SOLETELLINA. 



Species 9. (Mus. Cuming.) 



SoLETELLiN.v TRUKCATA. Sol. testd ovalo-trmisversa, 

 peculiariier oblique conlortd, suiaqualiferali, inaequi- 

 valvi, valvd sinktrd ccmvexd, dextrd plana, nigricante- 

 purpured, epidermide olivaeed itidutd, latere aniico 

 rotundato, poslico brevi, laiissimi trnncato. 



The truncated Soletellina. Shell ovaicly transverse, 

 peculiarly obliquely contorted, nearly equilateral, in- 

 equivalve, left valve convex, right flattened, blackish- 

 purple, covered with an olive epidermis, anterior side 

 rounded, posterior short, very broadly truncated. 



Hab. Moluccas. 



An interesting species, distinguished from all others by 

 the flattened growth of the right valve, and by its general 

 oblique contortion. 



Species 10. (Mus. Cuming.) 

 Soletellina siliqva. Sol. testd anguaie tramversd, 

 tenui, aqwlateraU, lavi, carneo-albd, epidermide cor- 

 ned olivaeed translucidd nitente induld, postice pallide 

 biradiatd, latere antico rotundato, postico oblique acu- 

 minato-rotundato . 

 The pod Soletellina. Shell naiTowly transverse, thin, 

 equilateral, smooth, flesh-while, covered with a shin- 

 ing transparent olive horny epidermis, faintly two- 

 rayed on the posterior side, anterior side rounded, 

 posterior obliquely acuminatcly rounded. 

 Hab. New Zealand ; Hart. 



A delicate flesh-tinged shell, covered with a thin trans- 

 parent shining horny epidermis, exhibiting the two pos- 

 terior rays so frequently characteristic of this genus. 



This little species does not present the usual inequality 

 in the form of the lateral extremities, and it is enveloped 

 in an unusually thick transiwrent horny epidermis, re- 

 sembling that of Solemya. 



Species 12. (Mus. Cuming.) 



Soletellina acuminata. f>ul. testd elongato-transverm. 

 inaquilaterali, carulescente-purpured, epidermide ni- 

 gricanle-olivaced indutd, ad umbones erosd, latere an- 

 tico rotundato, postico oblique Jlexuoso-acuminafo, nii- 

 gulum obtnsum rugosum formante. 



The acuminated Soletellina. Shell elongately 

 transverse, inequilateral, bluish-purple, covered with 

 a blackish-olive epidermis, eroded at the umboes, 

 anterior side rounded, posterior obliquely flexuously 

 acuminated, forming an obtuse wrinkled angle. 



Deshayes, MS., Mus. Cuming. 



[lab. Philippine Islands. 



Of rather more rough and solid structure than its allies, 



with a darker epidermis, and conspicuous above all in 



having the posterior extremity obliquely acuminated. 



Species 11. (Mus. Cuming.) 



Soletellina Donacioides. Sol. testd oblongo-transversd, 

 tenui, incequilaterali, Irtvigatd, late castaneo-radiald, 

 epidermide crassd corned translucidd indutd, lateribu^ 

 cBqualiter rotundatis, postico multo breviore. 



The Donax-like Soletellina. Shell oblong-transverse, 

 thin, inequilateral, smootli, broadly chestnut-rayed, 

 covered with a thick, transparent, homy epidermis, 

 sides equally rounded, posterior much the shorter. 



Ilab. Port Adelaide, Australia. 



} Species 13. (Mus. Cuming.) 



1 Soletellina incerta. Sol. testd oblongo-transversd, 

 postice latiore, tenui, ineequilaterali, lavi, epidermide 

 \ tenui corned olivaeed indutd, postice obscure biradiatd, 



latere antico rotundato, postico oblique truncate. 

 I The doubtful Soletellina. Shell oblong-transverse, 

 I broader posteriorly, thin, inequOateral, smooth, co- 



j vered with a thin horny epidermis, obscurely two- 



rayed posteriorly, anterior side rounded, posterior 

 obliquely truncated. 

 Deshayes, MS., Mus. Cuming. 

 ITab. New Zealand ; Strange. 



Of simple form, with the posterior side only very 

 slightly compressly truncated. 



Species 14. (Mus. Cuming.) 

 Soletellina atrata. Sol. testd ovato-transversd, pos- 

 tice latiore, tenui, concentrice striatd, atro-purpured, 

 epidermide corned olivaeed indutd, postice biradiatd, 

 latere aniico rotundato, postico tumidulo, rotundato- 

 triincalo.
