TRITON.— Plate XVI. 



Lamarck's collection, seems to have been no less un- 

 fortunate. 



Species 65. (Fig. a and b, Mus. Stainforth.) 

 Triton Soverbii. Trit. testd elongato-turritd, crassd, 

 solidd, varicibus quindenis planiusculis ; spird acumi- 

 nata ; anfractibus longltudlnaliter creberrime subob- 

 solete sulcatis, granu/is seriatim dispositis, lineisque 

 brunneis excavatis , binis, undlque cingulatis ; aurantio- 

 fuscescente, fusco variegatd, macularum fuscarum 

 seriebus duabus distantibus ornatd ; columelld lavi, 

 callosltate superne armatd, encaustlcd latissime ex- 

 pansd ; canali brevissimo, labro intiis subtilissime den- 

 ticulato. 

 Sowerby's Triton. Shell elongately turreted, thick, 

 solid, with fifteen rather flattened varices ; spire 

 acuminated ; whorls longitudinally very closely 

 rather obsoletely grooved, everywhere encircled 

 with rows of granules, and brown excavated lines, 

 ranged two and two ; orange-brown, variegated 

 with brown, and ornamented with two distant rows 

 of square brown spots ; columella smooth, armed 

 with a callosity at the upper part, the enamel being 

 very widely expanded ; canal very short, lip very 

 finely denticulated. 



Triton lineatus, Sowerby (not Broderip), Pro. Zool. 

 Soc, 1833. 

 Hab. Gallapagos Islands, Pacific Ocean (found in sandy 

 mud at the depth of six fathoms) ; Cuming. 

 I dedicate this shell with a great deal of pleasure to 

 Mr. Sowerby, because he was the first to distinguish it 

 in a proper manner from the preceding species, with 

 which it was confounded by Lamarck. Chemnitz pub- 

 lished a very accurate figure of it in the ' Conchylien 

 Cabinet,' vol. x. pi. 162. f. 1552 and 1553, as a most 

 elegant species of spotted Murex, " Species elegantlsslma 

 Muriels maculati," and the vivid dark brown lines which 



encircle its entire surface in pairs render it not unworthy 

 of the title. 



The name selected by Mr. Sowerby for this interest- 

 ing shell was applied by Mr. Broderip only a few months 

 before to another species (vide Sp. 4), the description of 

 which was probably not in type. 



Species 66. (Mus. Cuming.) 



Triton distortus. Trit. testd oblongo-turritd, crassd, 

 solidd, varicibus novenis oblique invlcem subsequen- 

 tibus ; spird peculiar iter tortuosd ; anfractibus seria- 

 tim creberrime granulosis, juxta suturam granoso- 

 cremdatis, infra impresso-lavibus ; roseo-albicante, 

 fusco va)i'e maculatd et nebidosd ; columelld Itevi, en- 

 causticd expansd, subgranosd ; canali brevisslmo ; 

 labro intiis subtilissime denticulato. 



The distorted Triton. Shell oblong-turreted, thick, 

 solid, with nine varices obliquely following one 

 under the other ; spire peculiarly twisted ; whorls 

 covered with close-set rows of granules, granulously 

 crenulated next the suture, impressly smooth im- 

 mediately under ; pinkish white, variously spotted 

 and clouded with brown ; columella smooth, enamel 

 spread over, slightly granulous ; canal very short ; 

 lip very finely denticulated within. 



Schubert and Wagner, Conchylien Cab. (Martini and 

 Chemnitz), Supp., p. 138. pi. 231. f. 4074 and 4075. 



Sowerby, Pro. Zool. Soc, 1833. 



Hab. Island of Annaa, Pacific Ocean (found on the 

 reefs) ; Cuming. 



Mr. Sowerby seems not to have been aware that this 

 curiously distorted shell was described, four years before 

 the publication of his account of it, by Schubert and 

 Wagner; as however, singularly enough, he applied 

 the same name to it, all confusion has been fortunately 

 avoided.
