 Brazier to a shell dredged by tlie Kev. Mr. Atkinson, Long Bay. I have not

HiATULA viTREA. DesJiayes, Zool. Proc, 1854, p. 326. Thin, white, glassy, 

 and transparent. Said by Mr. Angas to occur in Tasmania, but I have met 

 no traces of it, so it must be very rare. Common in S. A. 



Semele decora, a. Adams, Zool. Proc, July, 1853. Orbicular, some- 

 what inflated, densely reticulated with small radiating and concentric ridges.

 a small form of Tellina decussata. 



Semele exigua. H. Adams, Zool. Proc., 1861, p. 385. Mr. Adams 

 describes as from Tasmania an oblong transverse inequilateral shell, shining, 

 thin, white, finely concentrically striate, posteriorally subangulate, with a 

 strong fold continued to the ventral margin. I have never seen the shell, 

 and it is not known to Tasmanian collectors.
