(Plate IV. Fig. 12), they consist of closely-set zigzag lines 

 somewhat similar in character to those of the living V. undulata. 

 They are preserved in conseL^uence of those portions of the shell 

 where they are found being more durable than the remainder of 

 the surface ; the markings are slightly in relief. 



This species is assigned to the subgenus Aulica because the 

 protoconch is identical with that of the other Australian forms 

 here included therein, and agrees very closely with that of the 

 type species. The general shape of the shell is more suggestive 

 of Scaphella, however. It is minus tubercles, or spines, and 

 lacks the solidity of V. aulica. In some respects it resembles 

 V. bednalli. Brazier, living in North Australian seas. 



The writer has not seen an authenticated specimen of V. lirata 

 as described (but not well figured) by Mr. E. M. Johnston ; but 

 accepts Professor Tate's interpretation of the species. It may 

 be pointed out, however, that Mr. Johnston describes the 

 "puUus" of his species as having only one and a half turns, 

 whilst the species as here accepted possesses three and a half. 

 In all other respects the Muddy Creek examples appear to corre- 

 spond with his description.
