Locality. — -Eocene, Table Cape, Tasmania. Also from the eocene 

 ferruginous beds of Keilor (T. S. Hart), and Royal Park (Rev. 

 Mr. Ramage), and from the eocene limestones (upper beds) of 

 Moorabool Valley, at Maude. 



Observations. — I have taken the liberty of describing and 

 renaming this species owing to the Aery unsatisfactory and 

 unrecognisable condition in which I find it. In the first place 

 Mr. R. M. Johnston recorded with a doubt the occurrence of 

 the living New Zealand species, Astraliuiu {Imperator) iwperiale, 

 Chemnitz. This record in all probability x'efers to the present 

 species, which, however, is undoubtedly distinct from its living 

 analogue. When next we meet with an Iviperator in Mr. John- 

 ston's Geology of Tasmania, we find two figures on plate xxix. to 

 which the name of /. hudsoniana., R. M. Johnston, is attached in 

 the explanation of the plate ; but upon looking up the list of 

 Table Cape species given by the same author in the same work, 

 the only Iviperator there recorded is /. tasmaiiica, R. M. John- 

 ston, MS. As I have been unable to find any description which 

 goes with either of these names, and as the figures given of /. 

 Jmdsoniana do not render its identification anything but a nmtter 

 of extreme doubt, I have concluded to desci'ibe the shell and 

 dedicate the species to Mr. R. M. Johnston.

Shell somewhat thick in the adult form, conical, nacreous 

 internally, with a well-elevated spire ; suture not well defined, 

 being most distinct between the body and penultimate whorls. 

 Base very slightly convexly rounded, thus giving rise to a some- 

 what abrupt convexity at the periphery of the body-whorl, most 

 noticeable immediately above the mouth ; the base as it ap-
