CERITHIUM. 135 



C. LEMNISCATUM, Quoy. PI. 24, fig. 38. 



Varicose, roughly granulated in revolving series, with usually 

 single intermediate lirse, in the middle of each whorl a few of the 

 granules are larger, more like tubercles ; whitish, more or less speck- 

 led or clouded with chocolate, frequently with a chocolate band on 

 the spire, and tw r o bands on the body whorl. Length, 1*25 in. 



Philippines, Viti Islands. 



C. TRAILLII, Sowb. PI. 25, figs. 47-54, 56, 59. 



Varicose, w r ith spiral beaded striae alternating with smaller plain 

 ones ; yellowish white, or clouded with chestnut or chocolate, the 

 beads chestnut or chocolate color. Length, 1*5 in. 



Singapore ; Java; Philippines. 



Differs from the preceding species in its finer, more regular spiral 

 sculpture, variegated coloring, and absence of tubercles : it is possi- 

 bly only a variety of it. C. nitidum, Sowb. (fig. 54) = gentile, 

 Bayle, and / C. baccatum, Hombr. et Jacq. (fig. 59), are synonyms. 



Var. LUCTUOSUM, Hombr. et Jacq. Fig. 56. 



Stouter and smoother, the granules more distant and fewer ; nearly 

 uniform w r hite, the granules milk-white. 



Var. ALTERNATUM, Sowb. Figs. 48-50. 



The granules larger, spiny, shell white, or chocolate color, or 

 white with interstitial bands of chocolate. 



Philippines. 



C. robustum, Sowb. (fig. 50), is a synonym. 



Var. SPLENDENS, Sowb. Figs. 53, 51, 52. 



Granules larger, spiny, one or more series more developed, so that 

 the whorls apppear subangulate and the lip margin crenulated ; 

 whitish to chocolate color, on the lighter colored specimens the spines 

 are chestnut colored. 



Philippines. 



C. purpurascens, Sowb. (figs. 51, 52), is a synonym. 



C. HANLEYI, Sowb. PL 24, fig. 42. 



Shell with rounded longitudinal plications, varicose, slightly nod- 

 uled by spiral sculpture ; yellowish brow r n, with regular chestnut or 

 chocolate spiral lines. Length, 22 mill. 



Hob. unknown. 



C. rubrolineatum, Sowb. (figured), is precisely like Hanleyi, 

 which was first described of the two on the same page of the 

 Thesaurus. Why Sowerby abandoned the latter name in favor of 

 the former, I cannot imagine.
