 The porcupine Cockle. Shell somewhal squarely cor- 

 date, posteriorly concavely angulated, radiately ribbed, 

 ribs about two and thirty in number, narrow, com- 

 pressed, the posterior elegantlj ornamented with small 

 short scales, the rest with erect scale-like spines, a 

 little inflected towards theumbones; interstices be-

Variety (1. 

 Testa extus omnino nivea. 

 Shell exteriorly entirely white. 

 Rah. Island of Corrigidor, Philippines (found in coarse 

 sand at the depth of about seven fathoms); Cuming. 

 The exquisite delicacy and beautj of this shell is re- 

 markable; each rib is surmounted with a close-set row of 

 slender scale-like spines, and the interstices are minutely 

 cancellated ; they are moreover tinged with pink, and down 

 each side of the ribs is a bright scarlet line. 



The accompanying figure is lithographed by Mr. G. E. 

 Sowerby, Jun., from a very clever drawing of the specimen 

 in Mr. Cuming's collection executed b\ his sister, a lady of 

 eminent talent in natural history painting. 



There is another very beautiful small specimen of the 

 Cardium hystrix in the collection of Miss Saul; and Mr. 

 Cuming is also in posse: 



of two of the while \ariet\ .

 The pretty Cockle. Shell orbicular, thin, somewhat 

 depressed, nearly equilateral, radiatelj closely striated, 

 stria' solid, raised, regular, the posterior striae covered 

 with very minute scales ; while, stria' some few while. 

 most of them bright scarlet; interior yellowish, two

 Hab. Australia. 



This very pretty species cannot surely be the \oung of 

 the Cardium striatulum; it is of a different form, being 

 truly orbicular, and oilers no indication of the wrinkled 

 stria' with which that species i- so peculiarly cancellated.
