64 NEW SPECIES OF TASMANIAN MOLLUSCA, ETC. 



suture impressed, apical whorls much flattened. Aperture 

 pyriform ; outer lip thin and sharj>, somewhat expanded 

 anteriorly. 



Length, 2; breadth, .8 mill. 



Type, with two others, from 40 fathoms off Thouin 

 Bay, one other from off Arch Island, D'Entrecasteaux 

 Channel. 



I place this with Fisxop.v's, as it seems congeneric with 

 the species assigned to that genus by Professor Tate, a 

 location which I think requires confirmation.

LiPPISTES CONSOBRINA, Sp. nov. 



Shell small, whitish, smooth, pyramidal, timbilicate. 

 Whorls four or five, including a smooth proto-conch of 

 about two turns. The adult whorls are encircled bv rwo 

 strong keels, the upper of which is the larger, and is a 

 little above the centre of the whorl. These keels are 

 separated by a furrow of about their own width. There 

 are two additional keels on the base, the anterior of which 

 encircles the umbilicus, which is deep, but rather narrow, 

 and separated from the aperture by a strong columella 

 pillar. Aperture rounded, outer lip strongly dentated by 

 the keels. 



Length, 3; bi'eadth, 1.5 mill. 



Type, with three others, from 40 iathoms three miles 

 East of Schouten Island. 



In these proceedings for 1910, p. 309, I recorded this 

 species as L. gracilenfa, Brazier. I have since had an op- 

 portunity of examining Brazier's type, which shows that 

 the two forms are specifically distinct, (irarUcnta being 

 much larger and more attenuate in the spire. Our shell 

 comes between this and L. zofTxiru^, Hedley, which is 

 similarly sculptured, but is only half the length, and has a 

 different apex.

CePvITHIOPSIS APICICOSTA, sp. 110V. 



Shell small, elongate, or narrowly pyramidal, whitish. 

 Whorls eleven, inchuding a three-whorled proto-conch, 

 which is strongly axially ribbed. Adult whorls moderately 

 rounded, sutui'e well impressed ; sculpture, three nodulous 

 keels of about equal size and distance encircle the whorls. 

 They are separated by a deep groove, across which the 

 nodules are connected by low axial ridges. There isi a
