TESTA tubulosa, cylindraceo-angulata, primum 

 repens, tandem erecto-undata. Apertura orbi- 

 cularis, margine in lingulam spatulatam liinc 

 terminate. Operculum orbiculare, (galeiforme) 

 valvis testaceis variis superne armatum. V alvse 

 quinque ad novem, opereuli margine hinc affixae; 

 uniea mediana lineari-truncata caeteris major.

 operculum, it cannot be generally adopted, but must 

 eventually merge into Lamarcit's Vermilia ; the variable 

 appearances of whose opercula seem to us at most to 

 present specific and not generic distinctions. Nevertheless, 

 as without a knowledge of the subject, no conchologist 

 will be enabled to determine for himself the propriety of 

 retaining or rejecting the Genus in question, we are 

 glad of an opportunity of giving a representation of it, 

 inasmuch as we believe none has been given in any work 

 before us, if, indeed, we excv^pt that in " Bowdich's Ele- 

 ments of Conchology,'^ part 2nd, where the operculum is 

 entirely omitted. But we have a more cogent reason still 

 for giving this Genus a place in our work, it is this, that 

 Lamarck, who appears to have been perfectly aware of 

 its near affinity to Vermilia, has only separated these two 

 genera from a persuasion that such peculiarities in the 

 operculum and aperture, joined to the very peculiar
