TRITON. 



Plate III. 



Species 7. (Mus. Cuming.) 



Triton clavator. Trit. testd clavaformi, epidermide 

 temii rugulosd indutd ; varicibus duobus, subrotundis ; 

 spird breviuseuld ; anfractibus superne angulatis, in- 

 fra rotundatis, transversim costatis, costis crenatis, 

 superioribus tuberculatis, tubercu/is compressis, seta- 

 rum eristd ornatis, longitudinaliter flexuose digestis, 

 in/erne evanidis, costarum inlerstitiis striatis, striis 

 elevatis, plus minusve interruptis ; albidd, varicibus 

 fuscescente partim tinctis ; columella rugosd, labro 

 intus rugoso-denticulato, utroque vivide luteo-coc- 

 cineo ; canali longissimo, subcontorto. 



The club Triton. Shell club-shaped, covered with a 

 thin wrinkled epidermis ; varices two in number, 

 round ; spire rather short ; whorls angulated at 

 the upper part, rounded beneath, transversely 

 ribbed; ribs crenated, upper ribs tuberculated, tu- 

 bercles compressed, ornamented with a tuft of 

 bristles, arranged longitudinally in a flexuous di- 

 rection, disappearing interiorly, interstices between 

 the ribs striated, striae raised, more or less inter- 

 rupted ; whitish, varices partially stained with 

 brown ; columella wrinkled, lip rugosely denticu- 

 lated within, both vividly stained with yellowish 

 scarlet ; canal very long, rather twisted.

 Ranularia longirostra, Schumacher. 



Hub. Island of Burias, Philippines (found in sandy mud 

 at the depth of seven fathoms) ; Cuming. 



This well-known species appears to have been but 

 imperfectly figured hitherto ; neither Chemnitz nor 

 Kiener's figures convey any idea of the rich scarlet 

 which the specimen here figured exhibits in the mouth ; 

 the tufts of bristles upon the tubercles of the last whorl 

 form another interesting feature, but this is a character 

 rarely to be met with, on account of the difficulty of pre- 

 serving them. 



The shell represented in Sowerby's ' Genera' under 

 the above title, also in my ' Conch. Systematica,' vol. ii. 

 pi. 243. f. 3. (to both of which figures M. Deshayes 

 unfortunately refers in his new edition of Lamarck, 

 vol. ix. p. 635), is not the Triton clavator, but a new 



and very distinct species represented in the followir 

 plate, Fig. 11, a and b (Triton exilis). 



Species 8. (Mus. Cuming.) 

 Triton caxaliferus. Trit. testd clavaformi, ventri- 

 cosd, varice unico, rotunda ; spird breviuseuld; a»- 

 frac/ibus rotundis, superne profundi- depresso-eanali- 



culatis, longitudinaliter p/icato-nodulosis, transversim 

 costatis, costis biliratis, lird exilissimd interveniente ; 

 alba, columella fortiter rugosd, labro intus rugoso- 

 denticulato ; canali longissimo, graci/i. 

 The canaliculated Triton. Shell club-shaped, ven- 

 tricose, with a single round varix on the last whorl ; 

 spire rather short ; whorls round, deeply depressly 

 canaliculated at the upper part, longitudinally pli- 

 cately noduled, transversely ribbed ; ribs double- 

 ridged, with a very fine delicate ridge running be- 

 tween them ; white, columella strongly wrinkled, 

 lip rugosely denticulated within ; canal very long, 

 slender.

 Mure,v caudatus, Gmelin. 

 Tritonium caudatum, PfeifFer. 

 Hab. China. 



According to the strict rule of priority, the specific- 

 title of caudatus should be applied to this shell ; but the 

 name used by Lamarck is so singularly characteristic of 

 its leading peculiarity, the remarkable hollow channel 

 round the top oi each whorl, that I do not hesitate to 

 maintain it. The name of caudatus has moreover been 

 applied by Say to another species, and I think the law 

 of priority should be waived when a change would so 

 entirely subvert the names in popular use. 



Species 9. (Mus. Cuming.) 

 Triton nodiferus. Trit. testd ovato-conicd, tubteformi, 

 inferne ventricosd, valde inftatd, epidermide tenuissi- 

 mii sparsim indutd ; varicibus undecim ant duodecim, 

 nodiferis ; spird breviuseuld, acuminata ; anfractibus 

 eonvexis, subirregulariter convolutis, transversim sub- 

 obsolete liratis, in medio nodorum seriebus duabus 

 cinyulatis, nodis anfracttis ultimi subevanidis. an-
