34 Mr. J. C. Melvill and Mr. Abercrombie on 



Fam. Vermetid^. 



Vermetus (Adams). 

 V. sp. One species uncertain, found amongst shingle. 



Fam. TURRITELLID^. 



TURRITELLA (Lam.). 



T. i^Zaria) duplicata (Linn.). 



Very common on all the shores. It may be that T. 

 cerea (Reeve), bacilliini (Kiene), also occurs, but as live full- 

 grown specimens have not been found, it is a little uncertain.

LiTORINA (Ferussae). 



L. (Melaraphe) intermedia (Phil.). 

 Young specimens only. 

 L. ventricosa (Phil.). 



Tectarius (Val.). 



T. Malaccamis (Phil.). 



This last is very abundant, and lives high on the sun- 

 heated rocks above the reach of all, excepting spray, or the 

 highest spring tides. L. ventricosa is also very common, 

 more to the south, and lives in similar positions.
