Hab. Island of Mindoro, Philippines (attached to coral) ; Cuming. 



The sculpture of this species somewhat approaches that of the 



C. spinosa ; it is of a more minute and delicate character and easily 



distinguished on comparison. 



Chamą variegata. Cham. testd oblongo-ovatd, circiter trigond,

 Hab. Hondūras; Dyson. 



The colouring of this shell has a very pretty efFect, the obliąue 

 ridges and other external sculpture being white upon a coral or 

 orange-red ground. 



Chamą cistula. Cham. testd orbiculari, postici profunde sinuatd, 

 ■V valvis ambabus peculiariter rude lamellatd et sąuamatd, squamis 



ad margines subproductis, appressis, valvarum marginibus leevibus ; 

 albidd, roseo-fuscescente varid, intus albd. 

 Hab. Hondūras ; Dyson. 



The upper valve of this shell is rather more convex than usual ; 

 the sculpture peculiarly rudely developed.

valvarum marginibus Icevibus ; aurantio rufoąue varid, liris posticis 



albis, intus albd. 



Hab. Hondūras (attached to coral) ; Dyson. 



A striking species, though of rude grovvth ; it is doubly sinuated 

 on the posterior side, having round orange protuberances along the 

 summit, whilst the channeled interstices have a striped appearance, 

 from their being crossed by white ridges on a blood-red ground. 



Chamą lingua-felis. Cham. testd orbiculari, supra depressiusculd, 

 valvis ambabus prcecipue inferiore minute retuse sguamatis, supe-

 bus leevibus ; nived, rosaceo hic illic tinctd. 

 Hab. Island of Guimaras, Philippines (attached to stones) ; Cu- 

 ming. 



An extremely delicate and characteristic species, in which the 

 upper valve is very finely laminated, vi'hilst the ground sculpture of 

 both that and the lovver valves is of a curious roughened character, 

 somewhat similar to the Telline scobinata and Ungua-felis.
