The geueral aspect of this shell is not much unlike that of C. 

 venosa, but the difFerence may be easily detected on examination ; 

 instead of being veined with fine lines of colour upon a white ground, 

 the obliąue ridges are raised upon a red ground ; besides this, the 

 upper valve is characterized by a double style of both colour and 

 sculpture, the anterior half being of a dull brick-red colour and ap- 

 pressly scaled, whilst the posterior half is similar to the under valve. 

 Mr. Broderip has figured this shell as the young C. imbricata, but it 

 is f ar removed from that species.

Hab. Cagayan, island of Mindanao, Philippines (attached to 



stones) ; Cuming. 



The under valve of the specimen here represented is more squa- 

 mate, and the scales are more erect than the upper. 



Chamą Jukesii. Cham. testd ovatd, valvis ambabus pro/use et

 Hab. Cape Upstart, North Australia (on the coral reefs at low 

 water) ; Jukes. 



I dedicate this shell with a great deal of pleasure to Mr. Jukes, 

 the zealous naturalist of H.M.S. The Fly, to whom this monograph 

 is indebted through Mr. Cuming for several interesting species. 



Chamą sarda. Cham. testd suborbiculari, valvis ambabus peculi- 

 ariter exiliter obliąue striatis, squamis brevibus asperis remotis ; 

 intus extusque vividi corallo-rubrd. 

 Hab. Hondūras (attached to coral) ; Dyson. 



Rich in colour and very characteristic in sculpture, being crossed 

 in an obliąue direction throughout \vith faint striae, and roughened 

 here and there with short scales, like the asperities of a coarse file. 



The follo\ving paper, by Dr. J. H. .fonas, containing descriptions 

 of two new Shells, was also communicated by Hugh Cuming, Esq.

The form of this shell difFers so much from all those known to 

 me, that 1 find it impossible to compare it with any of them ; its
