PUEPURA.— Plate XII. 



Species 66. (Mus. Taylor.) 



PuRPUEA TEXTiLiosA. Purp. testd ovatd, ventricosd, 

 iransversim uncUque obsolete costatd, costis superji- 

 ciariis, irregularihits, coiifertis, interditiis mhindistincte 

 pertusis, aperturd ampld ; sordide albd, lalro intus

The interwoven Purpura. Shell ovate, ventricose, 

 transversely obsoletely ribbed throughout, ribs super- 

 ficial, irregular, close-set, interstices rather indistinctly 

 punctiu'ed, apertm-e large ; dull white, lip palely 

 tinged within with orange. 



Lamarck, Anim. sans vert. (Deshayes' edit.), vol.x. p. 77. 



Hab. New Holland. 



Amply distinguished from the P. succincta by the super- 

 ficial character of the encu-chng ribs, the P. textiliosa yet 

 passes into that species thi'ough a succession of interme- 

 diate states. 



Species 67. (Mus. Hanley.) 



Purpura bisebialis. Purp. testd ohlougo-ovatd, spird 

 conico-acutd, anfractihus trmisversim teiiuiss-mii inciso- 

 striatis, superne depressis, biseriatlm tuberculatis ; pal- 

 lide grised, striis fuscis, fusco irregnlariter strigatd, 

 columelld vivide rufd, apertures fauce paUidd, rnfo 

 prope labruM tinctd. 



The double row purpura. SheU oblong-ovate, spire 

 coiiically acute, whorls encircled with fine engi'aved 

 striae, depressed round the upper part, beneath which 

 are two rows of tubercles ; pale gray colom-, strise 

 brown, irregularly streaked with brown, colimiella 

 bright red, interior of the apertm-e pale, tinged with 

 red towards the lip. 



De Blainville, Nouv. Ann. du Mus. PI. 11. Fig. 11, 



Hab. ? 



I venture to refer this shell to P. biserialis of De Blain- 

 ville ; it answers with peculiar accm-acy to his description, 

 and is quite distinct from any other species of the present 

 monograph. 



Species 68. (Mus. Cuming.) 



Purpura sauAMULOSA. Purp. testd globoso-ovatd, basem 

 versus attenuatd, spird brevissimd, depressd ; atifi'acti- 

 hus SJiperne rotundatis, liris subtilibus tniuutli squamu- 

 losis tindique creberrime cinctis; albd, columelld et 

 apertura fauce pallide violaceis. 



The FINELY SCALED PURPURA. Shell globosely ovate, 

 attenuated towards the base, spire rather short, de- 

 pressed ; whorls rounded at the upper part, very 

 closely encircled throughout with fine minutely 

 scaled ridges ; white, columella and interior of the 

 aperture pale violet. 



Hab. Island of Ticao, Philippines (on the reefs at low 

 water ) ; Cuming. 

 This delicately sculptured species has very much the 

 form of the P. violacea, from Taheite, but it is perfectly 

 distinct ; the entire suiface is encncled with minutely 

 scaled ridges similar in pattern to those of the beautiful 

 little Murex squamulosus of PhUippi, and the colour of the 

 mouth is a pale violet of a diiferent tint. 



Species 69. (Mus. Cuming.) 



Purpura Madreporarum. Purp. testd depresso-ovatd, 

 spird brevissimd, interdum oculatd; iransversim tenuis- 

 sirne striatd, scabrd ; aperturd ampld, marginiius latis- 

 siirie dilatatis, columelld, plano-depressd ; albd, colu- 

 melldvmidepurpureo-molaced,apertur(B fauce purpureo- 

 violaceo partim tinctd. 

 The Madrepore Purpura. Shell depressly ovate, 

 spire very short, sometimes concealed ; transversely 

 very finely striated, rough ; apertm-e large, margins 

 very wdely dilated, columella flatly depressed ; white, 

 columella rich purple-violet, interior of the aperture 

 partially stained with pm-ple \'iolet. 

 Sowebby, Genera of Shells, Purpura. 



Purpura monodonta Quoy and Gaimard. 

 Hab. Eastern Seas (upon madrepores). 



I adopt Mr. Sowerby's name for this interesting parasite, 

 first, because he introduced it simultaneously if not prior 

 to that of M M. Quoy and Gaimard, and secondly because 

 the name assigned to it by those naturabsts is a very 

 inappropriate one, there being nothing in the structure of 

 the shell that can be desimated a tooth. 



Species 70. (Mus. Cuming.) 



Purpura violacea. Purp. testd ovatd, crassd, ponderosa, 

 basi attenuatd, subcaiialiculatd, spird, brevissimd; 

 Iransversim obsolete striatd, scabrd ; albd, columella et 

 apertures fauce vivide purpureo-violaceis 



The violet Purpura. SheU pyriformly ovate, thick, 

 ponderous, attenuated and somewhat chaimelled at 

 the base, spire very short, transversely obsoletely 

 striated, rough ; white, columella and interior of the 

 apertm-e rich purple violet. 



KiENER, Icon. Coq. viv. p. 77. pi. 19. f. 57. 



Murex Neriloideus, Chemnitz (not of Linnseus). 



Fusus NeritoideiK, Enc. Mcth. 



Pyrula Neriloidea, Lamarck. 



Purpura Neritoidm, Quoy and Gaimard. 



Hab. Taheite (on the reefs at low water) ; Cuming. 



This well-known shell may be easily distinguished 

 from the Purpura squamulosa, by its rude structure and 

 deep purple violet colouring.
