Art. XXXIX. — List of Marine Mollusea from Lyall Bay, near 



Wellington, New Zealand. 



By Tom Iredale and M. K. Mestayer. 



[Bead before the Philosophical Institute of Canterbury llth December, 190".] 



The authorship of this list requires explanation. All the larger 

 shells were collected by Miss Mestayer, whilst the minute forms 

 were sorted and identified by Tom Iredale from shell-sand and 

 seaweed-washings collected by Miss Mestayer. Therefore, whilst 

 all the credit for this list is due to Miss Mestayer, all the blame 

 must be undertaken by Tom Iredale, who holds himself respon- 

 sible for all identifications and errors of nomenclature. 



This paper has been prepared with a view to furthering 

 our knowledge of the geographical distribution of the marine 

 Mollusea of New Zealand, which at the present time is very im- 

 perfect. This is chiefly due to the extent of coast-line and the 

 scarcity of workers. 



We have no new records of large shells, as the locality under 

 notice has probably been collected more thoroughly than any 

 other in New Zealand, save, perhaps, some Auckland collecting- 

 ground. The shell-sand, however, is very rich, and has pro- 

 vided a number of new species, though the most interesting find 

 is not a new shell : we refer to the occurrence of Limacina 

 australis, Eydoux and Souleyet, details of which are given in 

 another place. Further diligent search in shell-sand will doubt- 

 less add many species to this record.
