TRITON.— Plate XVII. 



oblong, with four or five varices ; spire middling ; 

 ■whorls impressed at the upper part, transversely 

 striated and ridged, decussated with larger and 

 more prominent longitudinal ribs, noduled at the 

 point of crossing ; orange-brown, lower portion of 

 the whorls articulated with brown between the 

 nodules ; columella excavated, scarcely wrinkled ; 

 canal very short.

Hab. ? 



Care must be taken not to confound this shell with 



the lesser New Holland species, Triton Quoyi. 



Species 72. (Mus. Cuming.) 

 Triton reticulatus. Trit. testa elongato-turritd, vari- 



cibus undecim aut duodecim; spird acutd; anfractibus 



crebcrrhne reticularis ; fuscescente, fusco vane tinctd; 



columelld excavatd, lavi ; canali brevissimo, recurvo. 

 The reticulated Triton. Shell elongately turreted, 



with eleven or twelve varices ; spire sharp ; whorls 



very closely reticulated ; light brown, variously 



stained with brown ; columella excavated, smooth ; 



canal very short, recurved.

After attentively comparing the specimens described 

 by Sowerby under the respective titles of Tritones reti- 

 culatus and Mediterraneus , I am unable to discover any 

 specific difference between them. 



Species 73. (Mus. Hanley.) 



Triton Ceylonensis. Trit. testd gracili-turritd, sub- 

 distorld, varicibus rudibus ad duodecim planulatis ; 

 spird acuminata, subtortuosd ; anfractibus liris lon- 

 gitudinalibus creberrimis subindistinctis, subtilissim'e 

 granulosis, sculptis ; roseo-albicanle, fuscescente ex- 

 imi'e bulteatd, maculatci, et vari'c tinctd; columelld 

 excavatd, politd ; canali brevissimo, recurvo. 



The Ceylon Triton. Shell slenderly turreted, some- 

 what distorted, with about twelve rude, flattened 

 varices ; spire acuminated, a little twisted ; whorls 

 sculptured with very finely granulated, Tather indi- 

 stinct, close-set, longitudinal ridges ; pinkish white, 

 belted, spotted, and variously stained with light 

 brown ; columella excavated, polished ; canal very 

 short, recurved ; lip denticulated within. 



Sowerby, Pro. Zool. Soc, 1833. 

 Hab. Island of Ceylon. 



The granules in this species are close-set, but of the 

 same fine, delicate character as those of the T. nitidulus. 



Species 74. (Fig. a and b, Mus. Cuming.) 

 Triton tortuosus. Trit. testd oblongo-turritd, suban- 

 gustd, varicibus octo oblique invicem subsequentibus ; 

 spird tortuosd ; anfractibus granulis parvis subtiliter 

 reticulatis; lutescente, maculis fuscis grandibus, 

 longitudinaliter undatis, eleganter pictd ; columelld 

 excavatd, subgranulosd ; canali brevissimo, recurvo. 

 The twisted Triton. Shell oblong-turreted, rather 

 narrow, with eight varices obliquely following one 

 under the other ; spire twisted ; whorls finely reti- 

 culated with small granules ; yellowish, elegantly 

 painted with large longitudinally-waved brown 

 spots ; columella excavated, slightly granuled ; 

 canal very short, recurved. 

 Reeve, Pro. Zool. Soc, 1844. 



Hab. Island of Burias, Philippines (found under stones 

 at low water) ; Cuming. 

 This interesting species approximates very closely to 

 the Triton distortus ; it differs in being of a more deli- 

 cate and slender form, in the granules being less promi- 

 nent, and in the peculiar waved style of the painting. 



Species 75. (Mus. Cuming.) 



Triton niveus. Trit. testd rotundato-ovatd, varicibus 

 senis septemve indistinctis ; spird acuminatd, acutd ; 

 anfractibus ventricosis, liris prominentibus reticulatis, 

 longitudinalibus concentricis latioribus ; lamind colu- 

 mellari tenui, striatd ; nived ; canali brevi, tortuoso- 

 recurvo ; labro tenui ; apertures fauce elevato- 

 slriatd. 



The snow-white Triton. Shell rotundately ovate, 

 with six or seven indistinct varices ; spire acumi- 

 nated, sharp; whorls ventricose, reticulated with 

 prominent ridges, of which the longitudinal are 

 concentric and wider apart ; snowy white ; colu- 

 mellar lamina thin, striated ; canal short, recurved 

 in a twisted manner; lip thin; interior of the 

 aperture elevately striated.

Hab ? 



It would have perhaps been more correct if Pfeiffer 

 had adopted the specific name of albus for this little 

 species of Triton, but as Martini's nomenclature is so 

 immethodical, I think its priority unimportant.
