PETTERD : WOODS "CENSUS OF TASMANIAN SHELLS." 353 



CRITICAL REMARKS ON THE REV. J. E. TENISON 

 WOODS' "CENSUS OF TASMANIAN SHELLS." 

 By W, F. PETTERD. 

 The following specimens are synonymous : — 



1. Assiminea the same as Rissoa sietmx. ' 



2. Trophon Srazieri the same as Siphonalia castanea. 



The only feature of difference is that 6". castanea are 

 beach-worn specimens. 



3. Siphonalia pulchra the same as Pleurotoma philomence. 



The only difference between these shells is that Siphon 

 alia pulcJira is a young shell with the lip undeveloped. 



4. Riima globosa the same as Ruma muhilicata, but some- 



what larger than the typical forms. 



5. Con us iVIacleayana is the same as Conus rutila. 



There can be but little doubt that Woods' species C. 

 Macleayana is but a large specimen of C. rutila, vide 

 description. 



6. Phasianeiia delicatula. 



This is but the young immature P. trito?iis. I have 

 collected specimens showing every gradation of growth. 



7. Turbo Simsoni. 



Undoubtedly, but the young of T. undnlattis. Speci- 

 areto be found as often with as without the carination, which 

 is lost on the more mature growth of the shell. 



8. Carinidea Tasmanica. 



As the Rev. Mr. Woods supposes, but the young of C. 

 aurea. I have a series illustrating the stages of growth from 

 the. fry to the fully developed C. atifea, collected on various 

 parts of the coast. It is somewhat abundant in certain 

 localities on the South coast and also at Tamar Heads, on 

 the North coast, at low water on the rocks and large stones.
