 depress a Flem. {=pIanorbis Fabr.), Natica helicoides Johnst. {^= 

 islandica Gmel.), Murex cofaHinus Scacchi {=adailat7(s Lam.), 

 etc. Odostomia as given in Jeffreys, on a similar principle, I have 

 divided into Odostomia Chemnitzia and Eulimella. lanthina 

 exigiia Lam., which does not appear on Jeffreys' list, I have 

 inserted. Nassa nitida Jeffr. I have relegated to what it doubtless 

 is, a var. of N. reticulata L. Hydrobia ulvcz Penn. appears with 

 the other Hydrobix^ as a fresh water shell. Assiminea, however, 

 I have left as marine. 



The remarks as to localities, which were made on the Con- 

 chifera, apply here with equal force, except that there are a rather 

 larger proportion here to which I have had to append "no loc." 



Only one representative of the Pteropoda can fairly be said 

 to inhabit the British seas. This is well represented, both in type 

 and varieties, in the collection. 



SOLENOCONCHIA. 



Siphonodentalium lofotense Sars. No locality. 



Jeffreys' handwriting. Three specimens. 

 Cadulus subfusiformis Sars. Zetland. 



Three specimens. 

 Dentalium entalis L. Scotland. 



Two or three of the larger specimens are considerably 

 eroded at the posterior end. 

 D. entalis L, Galway Bay. 



This is not a satisfactory card. It contains eleven 

 specimens. Of these, five belong to Z>. entalis and six 

 to Z>. Tarentinum. The pink tip, and more particularly 

 the strongly striated, dull, not glossy surface, settle the 

 difference. 

 D. tarentinum Lam. Southampton, &c.
