TRITON. 



Plate XVI. 



Species 57. (Fig. a and b, Mus. Cuming.) 



Triton clathratus. Trit. testd interdum oblongo-, 

 interdum abbreviato-turritd, crassit, varicibus unde- 

 cents; spird acuminatd; anfractibus liris subpro- 

 minentibus creberrime clathratis, /iris ad decussatio- 

 nem fort iter granulosis ; albidd aut fuscescente, fusco 

 balteutd et maculatd ; columelhi subrugosd ; canali 

 brevissimo, recurvo ; labro intus denticulato. 



The latticed Triton. Shell sometimes oblong, some- 

 times shortly turreted, thick, with about eleven 

 varices ; spire acuminated ; whorls closely latticed 

 with rather prominent ridges, ridges strongly gra- 

 nulated at the point of crossing ; whitish or brown- 

 ish, belted and spotted with brown ; columella 

 slightly wrinkled ; canal very short, recurved ; lip 

 denticulated within.

It was very injudicious, to say the least of it, of Mr. 

 Sowerby to distinguish this shell by a name which had 

 been used by Lamarck and long commonly adopted, in 

 reference to a well-known species of the grimace Tri- 

 tons ; it has however been lately shown by M. Deshayes, 

 that the Triton clathratus of Lamarck was originally pub- 

 lished by De Roissy with the specific title of cancellinus. 



Species 63. (Mus. Cuming.) 



Triton obscurus. Trit. testd elongato-turrita, varL 

 cibus undecenis ; spird acuminatd ; anfractibus trans- 

 versim granulosis, longiluilinalitrr subobsu/ete sulcatis, 

 sulcis creberrimis ; fuscescente, fusco pal Ttdi- balteatd, 

 maculis fuscis quadrat is perpaucis seriatim pictd, va- 

 ricibus fusco maculatis ; columelhi lavi, crassissim'e 

 encausticd ; canali brevissimo, labro intus denticulato. 



The obscure Triton. Shell elongately turreted, with 

 eleven varices ; spire acuminated ; whorls trans- 

 versely granulated, longitudinally rather obsoletely 

 grooved, grooves very close-set ; light brown, palely 

 belted with brown, painted with a very few square 

 brown spots in rows, varices spotted with brown ; 

 columella smooth, very thickly enamelled ; canal 

 very short, lip denticulated within.

This shell may have been probably confounded with 

 the Triton maculosus ; it differs however in not being 

 transversely grooved, in having a different arrangement 

 of the varices, and in other minor particulars. 



Species 64. (Mus. Stainforth.) 



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

 solidd, varicibus quaternis ; spird obtuso-acuminatd ; 

 anfractibus liris angustis subprominentibus creberrime 

 clathratis, liris ad decussationem fortiter granulosis, 

 interstitiis subtilissime striato-cancellatis ; albidd, 

 fusco et aurantio-fuscescente varie tinctd et maculatd ; 

 columella Levi, callositate supernc armatd, encausticd 

 latissime expansd ; canali brevissimo, recurvo ; labro 

 intus denticulato. 



The spotted Triton. Shell oblong-turreted, thick, 

 solid, fourteen varices ; spire obtusely acuminated ; 

 whorls very closely latticed with rather prominent 

 ridges, strongly granulated at the point of crossing, 

 the interstices being extremely finely cancellated 

 with raised stria?; whitish, variously stained and 

 spotted with brown and light orange-brown ; colu- 

 mella smooth, armed with a callosity at the upper 

 part, enamel very widely spread ; canal very short, 

 recurved ; lip denticulated within.

If Lamarck had looked upon the two excellent figures 

 in the ' Conchylien Cabinet,' to which he refers for this 

 species, with the same discrimination as Mr. Sowerby 

 has done, he would have discovered that the shell figured 

 by Chemnitz in the tenth volume, pi. 162. f. 1552 and 

 1553, is quite a distinct species from that figured by- 

 Martini in the fourth volume, pi. 1 32. f. 1257 and 1258. 

 Our contemporary, however, possessed an advantage 

 in having specimens for comparison which his prede- 

 cessor might not have had ; and a conchological icono- 

 grapher of the present day, who had long the care of
