This is certaiidy not the young of Cassis ylauca, as 

 stated by M. Kiener ; whether it should be regarded as a 

 variety of that species may remain a matter of opinion, 

 but I believe it to be distinct. Though not of very common 

 oceui'rence it is not rare, and there appears to be no nearer 

 approximation between the species than is represented by 

 the accompanying figures. The C. coronulata is of a more 

 oblong-oval form and perfectly smooth, without the least 

 intbcation of those ciu-ious flattened indentations which 

 characterize the C. glauca ; the tessellated painting is 

 peculiar and constant, and the spinous processes at the 

 base of the lip are but three in number and very obscui-e.

TuE PLoi'GiiED Helmet. Shell ovate, spire somewhat 

 acuminated, sharp at the apex, whorls one-varicose, 

 smooth, transversely regidarly sharply grooved, slant- 

 ing at the upper part, spii-ally ribbed, ribs very 

 closely beaded; columeUa broadly concavely ex- 

 panded, profusely and very finely plicately wrinkled, 

 outer li[) strongly dentately ridged ; ivory white, 

 tessellated with distant pale fulvous square spots. 



Uab. ? 



A new and very distinct species allied in form to tlie 

 C. glauca and coronulata. Its chief pecuUarities consist 

 in the surface being encircled with narrow equi-distant 

 grooves, and in the S[nre being strongly beaded. The 

 columella is very widely expanded, and profusely sculp- 

 tured with fine divaricating wrinkles.
