Species 29. (Mus. Cuming.) 



PuRPnEA LINEATA. PuTp. testd ovatd, tenui, ventricosd, 

 spird hreeiusculd, acuta; anfractibus transversim un- 

 dique striatis, miperne acute angulatk, ad angulmn pli- 

 cato-nodosis, nodis subcompressis, infra funiculis obsolete

 tiird ampld,fauce subtiliter liratd, labro tenui; luteo- 

 albicante ; funieulis castaneis, columella labrique mar- 

 gine internd aurantio-rufa. 



The lineated Purpura. Shell ovate, thin, ventricose, 

 spire rather short, acute ; whorls transversely striated 

 tlu'oughout, sharply angulated, plicately nodided at 

 the angle, nodides rather compressed, encircled be- 

 neath w\i\\ rather irregidarly distant cords, which are 

 obsoletely nodiferous ; aperture large, interior finely 

 ridged, lip thin; yeUoivish white, cords chesnut 

 brown, columella and inner side of the lip orange-red.

 Bitccinum lineatum, Lamarck. 



Eab. ? 



This remarkable shell which is admii-ably figm-ed in the 

 ' Encyclopcdie Methodique ' PL 400 f. 6. a, b. was included 

 by Lamarck in the genus Buccinum ; M. Kiener has, how- 

 ever, very properly removed it to Purpura. 



Species 30. (Mus. Cuming.) 



Purpura imperialis. Purp. testa ovatd, bad ampliter 

 undiilicatd, spird acute tiirritd ; anfractibus transversim 

 undique striatis, superne angulatis, spinis squanupformi- 

 bus prominentibus subrecurvis conspicue biseriatim einc- 

 tis, spinis apiceni versus obsolete ; luteo-albicante, aper- 

 turmfauce cmruleo-fusco subindistincte fasciatd. 



The imperial Purpura. Shell ovate, largely urnbdi- 

 cated at the base, spii'o shai'ply tuiTeted; whorls 

 transversely striated throughout, angulated at the 

 upper part, conspicuously encii'cled with two rows of 

 prominent scale-like spines a little recui'ved, spines 

 obsolete towards the apex ; yellowish white, interior 

 of the aperture somewhat indistinctly banded with 

 blueish brown.

Hab. ? 



How M. Kiener can possibly discover any specific rela- 



tion between the shells which he has figured as varieties 

 under the above title, I cannot imagine. The P. impe- 

 rialu, which he correctly figm-es at Pig. 39. is aUied rather 

 to the P. carinifera, the keels of that species being deve- 

 loped in this into a diadem of recurved spines ; the shell 

 represented at Fig. 39. a, is of a different form, and ex- 

 hibits quite another design of sculpture. 



Species 31. (Mus. Cuming.) 



Purpura KiosauiFOEiiis. Purp. testa fusiformi-ovatd, 

 subscalariformi, transversim undique elevato-striatis, 

 anfractibus medio itni- vel biseriatim carinatis et tuber- 

 culatis, spira: suturis profundis, lamellis crispatis erectis 

 concentrice decussatis, labro superne sinuato ; olivaceo- 

 viridi, albo vel carulescente zonatd, aperturm fauce in- 

 terdum fasciatd. 



The kiosk-shaped Purpura. Shell fusifoi-mly ovate, 

 somewhat scalariform, transversely elevately striateil 

 throughout, whorls encu-cled round the middle with 

 one or two keels and rows of tubercles, sutui-es of the 

 spire deep, concentrically crossed mth erect crisped 

 lamellffi, lip sinuated at the suture ; olive-green, 

 zoned with white or pale blue, interior of the apertiu'c 

 sometimes banded with black-brown. 



DucLOs, Annales Sci. Nat. vol. xxvi. pi. 1. f 5. 



Hab. Bay of Panama (on rocky places at low water); 

 Cimiing. 



The locality of New Holland cited by M. Kiener for 

 this species, is, I think, a veiy doubtfid one ; it was col- 

 lected by Ml-. Cuming at the Bay of Panama. 



Species 32. (Mus. Cimiing.) 



Purpura D'Orbignyi. Purp. testd fusiformi-ovatd, basi 

 umbilicatd, anfractibus transversim liratis, liris promi- 

 nentibus subdistantibus, superne convexo-angulatis, ad 

 angulmn biseriatim tubercidatis, tubercidis compressis, 

 superioribus prominentioribus ; alba, ferrugineo-fusco, 

 apicem versus saturatiore, plus minusve tinctd, epider- 

 niide crassd fibrosa indutd, aperturd alba. 



D'Orbigny's Purpura. Shell fusiformly ovate, umbdi- 

 cated at the base, whorls transversely ridged, ridges 

 prominent, rather distant, convexly angidated at the 

 upper part, encircled at the angle with two rows of 

 compressed tubercles, of which the upper are the 



AuOTst, 1846.
