12 ZOOLOGY OF THE VOYAGE OF THE SULPHUR. 



rently constant manner before the antepenult whorl, leaving each to consist of 

 about three entire whorls. 



26. Triton antiquatus, Hinds, 1. c. (Plate IV. fig. 7, 8.) Testa elongata, turrita, subcylin- 

 dracea, lineis decussantibus textili, prope suturam costis evanidis ; spira, aperturam duplo vel triplo 

 superante ; apice eroso ; apertura parva, subquadrata, pallida ; labio interno antice valde producto. 



Inhab. New Ireland. Among the coarse sand at low-water. 



27. Teiton fictilis, Hinds, 1. c. (Plate IV. fig. 11, 12.) Testa ovata, solidula, cinerea; anfrac- 

 tibus senis rotundatis, longitrorsum oblique plico-eostatis, transversim tenuiter striatis ; spira aper- 

 turam vix superante ; apertura callosa, contractata, polita, intus laevigata. 



Inhab. Cape of Good Hope. Dredged on the L'Agulhas bank, in between 

 fifty and sixty fathoms. 



28. Triton anomalus, Hinds, 1. c. (Plate IV. fig. 13, 14.) Testa ovata, fusca, longitrorsum 

 costata, evaricosa, lineis transversis elevatis cancellata, ; spira aperturam aequante ; sutura valida ; 

 apertura ovali, pallida ; canali breviusculo. 



Inhab. Island of Quibo, Veragua. On the sandy shore at low-water. 



This little shell presents no appearance of a varix, but the character of the 

 mouth and outer lip, and the general contour is such, that it unquestionably is 

 fittest placed here. Indeed, its appearance is very similar to that of the preceding. 



29. Triton lignarius, Broderip, Proceed. Zool. Soc. 1833, p. 5. (Plate IV. fig. 15, 16.) 



Inhab. Monte Christi, west coast of America. In seven fathoms, sandy 

 mud. 



This is a very interesting species, and as it is not frequent in collections, 

 figures have been given. It seems liable to considerable variation in the number 

 and relation of its varices. 



Ranella. Lamarck. 



30. Ranella calif vrnica, Hinds, Ann. Nat. Hist. v. 11, p. 255, (Plate II. fig. 4,5.) Testa 

 ovata, ventricosa ; anfractibus uniseriatim tuberculatis, transversim granoso-striatis ; tuberculis conicis 

 subdistantibus ; varicibus magnis cavernosis ; anfractu ultimo multiseriatim obsolete tuberculato, 

 fasciis duabus angustis purpureis cincto ; apertura alba, ; labio externo crenato et dentato, interno 

 transversim striato. 



Inhab. San Diego, California. 



Not unlike the American tropical species, R. ventricosa. This is, however, 

 a larger and heavier shell, is without any disposition to tuberculation in the 

 vicinity of the suture, the varices are much bolder and cavernous, the tubercles on
