CYPR^A.— Plate VII. 



This is another species of Cowry which our national col- 

 lection can alone boast of possessing. The dorsal sniface, 

 of which I have given a more characteristic view than has 

 yet been published, is of a yellowish reddish-brown, 

 sprinkled with rather large round white spots, clouded, 

 two and two, one refracting upon the other, like floating 

 particles of oil. The base is thickly crossed with fine stria- 

 like scratches, and the teeth are developed with remark- 

 able intensity, — an exaggeration, as it were, of those of the 

 Cypma mlcidentata. The posterior margin of the shell 

 exhibits on the right side a number of wart-like protube- 

 rances ; and there is a pale concentric mark over each ex- 

 tremity.

The mouse Cowky. Shell oval, sides rather gibbous, base 

 rather flatly depressed, aperture a little sinuous, teeth 

 very short, the columellar teeth more or less obsolete, 

 especially the middle, the right posterior extremity 

 obsolete ; back sometimes fiu-iiished posteriorly with 

 a few wart-like protuberances, olive-brown, marbled, 

 especially towards the side, dorsal hiatus pale, edges 

 faint reddish brown, irregularly painted on both sides 

 with very black-bro\vn variously shaped spots, some- 

 times sprinkled in the vicinity, and an intense blotch 

 of the same coloiu- at the posterior end, base olive 

 ash-broi\Ti, teeth black-brown, columella stained with 

 biu'nt brown. 



Testa junior. 



Testa junior ventricosissivia, palUde cinereo-fusca, longltudi- 

 naliter pecuUariter midata, macula atro-fuscd supra

Younger shell very ventricose, pale ash-brown, longitudi- 

 nally peculiarly waved, with a black brown blotch 

 above the posterior extremity.

mtb. ? 



It will be seen by the foregoing description how mate- 

 rially this shell varies fi'om the Ci/praa leiicostoma, which 

 might at fii-st sight be easily mistaken for it. The base of' 

 the Ci/praa mus is of an olive ash-brown colom- without 

 any appearance of spots, there are always a few short teeth 

 in the colimieUa, and the outer teeth are veiy much more 

 defined ; there is also a gi-eat pecidiarity in the general 

 colouring of the shell which is distributed into waves like 

 a rippled cloud.

The snow-flecked Cowry. Shell oblong-ovate, rather 

 thick, extremities short, a little recm-ved, columeUar 

 teeth fine ; back pale fidvous-brown, promiscuously 

 flecked with snow spots, and specks of various size, 

 teeth and base yellowish white, dorsal hiatus rather 

 wide, sometimes confusedly branched, approximating 

 to the right side.

Cypraa dama, Kiener (Periy haud recognitus.) 

 Eah. ? 



An excellent species, and admii-ably figured in the 

 Zoological Jom-nal. From Cypraa vitellus, with which it 

 might be confounded, it ditfers by its more oblong form, 

 more irregidar and confused assemblage of spots and 

 specks, and entire absence of arenaceous strise ; the colu- 

 meUar teeth are also longer and finer, and the colour a 

 pecidiar fidvous bay. From Cyprxa melanosio)aa, which 

 is also destitute of arenaceous stria;, it dift'ers materiaDy in 

 form, and the spots, which in that species are raised, are 

 of a totally difli'erent colour and character.
