Cassis tuegida. Cass, testa ovatd, tenuieuld, ventricosd, 

 spird suhacmnittatd, anfradUnis evaricosis, leevibus, 

 turgidis, superne roliindatis ; columelld valde contortd, 

 ba-si mi'tpllcutd, lahro muluiiie dentato-spinoso ; laded, 

 palUde castaneo hiKjitiidinaliter flammatd, lahro intense 

 castaneo maadato. 



The swollen Helmet. Shell ovate, rather thin, vcntri- 

 cose, spire somewhat acuminated, whorls destitute of 

 varices, smooth, swollen, rounded at the upper part ; 

 columella much twisted, one-plaited at the base, lip 

 deutately spinous throughout ; cream-coloured, longi- 

 tudinally flamed with pale chesnut, lip spotted with 

 very dark chesnut. 



Hab. Boljoon, Island of Zebu, Philippiues (on sand 

 banks) ; Cuming. 

 A fine species belonging to the same gi'oup as C. aclta- 



tina, vibex, and torquata ; the whorls are distinguished for 



theii- swollen rotundity, and the columella is remarkably 



twisted. The lip is dentately spinous throughout, 

 not seen any nodided variety of this species.

Cassis undata. Cass, testa ovatd, giljbosiusculd, spird 

 aciimmatd, apice aciitd; avfractibus miivancosls,

 albicante,fuhesce)de-fuseo longitmlinaUler striata. 



The waved Helmet. Shell ovate, rather gibbous, spire 

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

 smooth, conspicuously grooved at the base, a little 

 depressed and striated round the upper part., gi'anu- 

 lously decussated towards the apex; columeDa pli- 

 cated and interniptedly wrinkled, tubercidated in the 

 middle, lip very strongly dentately ridged, ridges 

 elongated ; bluish-white, longitudinally streaked with 

 fulvous brown.

 Hab. Phihppine Islands ; Cuming. 



Although the patterns of this species and the C. areola 

 are united in the C. dectmata, they are not varieties of the 

 same as assiuned by Bruguiere and Kiener. The C. areola 

 is a narrower and more gibbous shell than the C. mulata, 

 which is eminently distinguished from the former by the 

 strong linear grooves around the base. The dentate ridges 

 on the outer lip are longer and more strongly developed.

The plicated HelKet. Shell somewhat elongately 

 ovate, pecidiarly compressed, spire somewhat acu- 

 minated, shai-p at the apes ; whorls one-varicose, 

 transversely finely linearly grooved, eoncavely slanting 

 at the upper part, nodidously crenated at the margin, 

 encii'cled by two finely beaded ridges beneath, con- 

 spicuously prickly noduled at the angle, nodides 

 descending in prominent slightly curved plaits : 

 columella widely expanded, pHcately wrinkled, 

 wrinkles short, lip sharply dentately ridged, obso
