Fossil Fauna, Table Cape Beds, Tasmania. 101 



vening furrows, on the spire-whorls, becoming obsolete on the 

 body-whorl, also transverse lines of growth and line parallel 

 striations, which become more distinct and somewhat sigmoid on 

 the body-whorl. 



Dimensions. — Length, 133 mm. ; breadth, 67 mm. ; length of 

 aperture, 92 mm. ; breadth of aperture, 31 mm. 



Locality. — Eocene beds of Table Cape, Tasmania. 



Observations.— ^\\Ss, very fine volute I have named as a com- 

 pliment to Mr. E. D. Atkinson, whose careful and extensive 

 collecting from the Table Cape beds has so enriched our knowledge 

 of this particularly interesting fauna. This new species evidently 

 belongs to that group of our eocene volutes typitied by V. 

 haftnnjordi, McCoy, but as it does not show any very close 

 relationship to any of our hitherto described species, and has so 

 many characteristic features of its own, any differential remarks 

 seem to be at present unnecessary. There is, however, a very 

 closely related if not identical form fi'om the eocene beds of 

 Birregurra, Victoria, procured by Mr. T. S. Hall from material 

 from that locality ; but at present I refrain from expressing an 

 absolute opinion, in the hope that I may be able to obtain more 

 specimens for closer examination. 



37. Voluta halli, sp, nov. Plate XL, tigs. 1, 2 and 3. 



Shell large, elongate-fusiform, with a small manimilate apex 

 and a long slender spire, terminating in a large, elongate body- 

 whorl, usually with a long and comparatively broad aperture 

 ending in a short, broad canal. Well preserved examples still 

 retaining a high polish. 



Apical angle about forty degrees. Embryo maramillate, three 

 to four millimetres in diameter, consisting of about one-and-a-half 

 obliquely enrolled, smooth whorls, the axis of enrolment making 

 an angle with the axis of the spire of about one hundred and 

 forty degrees or slightly upwards. The apex of the embryo is 

 prominently exsert and somewhat eccentric, the exsert portion 

 being very sharply pointed and inclined towards the centre. 

 The spire in the adult form consists of about eight gradually 

 increasing whorls ; the earlier spire-whorls are usually flat, 

 occasionally very faintly convex, between the well-defined sutures,
