straight medially, thence slightly expanding to the hardly con- 

 tracted broad, short, open canal. Columella nearly straiglit, with 

 four oblique slender plaits, the anteiior one of which is the 

 smallest. 



Dbyipusions. — Length, 46-5 ; breadth, 14 ; aperture, 25-5. 



Locality. — Lower beds at Muddy Creek. 



This species is closely related to V. pseiLdo-lirafa, but is dis- 

 tinguished by the spiral sculpture and the reduction of the costie 

 to tubercles.

Reference. — Gastropods, part I., plate xiii., fig. 7. 



Has the general form of V. cathechrdis, but all the whorls, six, 

 excejDt the pullus, are medially sub-angulated and spinosely 

 tuberculated on the keel ; the apex is sub-acute of one and a half 

 small, narrow-rounded whorls. The sculpture consists of tiney 

 spiral, wavy stride, which are somewhat obsolete on the middle of 

 the last whorl. Body- whorl more attenuated towards the base, 

 wdiich is bent and reverted. Columella with four sub-equal, equi- 

 distant, rather slender plaits. 



Dimensions. — Length, 51 ; breadth, 16; length of aperture, 28,

 (1880) ; id. Geology Tasmania, t. 30, figs 3— 3a. 



Shell broadly lanceolate, fusiform, with a moderate high acute 

 spire, ending in a small sharp pullus of two smooth turns. Whorls 

 six, with regular sigmoid ribs wdiich become somewhat obsolete' 

 towards the posterior suture, and towards the base of the body- 

 whorl, but are raised into distinctly angled tubercles on the 

 anterior-third of the whorl (12 on the last Avhorl) ; outer lip 

 simple ; columella nearly straight, with four stout oblique plaits. 



Dimensions. — Length, 70 ; breadth, 20 ; length of aperture, 40. 



Locality. — Table Cape {R. 21. Johnston /). 



This species closely resembles V. IvreusJerrp, Angas, of South 

 Australian waters, but the spire is more acute. 



28. Voluta tabulata, Tate. 



Reference. — Gastropods, Part I., plate xiii., fig. 3. 



Shell fusiform, with a rather short spire, ending in a moderately 

 large pullus of two and a half whorls, the last half whorl costu- 

 late. 



Whorls three and a half to four, excluding pullus, angulated 

 ante-medially, costated in front of the keel, and sharply tuber-
