We are indebted to M. Quoy, the enterprising naturalist 

 of the Astrolabe, for having rescued this species from the 

 obscurity into which it had fallen in the hands of Lamarck. 

 It was first described and admirably figm'ed, during the 

 last centiuy, by our countryman Mart\Ti in his ' Universal 

 Conchology,' mider the name of Bucciuum liav^trum, or 

 ' Water Scoop Whelk, fi'om New Zealand ' ; Chemnitz 

 afterwards published an excelleut figm-e and description of 

 the species 'with the name oi Buccinum hauritorium, making 

 a needless change in its specific appellation. Lamarck, 

 who was evidently unacquainted with the Purpura Jmus- 

 trum, confounded it vidth the Purpura persica, quoting the 

 foregoing names as synonymes of that species ; a glance 

 at the accompaning figures will, however, show that it is 

 unecessary to institute a comparison. 



Species 7. (Mns. Cuming.) 



Purpura bufo. Purp. testd suborbiculari-ovatd, crassd, 

 spird brevissimd, plus minusve depressd, transversim 

 inciso-striatd et tuberculis subdistantibns, nunc promi- 

 nentibus, nunc fere obsolefis, seriatim armatd ; colu- 

 Jiielld subconcavd, callositate insigni superfie munitd, 

 labro minute dendailato, superne conspicue nnuato ; 

 extus nigricante-fusco Uneatd, columelld et aperturm 

 fauce rufescente-luteis. 



The toad Purpura. Shell somewhat orbicidarly ovate, 

 thick, spire very short, more or less depressed, trans- 



versely deeply striated, and ornamented with rows of 

 rather distant tubercles, wliich are sometimes promi- 

 nent, sometimes almost obsolete ; columella rather 

 concave, furnished at the upper part with a remark- 

 able callosity; lip minutely denticulated, conspicu- 

 ously sinuated at the upper part ; exterior lineated 

 ivith blackish brown, columella and interior of the 

 apertm-e reddish yellow.

Variety /3. 



Testa spird depressiore, tuberculorum seriebzcs supremd et 



infmd prominentiius, callositate crassiore. 

 Shell with the spire more depressed, the uppermost and 



lowest row of tubercles more prominent, and the 



callosity thicker. 



Purpura eallosa, Lamarck. 



Purpura tumida, Schubert and Wagner. 

 Hab. Island ot Corrigidor, mouth of the Bay of Manila 



(on rocks at low water) ; Cuming. 



M. Deshayes charges M. Kiener, in a note at page 70 

 of his edition of the ' Animaux sans vertebres ', of having 

 confounded Lamarck's Purpura eallosa with his P. bufo ; 

 I cannot, however, agree with the learned editor on this 

 subject, iyter a careful comparison of the shells with 

 Lamarck's description, coupled with an examination of the 

 fig-m-es of Petiver and Seba, I am forced to the conclusion 

 that they are the same species in different states. 



M. Kiener describes the Purpura centiqitadrata, Duclos, 

 as being the young of this species, whilst M. Deshayes, on 

 the other hand, considers it distinct ; not having as yet 

 obtained access to the work in which M. Duclos' mono- 

 graph occurs, I am unable at present to ofi^er an opinion. 



Species 8. (Mus. Cuming.) 



Purpura persica. Purp. testd ovatd, bad leuiter attetiuatd, 

 spird brevi, transversim inciso-striatd, striis regularibus, 

 liris intermediii subplanulatis, avfractibus parte supe- 

 riori obsolete biseriatim nodulosd ; columelld medio 

 longitudinaliter excavatd, aperturd perampld, labro 

 simplici, subtiliter denticulato, superne late sinuato ; 

 cinereo-fuscd, zonis albidis fusco-articulatis angustis 

 subdistautibus cingulatd, columelld rubido-luted, aper- 

 tures fauce rufo-albicante, rufo-lineatd.
