T. coronata , Tate,* * * § there is a broad and deep channel at the suture. 
All the members of the Struthiolariidse have, in the position of 
the anterior furrow of Zemira , some conspicuous mark, either a 
ridge, a line of tubercles, a depression, or an angle. All have a 
projection answering to the point on the lip of Zemira , which is 
more or less developed, and attains a maximum in the case of 
Struthiolaria calcar , Hutton, f The feature which I would chiefly 
emphasise as pointing to the Struthiolariidee is the broadened and 
incurved anterior termination of the columella. The southern 
habitat of Zemira agrees better with the distribution of the 
Struthiolariidse than with a group so typically northern as 
Buccinidee. On the other hand I must admit that though the 
operculum of Zemira , as figured by Kobelt,; does not well agree 
with that of Eburna y figured by Adams, § yet it does not answer 
to those of Struthiolaria figured by Gray,|| or Smith. H 
Whatever may be the ultimate destination of Zemira , there 
can be no question but that Tate's genus j Eburnopsis** must 
accompany it there. According to figures, Pseudoliva zebrina , 
A. Adams, tf bears a marked resemblance to these forms ; but 
having no personal acquaintance with the species, I forbear to 
comment further on it. 
These notes on the shell characters were put together several 
years ago. I had hoped that an examination of the animal 
might prove or disprove the opinion now expressed, but, unfor- 
tunately, I have been unable to procure Zemira australis in the 
flesh. From the distribution of dead shells, I conclude that the 
species lives in depths of a few fathoms on sandy ground. So far 
as known to me, the range of the species is from Sydney north- 
wards to the Queensland border. 
Most authors who have dealt with Zemira have coupled 
it with Eburna , a reference as unnatural as that of Lamarck, 
who called it Cancellaria. Fisher’s opinion that it is related 
to Macron is more plausible. It is here suggested that to 
include it in the Struthiolariidse would harmonise better with 
the geographical distribution and the shell characters. Informa- 
tion obtainable from the unknown animal may, however, place it 
in a group of equal value not yet differentiated.
