Species 134. (Mils. Gaskoin.) 



CytR/EA fusca. Ci/pr. testa, ovatd, latere dextro subhi- 

 crassato, trausversim undique costatd, costis tenuibus 

 impressione dorsali obsoletd ; undique fused.

 Trivea fii-ica. Gray. 



Ilnh. Gallapagos Islands, and Bay of Guayaquil ; Cuming. 



There is some character in the eolotiring of this species, 

 it being of an uniform dull brown without any tinge of that 

 dark crimson which is so conspicuous in the C. sanguinea. 



Species 135. (l\Ius. Cuming.) 



Cyfr.ea Adamsonii. Ci/pr. testd Oi'idiformi, soUdiusculd, 

 latere dextro cra.sso, marginato ; transvei'mn undique 

 erebricostatd, costis IcevUms, extremitatibus subrostratis, 

 productis : albd, aurantio-fusco couspicue maculatd. 



Adamsos's Cowrey. Shell Ovulum-shaped, rather solid, 

 right side thick and mai'gincd ; transversely closely 

 ribbed thi-oughout, ribs smooth, extremities slightly 

 beaked, produced ; white, conspicuously blotched

Gray; Sowerby, Conch. lUus. Cypra:ad;c, no. 107- f. 7. 



Hab. Isle of Capul, Pliilippines ; Cuming. 



An extremely characteristic species and the nearest ap- 

 proach in foi-m to the genus Ovulum. 



Species 136. (Mus. Cuming.) 



Cypr^ea nivea. Cypr. testd globosd, extremitatibus valde 

 obtusis, transversim undique costatd, costis angustis, 

 corrugatis, sulproininentibus, dorso sulco lineari im- 

 presso ; pelhicido-albd. 



The snow-white Cowrey. Shell globose, extremities 

 very obtuse, transversely ribbed throughout, ribs 

 narrow, wrinkled, rather prominent, back impressed 

 with a linear groove ; transparent wliite. 



Gray; Zool. Journal, vol. iii. p. 369. 



Hab. ? 



This species has a peculiar globose form, very like that 

 of a coffee-berry. M. Kiener has figm-ed a C. nivea for 

 the C. scabriuscula of Gray, which is Lamarck's C. oryza. 



Species 137. (Mus. Gaskoin.) 



Cypr,ea producta. Cypr. testa ovatd, lateribus subdila- 

 tatis, cdremitatibus peculiariter productis, ba-si depressd, 

 columella acutanguld ; transversim undique tenuicos- 

 tatd, impressione dorsali mclld ; albd. 



The produced Cowrey. Shell ovate, sides a little 

 dilated, extremities pecidiarly produced, base de- 

 pressed, columella sharp-angled; transversely finely 

 ribbed throughout, with no dorsal impression ; white. 



Gaskoin, Pro, Zool. Soc, 1835, p. 200. 



Hab. ? 



A white shell of very peeidiar form, approximating nearest 

 to that of the brown Cyprma satiguinea.

Cypr^a australis. Cypr. testd oblonyo-ovatd, teuuicidd, 

 paulnlum injlatd, apice subconspicuo, latere dextro mar-

 bus grandibus duabus vet trilms subirregulariter picto, 

 extremitatibus roseis. 



The southern Cowrey. Shell oblong-ovate, rather 

 thin, a little inflated, apes rather conspicuous, right 

 side marginated ; transversely very finely ribbed 

 thi'oughout, ribs smooth above, rather obsolete, with 

 no dorsal impression, aperture rather wide ; whitish, 

 somewhat irregularly painted with two or three light 

 brown blotches, extremities tinged with rose.

Distinguished by its colom'iug and light inflated growth. 



Species 139. (Mus. Gaskoin.) 



Cypr^a microdon. Cypr. testd subelougato-ovatd, plano-
