Circe okbica.. Circ. itdii orbicularis tenticulari, versus 

 nmhones subtriangulari, lacted, purpiireo-nigro trans- 

 versim umlulatd, concentrice coiifertim plicato-Uratd, 

 ad uiiihoiies nitide dicaricatim plicatd. 



The ciiiCULAK Circe. Shell orbicular, lens-shaped, 

 slightly triangular towards the umboes, cream-colour, 

 transversely wavcil with purple-black, concentrically 

 closely plicately ridged, neatly divaricately plaited at

Circe tumetacta. Circ. testd snborbicidari-ovatd, pos- 

 tice decUvi-lohatd, medio tumidiusculd, fulvesceide- 

 albd, nigricante-castaneo acute lineari-undatd, concen- 

 trice rude plicato-Uratd, postice lavigatd, ad mnbones 

 divaricatiiii plicatd. 



The swollen Circe. Shell suborbicularly ovate, pos- 

 teriorly slopingly lobed, rather swollen in the middle,

 30. 



Uab. ? 



Diifei-ing from the preceding species in being slopingly 

 lobed on the posterior side, whUe the concentric sculpture 

 is more rude and irregular. 



Species 10. (Fig. a, b, Mus. Cuming.) 



ClECE CKOCEA. Circ. testd oblique suborbicidari, mine 

 compressd, nunc tumidiusculd, fidoescente-lacted, pur- 

 pnrascente pallide iinctd, ad uii/boues purpiirascente- 

 ferriigineo biradiutd, exUiter concentrice striata, ad 

 mnbones dicaricatim plicato-rugatd, intus croced. 



The saffron Circe. Shell obliquely suborbicidar, 

 sometimes compressed, sometimes rather swollen, 

 fidvous cream-colour, faintly tinged with purjjle, 

 two-rayed with purple-rust at the umboes, finely 

 concentrically striated, divaricately plicately wrinkled

Gray, Cat. Cyth. Anal. vol. viii. p. 307. 

 Cijtherea crocea, Hanlcy. 



Hab. Red Sea. 



Mostly distingiushed by two purple-rust rays at the

 coloiu'. 



Species 11. (Mus. Cuming.) 



Circe sugillata. Circ. testd circulari-ovatd, postice 

 subproductd, Uvido-albicante, castaneo-brunneo copiose

The bruised Circe. Shell cu-cularly ovate, slightly 

 prodviced posteriorly, livid-white, copiously radiately 

 stained with chestnut-brown, concentrically rudely 

 i-idged, faintly divaricately plicated at the umboes.. 



Hab. ? 



This richly-slained chestnut-brown shell approaches C. 



trigona, but it has not the triangular form characteristic 



of that species. 



Species 13. (Mus. Cuming.) 



Circe tkigona. Circ. testd orbiculari, versus umbones 

 conspicue trigona, jjlano-compressd, fulvescente-albd, 

 concentrice covfertim rude liratd, ad umbones divari- 

 catim corrugato-plicatd. 



The triangular Circe. Shell orbicular, conspicuously 

 triangled towards the umboes, flatly compressed, 

 fulvous-white, concentrically closely rudely ridged, 

 divaricately corrugatcly plicated at the umboes. 



Hab. ■ ? 



Distinguished by a flatly compressed triangular growth, 

 though still rudely concentrically ridged throughout.
