Species 5. (Fig. a, 6, Mus. Cuming.) 



LuciNA INTEERUPTA. Luc. testd orbiciilari, convexd, noU- 

 diuscttld, concentrice creierrime tenuiliraid, liris brevi- 

 fjus, obtusis, Vuieis impressis inarjnidisiatiiibus ad latera 

 ab umbo)iibus promiscue radiatd, luuuld parvd, cordatd, 

 subprofundi excavatd; alba, prope cardinem utrinque 

 rosed, intiis vivide luted. 



The interrupted Lucina. Shell orbicular, convex, 

 rather solid, concentrically very closely finely ridged, 

 ridges short, obtuse, promiscuonsly rayed at the sides

Cytlierea interrupta, Lamarck, Anim. sans vert. (Desliayes' 

 edit.) vol. vi. p. 318. 



Hab. Buoly Island, Torres Straits ; Jukes. 



A delicately sculptured species, belonging to the same 

 type as those of the preceding plate, and similarly rose- 

 coloured on either side of the hinge. 



M. Deshaycs is mistaken in supposing this to be a 

 variety of L. liyeriiia, from Senegal. 



Species 6. (jMus. Cuming.) 



Lucina argentea. Luc. iesld suborbicidari, convexo-de- 

 pressd, ad latera vix arigidatd, temdculd, concentrice 

 acute temdliratd, liris inaquidistautibus, interstitiis 

 radiatim eximii; corniffatis, cardiiiis deiitibus cidlosis, 

 subohsoletis ; intus e.rt usque subpellucido-albd. 



The silvery Lucina. Shell nearly orbicular, convexly 

 depressed, scarcely angled at the sides, rather thin, 

 concentrically sharply finely ridged, ridges inequidis- 

 tant, interstices radiately delicately corrugate, teeth 

 of the hinge callous, almost obsolete ; semitrans- 

 parent white within and without. 



Hab. Moluccas. 



A flattened semipclluci 



concentrically sculptured. 



Jver-white shell verv 



Species 7. (Fig. a, b, Mus. Cuming.) 

 Lucina Jamaicensis. Luc. testa suborbicultiri, coin- 

 pressd, ad latera ab umbonibus excavato-angulatd, cou- 



dinis dentibus centralibus fere obsoletis, lateraiibus 

 prominentibus, compressis, erectis ; fuscescente-lacted, 

 intus vivide rufescente-croced, interdum, autem raru, 

 intus extusque alba. 



The Jamaica Lucina. Shell nearly orbicular, com- 

 pressed, excavately angled from the umboes at the 

 sides, concentrically lameUated, lamellae short, rather 

 distant, central teeth of the hinge almost obsolete, 

 lateral teeth prominent, compressed, erect ; brownish 

 cream-colour, bright reddish-saffron in the interior, 

 sometimes, but rarely, white within and without. 



Venus Jamaicensis, Chemnitz, Conch. Cab. vol. vii. p. 24. 

 pi. 38. f. 408-9. 

 Lucina Jamaicensis, Lamaivk. 



Ilab. Jamaica; Gosse. 



This well-known species was called by the early French 



conchologists, the Apricot, after the rich colouring of the 



interior ; there is, however, a well-marked white variety, 



such as that represented at Fig. 7 b, and which is mostly 



smaller in size. 



Species 8. (Mus. Cuming.) 



Lucina bicornis. Luc. testd globoso-orbiculari, ventri- 

 cosd, ab umbonibus utrinque leviter excavatd, concentrice 

 tenuistriatd, rugosd, lunula cordatd, conspicue excavatd, 

 cardine dente unicd centrali, parvd, duabus lateral/bus 

 compi-essis, prominentibus, erectis ; fuscescente-ladrd, 

 intus ru/escente-croceo pullide tinctd. 



The two-horned Lucina. Shell globosely orbicidar, 

 ventricose, slightly excavated on both sides from the 

 umboes, concentrically finely striated, rough, lunuie 

 cordate, conspicuously excavated, hinge with a small 

 single central tooth, and two prominent compressed 

 erect lateral ones ; brownish cream-colour, faintly 

 tinged with reddish saffron-colour within. 



Ihb. Island of Ticao, Philipjuues (in fine coral sand at 

 low water) ; Cuming. 

 Very similar to the following species, except in having 



two strongly developed lateral teeth.
