400 LIST OF LAMP SHELLS FOUND IX PORT JACKSON, ETC. 



4. Terebratuh sanguined, Cliera. and Davidson. Lifou, 



Tuojdlty Islands. 



5. Terelratulina cancellata, Koch., Sowerby, and Gray. I take 



it to be that species from the description by Mr. Sowerb}^ 

 in Thes. Conch. The British Museum Catalogue, by 

 Dr. J. E. Gray, gives but a brief desertion. 



I herewith give Mr. Davidson's notes and remarks received 

 by last mail on the above mentioned five species. 



1. Magasella Cumixgi, Davidson, (my No. 1). 



"During many years after I had described and figured this 

 remarkable species, and indeed until fourteen months ago, no one 

 in Europe knew exactly where this shell lived. Mr. Cuming had 

 a specimen or two, one of which I described, and ho told me he 

 had been told it came from New Zealand seas, but the New 

 Zealand Naturalists with whom I corresponded told me they had 

 never found it in their waters. 



It was only some fourteen months ago that while in Mr. 

 Sowerby's shop I saw several specimens of the Magasella (it is not 

 a Mag as, the loop and septum are those of Dall. Magasella) and 

 he told me he had received them from Port Jackson Heads ; 

 shortly after I found among the Challenger dredgings two separate 

 valves of the same shell, also labelled Port Jackson Heads, and 

 some months ago Mr. Tenison-Woods, sent me sev eral specimens 

 which he informed me he had procured from Sydney Harbour, 

 and that when the shell was alive it had a rose colour tinge, but 

 that it was difficult to procure living specimens, dead ones being 

 common enough. I am delighted to procure the full information 

 you kindly communicate on this species. 



"I believe your No. 1 and 2. belong to the same species, or 2 

 is a variety of No. 1 . It is a beautiful shell and I cannot help 

 thinking that Peeves' Boucliardi a fibula, is only a large variety of 

 Magasella Camingii, I also think Magasella Cumingii may occur 

 in the Tertiary deposits of Australia.
