Species 21. (Mus. Saul.) 



Cypr-EA spadicea. Cypr. testa ovato-ohlongd, sulpyri- 

 formi, aiitice attemmtd, aperturd anytidd, deutibiis cras- 

 dusculk, irevibus; clorso spadiceo, latera versus tistu- 

 lato-fusco 7iebulato, guitis niyricnnlibus seriatim undato- 

 marginato, laieribiis rosaceo-albis, obscurissime nigro- 

 guttatis, dentibus basique albis. 



The chesnut-bat Cowet. Shell ovately oblong, some- 

 what pyrifoiin, attenuated anteriorly, apertiu-e narrow, 

 teeth rather thick, short ; back chesnut-bay, clouded 

 towards the sides with burnt brown, edged with a 

 waved row of confused blackish spots, sides pinkish 

 white, showing very obscure dark spots, teeth and 

 base white.

This species may be recognised by its peculiar burnt- 

 brown colom'ing, wliich looks at th'st sight as if it had been 

 artiticially obtained by the action of acid. It is still one 

 of gi-eat rarity, in fine condition, and I have not seen it in 

 any other state than the adidt. The dorsal area of burnt- 

 brown clouding is edged on both sides by a row of con- 

 fused blackish spots ; and I am inclined to think, that du- 

 ring the intermediate state of growth the right side is en- 

 tirely tessellated mth these spots, regidar in size, and 

 neatly equidistant from each other, on a burnt-brown 

 ground ; a faint indication of this style of colouring may 

 be seen thi'ough the wliite coating of the sides, which has, 

 in consequence, a didl pinky appearance. 



Species 22. (Fig. a and b. Mus. Cuming.) 



Cypr^a leucostoma. Cypr. testa depresso-ovatd, crassd, 

 basi turgidd, extremitatibus posterioribiis incrassatk, 

 sinistrd pracipue, aperturd subangustd, cohmielld eden- 

 iuld, labro extenio ardice obsoletissime dentato; dorso 

 cinereo-fnsco, macula castaned elongatd, lined dorsali 

 pallidd ramosd perctirrente, mediopicto; lateribus albi- 

 dis, guttis numerosis ciuereo-fuscis fulvo-nebidatis pro- 

 fuse aspersis, bail albd. 



The white-mouth Cowry. Shell depressly subovate, 

 thick, swoUen at the base, posterior extremities 

 thickened, especially the left, aperture rather narrow, 

 columella destitute of teeth, outer Hp very faintly 



toothed anteriorly; ashy brown, painted along the 

 middle with an elongated chesnut blotch, thi-ough 

 which runs a pale branched dorsal opening; sides 

 whitish, profusely sprinkled ^vith ash-brown fidvous- 

 clouded spots, base white.

The Cyprcna, leucostoma has been very properly distin- 

 guished, by Ml'. Gaskoin, from the CypriBa mus, on ac- 

 count of the following peculiarities. The base is white, 

 the columella is entirely destitute of teeth, and only the 

 faintest indication of teeth is to be foimd on the outer lip. 

 The sides are more distinctly spotted, and the dorsal line 

 has a peculiar branched character. Out of ten or a dozen 

 examples of tliis shell which I have seen within the last few 

 days, there is not the slightest modification of any of these 

 features into those of the Cyprcea mus. I have not seen 

 the shell in an intermediate state of gi'owth, but the colu- 

 mella mostly exhibits a portion of its colouring at that 

 age ; — a close series of concentric brown festoons upon a 

 yeUoivish-white ground. 



Species 23. (Mus. Brit.) 



Cyprjia leucodon. Cypr. testa subpyriformi-ovatd, dorso 

 gibboso, elevato, basi convexd, aperturd postice sinuosd, 

 extremitatibus promiuerdibus, leviter recurvis, dentibus 

 tdrinque fortibus, eloiigatis, insterstitiis profunde sulca- 

 tis ; dorso rufeseente atd flavesceide-fusco, guttis rotun- 

 dis albidh subamplis Jdc iUic asperso, basi pallidiore, 

 striis subtilissimis transverse notatd; dentibus eburneis; 

 Matu dorsali latiuscido, addextrum latus approximante. 



The white-tooth Cowry. Shell somewhat pyriformly 

 ovate, back gibbous, elevated, base convex, aperture 

 sinuous posteriorly, extremities prominent, slightly 

 recurved, teeth strong on both sides, elongated, in- 

 terstices deeply gi-ooved ; back reddish or yellowish- 

 brown, sprinkled here and there with rather large 

 round white spots, base paler, marked transversely 

 with fine striae, teeth ivory white ; dorsal hiatus 

 rather broad, approaching the right side.
