PSEUDOLIOTIA MICANS, A. Aclams, VAR. SIMPLICIOR, Tate, 1898. 



Cyclostrema micans is the type of a new genus, rseudoliotia 

 which I propose to establish. Ttie present variety dififers by the 

 acute axial costee, which do not form nodulations on the spiral 

 carinse. In consequence, the periphery appears markedly trun- 

 cate with a deep concave sulcus between the two peripheral keels. 

 Nevertheless, the normal forms show some variation in the den- 

 sity of the nodulation and by decrescence of that character would 

 graduate into the variety here described. Unfortunately only 

 one example (an adult) was found, and that of 2 mm. diameter. 

 This size is much smaller than usual, which ranges up to 4 mm., 

 yet it is not smaller than a micromorph, which occurs abundantly 

 at Port Western, Victoria, or than Liotia speciosa, Angas, which 

 is conspecific.
