VENUS. 



Plate XV. 



Species 56. (Mus. Cumnis;.) 



Venus lyra. Ven. testa orbiculari-ovaid, snbventricosd, 

 fidvescente-alhd, rufescejite-fusco uiidaid et maculaid, 

 conceufrice Uraid, litis niimcrosis, snhcallosis, Icevibus, 

 subrefexis. 



The harp Venus. Shell nibiciilarly ovate, rather ventri- 

 cose, fulvous-white, waved and spotted with red- 

 brown, concentrically ridg-ed, ridges numerous, 

 rather callous, smooth, a little reflected. 



Hanley, Pro. Zool. Soc. 1844, p. 161. Recent Shells, 

 App. 360. pi. 16. f. 21. 



Hab. Gvdf of Guinea. 



I give this species, but doubt exceedingly whether it is 

 not the same as V. crenulata. It is an established fact in 

 the geographical distribution of mollusks that West Africa 

 possesses many species common to the West Indies and 

 Mazatlan. 



Species 57. (Mus. Cuming.) 



Venus nodosa. Ven. testd i/lobosd, sordide albd autful- 

 vescente, concentrice costatd, costis subdistantibus, ob- 

 tuse tiintidis, verrucoso-tiiberculatis, lunula rufo-fnscd, 

 area ligamenti rvfo-fusco latii striyatd. 



The noduled Venus. Shell globose, dull-white or yel- 

 lowish, concentrically ribbed, ribs rather distant, ob- 

 tuselv swollen, wart-tuberclcd, lunule I'cd-brown, 

 ligamentary area broadly striped with red-brown. 



Dunker, Moll. Guin. p. 57. 

 Venus tuberosa, Deshayes. 



Hab. St. Vincent, AVest Africa. 



This apparently characteristic species is probably a 

 strongly warted form of the European /'. verrucosa. 



Species 58. (Mus. Cuming.) 



Venus pilula. Ven. testd orbiculari-ovatd, tumido-ven- 

 trico-iu, fnlvescente-albd, carneo-fusco promiscue tinctd, 

 concentrice Uratd, liris subobtiisis, inlerstitiis concavis, 

 concentrice elevato-striatis, Imudd parvd, ared liga- 

 menti rufo-fusco strifjald. 



The little-ball Venus. Shell orbicularly ovate, tu- 

 midly ventricose, fulvous-white, promiscuously stained 



with flesh-brown, concentrically ridged, ridges rather 

 obtuse, interstices concave, sculptured with raised 

 stria;, lunule small, ligamentary area striped with 

 red-brown. 



ITab. 



Closely allied to Dr. (iould's /'. toreuina, but the eon- 

 centric ridges are not warted, and the luuule is smaller. 



Species 59. (Mus. Cuming.) 



Venus Stutchburii. Ven. testd oblijue cordatd, postice 

 subproducfd,albidd,ferruffineo-tiitctdpostice,prcesertiiii 

 intus, violaceo tinctd, radiatim, temdliratd, concentrice 

 corrugato-striatd, lunnld et ared ligamenti snbindis- 

 tinctis. 



Stutchbury's Venus. Shell obliquely cordate, rather 

 produced posteriorly, whitish, tinged with r\isl, 

 posteriorly tinged with violet, especially within, 

 radiately finely ridged, concentrically corrugately 

 striated, lunule and ligamentary area rather in- 

 distinct. 



Gray, Wood, Ind. Test. Supp. pi. 3. f. 4. 



Hab. Sandwich Islands. 



A shell of solid growth, tinged within on the posterior 

 side with deep violet. It comes very near to the Cali- 

 fornian /'. cnllosa, Conrad, of which specimens have been 

 found also at the Sandwich Islands. 



Species 60. (Mus. Cuming.) 



Venus muscaria. Ven. testd pectinalo-ovatd, subcom- 

 pressd, fuhescente, cinereo-violaceo radiatim aspersd, 

 radiatim crebriliratd, concentrice, dense crcnato-lirata, 

 lun aid suhindistinctd. 



The fly-dotted Venus. Shell pectinately ovate, rather 

 compressed, fulvous, radiately sprinkled with ash- 

 violet, closely radiately ridged, concentrically densely 

 crenately ridged, hnude rather indistinct. 



Ilab. ? 



An extremely interesting species, most claboratdy 



sculptured throughout. 



June. 1863.
