Ohs. Tills bears a great general resemblance to 

 Cassis glauca, Lam. and might easily be mijstaken for 

 that species : the following are the particular cha- 

 racters by which it may be distinguished : a more 

 elongated general form, its light brown markings 

 upon a lightish ground colour, and its wanting the 

 sharp teeth at the basal margin of the outer lip, as 

 well as a projecting appendage at the corresponding- 

 base of the inner lip,

06s. This shell cannot properly be arranged with 

 the Cassides: in our opinion it forms a good genus, 

 to which also Doliiim Pomum should be referred. In 

 the present Catalogue we have transferred the latter 

 to the genus Cassis, in order that the two species 

 might be brought close to each other. In this re- 

 spect we have followed Swainson, notwithstanding 

 our own conviction that they approach nearer in 

 natural affinity to Dolium. 



1826. CASSIS COARCtATA. 



C. testil cylindraceo-oblonga, laeviuseula, albidi, cas- 

 tanco-variegata ct interrupte fasciata, spira brevi, 

 subacuminati; dorso seriebus quatuor tubcrculo- 

 rum subobsoletorum ; apertui'a elongata, superne 

 coai-ctatA ; labio cxterno marginc acutiusculo, in- 

 tus dcntato ; columella plicatfi ; long. 2/^ lat. 1 /-^

Obs. Certainly not a common species, though wc 



liave met Avith it several times. We believe it to be 



a New Zealand shell.
