angle at the upper part of the whorls where they become flat to 

 the suture. The umbilicus is margined with a conspicuous 

 beading of rounded granules. It is sufficiently related to its 

 Australian congeners to entitle it to the name of being Aus- 

 tralian or allied to our living fauna, but I cannot find anything 

 like it amongst the fossils of Europe or America.

This species is not uncommon at Muddy Creek. It is very 

 close to Liotia Australis ; and I question very much if it be 

 distinct from the species described by me as L. lamellosa,* 

 from the Table Cape beds. The latter, however, was only half 

 the size of this. Its general character is decidedly near to many 

 Australian forms. One peculiarity in it is the two varices round 

 the aperture. They are close, rather thin, and sculptured like 

 the whorls. 



I append Prof. Tate's note on this fossil He says, " This 

 may be your species of Table Cape, but it is not identical with 

 the living one of the name. The differences observable between 

 the now living examples and the fossils are the subquadrate outer 

 whorl, more depressed form and more numerous transverse 

 costse of the living. More than twenty fossil examples agree in 

 the rounded outer whorl and more open tessellated ornament. 

 As the species was instituted for the fossil form the recent allied 

 should be renamed." This suggestion I think I would pro- 

 visionally, at least, adopt and name the recent species Liotia 

 subquadrata. The species was inadvertently omitted from my 

 " Census of Tasmanian shells."
