Plate XVIII. 



(Figures considerably magnified.) 



Species 76. (Mus. Cuming.) 

 Triton sculptilis. Trit. testa oblongo-turritd, varice 

 nulla ; spird exsertd ; anfractibus longitudinaliter 

 costellatis, costellis angustis, interstitiis strife elevatis 

 cancel/atis, anfracttis ultimi parte inferiori conopeo 

 carinteformi prominente peculiariter ornatd ; albidd, 

 suturis fuscis ; columelld Itevi ; canali brevissimo. 

 The carved Triton. Shell oblong- turreted, with no 

 varix ; spire exserted ; whorls longitudinally ribbed, 

 ribs narrow, interstices cancellated with raised 

 stria 1 , lower portion of the last whorl peculiarly 

 ornamented with a prominent keel-shaped canopy ; 

 whitish, sutures brown ; columella smooth ; canal 

 very short.

Hub. Island of Caput, Philippines (found under stones 

 at low water) ; Cuming. 

 In addition to the above account of this beautiful 

 species, it may be noticed that the transverse stria? are 

 brown upon the ribs and white in the interstices ; the 

 sutures are brown in consequence of the whorls being 

 encircled with a brown line just at the point where one 

 whorl lodges in its spiral growth upon the other, over 

 the basal canopy, as if to mark out the exact plan of 

 convolution. 



Species 77. (Mus. Cuming.) 



Triton eximius. Trit. testd oblongo-turritd, varice 

 mild ; spird acuminatd ; anfractibus costellis minutis 

 eximie cancellatis, longitudinalibus majoribus, valde 

 remotioribus ; albd, fuscescente obscure fasciatd ; ca- 

 nali brevissimo. 



The delicate Triton. Shell oblong-turreted, with no 

 varix ; spire acuminated ; whorls delicately cancel- 

 lated with minute ribs, of which the longitudinal 

 are larger and much wider apart ; white, obscurely 

 banded with very light brown ; canal very short.

Hab. Lord Hood's Island, Pacific Ocean (on the reefs), 

 and Island of Capul, Philippines (under stones at 

 low water) ; Cuming. 

 A neatly cancellated, almost colourless, shell. 



Species 78. (Mus. Cuming.) 

 Triton egregius. Trit. testd elongato-ovatd, varice 

 nulhl ; spini acutd ; anfractibus longitudinaliter cos- 

 tatis, striis elevatis transversis cancellatis; albd, 

 costis medio albis, supra et infra fuscis; canali 

 brevi, reeurvo. 

 The chosen Triton. Shell elongately ovate, with no 

 varix ; spire acute ; whorls longitudinally ribbed, 



cancellated with transverse raised striae ; white. 



ribs white in the middle, brown above and below ; 



canal short, recurved,

 Hab. Island of Masbate, Philippines (found under stones 



at low water) ; Cuming. 

 The style and arrangement of the sculpture is not 

 much unlike that of the preceding species ; the shell is 

 however larger, more globose, and has a very pretty 

 appearance, arising from the dark brown upper and lower 

 portions of the ribs being crossed by white striae. 



Species 79. (Mus. Cuming.) 



Triton lanceolatus. Trit. testd elongato-turritd, vari- 

 cibus octo, longitudinaliter oblique costellatd, costellis 

 minutis, confertis, striis elevatis transversis subtilis- 

 sim'e cancel/atis; rosea -albicante, aurantio-fusco spar- 

 sim macu/atd ; canali brevissimo. 



The little lance-like Triton. Shell elongately tur- 

 reted, with eight varices, longitudinally obliquely 

 ribbed, ribs very small, close-set, very finely can- 

 cellated with raised transverse stria; ; pinkish white, 

 blotched here and there with light orange-brown ; 

 canal very short.

Hab. West Indies. 



This species is of much more common occurrence 



than either of the two following, which, though so nearly 



allied, are peculiarly distinct. 



Species 80. (Mus. Cuming.) 

 Triton antiquatus. Trit. testd elongato-turritd, vari- 

 cibus novenis ; spird acuminatd ; anfractibus sub- 

 irregu/ariter convo/utis, longitudinaliter subtilissime 

 costellatis, costellis irregii/aribus, nunc obliquis, nunc 

 subundulat is, junta suturam peculiariter mucronatis, 

 striis transversis undique sculptis ; roseo-albicante, 

 semipe/lueidd, caricibus aurantio-fusco media u/iinia- 

 culatis ; canali brevissimo; aperturie fuuce purpurea . 

 The antiquated Triton. Shell elongately turreted, 

 nine varices ; spire acuminated ; whorls somewhat 

 irregularly convoluted, longitudinally very finely 

 ribbed, ribs irregular, now oblique, now a little 

 waved, peculiarly pointed next the suture, every- 

 where engraved with fine transverse striae ; pinkish 

 white, semitransparent, varices marked in the mid- 

 dle with a single orange-brown spot ; canal very 

 short ; interior of the aperture tinged with purple.
