Species 43. (Mus. Cuming.) 



Venus sugill.^ta. Ven. testa subb-iyono-ovatd, fulves- 

 ceiite-grised, purpurea sparsim undato-Vmeatd, iimboiii- 

 6us vivide purpureis, liris tcuuibiis, uudique subacute 

 clathratd, lunuld ampld, area llijamenti angustd, amba- 

 bus intense castanets. 



The bruised Venus. Shell somewhat triangularly 

 ovate, fulvous-grey, sparingly wave-liueated with pur- 

 ple, umboes deep purple, everywhere rather sharply 

 latticed with fine ridges, lunule large, ligamentary area 

 narrow, both dark-chestnut. 



ffai. California. 



I cannot identify this species with any hitherto de- 

 scribed. Its shining purple umboes, finely latticed sculp- 

 ture, and dark-stained lunule and ligamentary area are 

 quite peculiar. 



Species 44. (Mus. Cuming.) 



Venus simillima. Veu. testa snhcordato-ovatd, depres- 

 siusculd, sordidefuscescente-albd, concentrice laminato- 

 liratd, liris subconfertis, plicatis, subrejiexis, postice 

 appressis, radiutim tenitiliratis, liris duplicihus. 



The very like Venus. Shell somewhat cordately ovate, 

 rather depressed, dull brownish-white, concentrically 

 laminately ridged, ridges ratlier close-set, puckered, a 

 little reflected, posteriorly appressed, radiately finely 

 ridged, ridges duplicate.

Hab. San Diego, California. 



Resembling the beautiful V. compta in detail of sculp- 

 ture, but of a distinct form, without any of its charac- 

 teristic colouring. 



Fig. 45. (ilus. Cuming.) 



The shell here represented was drawn as anew species; 

 but it appears to be an unusually gibbous form of V. 

 casina, with the concentric sculpture more slenderly lami- 

 nated and crowded. 



Fig. 46. (ilus. Cuming.) 



A very distinct variety, fi'om the Gulf of California, of 

 V. crenidata, of which a typical specimen of the W est 

 Indian form is represented at Plate X. f. 33. In the Ca- 

 lifornian variety the shell is more globose, and beautifully 

 coloured in the interior with purple-rose. 



Species 47. (Mus. Cuming.) 



Venus gibbosula. J'i'u. testa pectinato-orbiculari, al- 

 bidd, violaceo-i/riseo ii/ictd et obscure fasciatd, uit- 

 dique obtuse corrugiito-reticulatd, pracipue ad latus 

 anticmn, latere postico radiativi sulcato-striato, luiiidd 

 et area ligameuti subindisliiictis. 



The gibbous Venus. Shell pectinately orbicular, 

 whitish, stained and obscurely banded with violet- 

 grey, everywhere obtusely wrinkle-reticulated, es- 

 pecially on the anterior side, posterior side radiately 

 groove-striated, lunule and ligamentary area rather 

 indistinct. 



Deshayes, MS. in Mus. Cuming. 



Ilab. ? 



An interesting, delicately tinted species, of rather solid 

 growth, sculptured with a network of obtuse wrinkled 

 ridges. 



Species 48. (Mus. Cuming.) 



Venus co.mpta. Ven. testa aljbremato-cordatd, subtri- 

 gond, depressd, crassd, sordide fuho-alhd, rufo-castaneo 

 radiatim liiieari-stric/atd, concentricii luminato-costatd, 

 costis dislantibas, area Ugnmenti ampld, acute ex- 

 cacatd. 



The neat Venus. Shell shortly cordate, somewhat tri- 

 angular, depressed, thick, dull fulvous-white, ra- 

 diately linearly streaked with reddish-chestnut, con- 

 centrically laminately ribbed, ribs distant, ligamen- 

 tary area large, sharply excavated.
