellucid, with a slight milky clouding. The color, 

 however, looks darker within, almost livid, but this, I am 

 convinced, arises from the remains of the animal. There are 

 three pipits on the columella which decrease posteriorly, and. 

 the base of the columella is twisted round so as to look like 

 a fourth ; the spire is only very slightly exsert, showing 

 about 2J whorls ; the teeth on the outer lip are numerous, 

 but very faint and inconspicuous.

This beautiful little species is mainly distinguished by its 

 distinct and equal spiral grooves, which are very neatly 

 dotted with close round pits like an extremely fine chain. 

 The color is white but almost pellucid, and the shape is elon- 

 gately turbinate. The mouth is quite entire a.nd anteriorly 

 exserted.
