120 RECORDS OF THE AUSTRALIAN MtTSEUM. 



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 Struthiolariidje is the broadened and 

 incurved anterior termination of the columella. The southern 

 habitat of Zemira agrees better with the distribution of the 

 Struthiolariidie than with a group so typically northern as 

 Buccinidse. On the other hand I must admit that though the 

 operculum of Zemira, as figured by Kobelt, | does not well agree 

 with that of Ebicrna, figured by Adams.v^ 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 SJburnopsis** must 

 accompany it there. According to figvires, Pseudoliva zehrina, 

 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 Struthiolariidie 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 diSerentiated.
