Much shorter and stouter than the other species which 

 most nearly resemble it in other respects. The varices are 

 numerous and prominent, some of them doubled ; the whorls 

 are few, the suture deep, the umbilicus large. Three bands 

 of a reddish colour are visible between the ribs. Brought 

 from Masbate, Philippines, by Mr. Cunning ; but a white 

 variety in the collection of Mr. Sowerby is ticketed " East 

 Indies." 



32. Sc. lineolata (45, 16, 48.) Kiener. 



T. tenui, Sc. trilineatee simili, sed magis elongata ; fasciis 

 obscuris. 



Figured by Kiener as a variety of the preceding species, but 

 a much more elongated shell. Brought from Masbate, Phil- 

 lippines. by M,-. Cuming, and from Japan by Dr. Sibbald. 



33. Sc. rubro-lineata. (pL xxxiv. f. 83, 84.) Sow Jun.. 

 T. pyramidali, laevi, sub-ventricosa ; anfractibus rotundatis 



prominentibus, gradatim crescentibus ; varicibus numerosis 

 sub-eequalibus, validis ; apertura ovali ; labio interno antice 

 subquadrato ; umbilico magno : colore pallide fulvo linea 

 rubra vel vusca in medio anfractuum. 



The whorls of this species are very prominent, the varices, 

 numerous, regular, and thick, as in Sc. trilineata, but the 

 form is more elongated, and the umbilicus very much larger. 

 The specimens, the smaller of which has a bright red line in 

 the centre of the whorls, are from the cabinet of Miss Saul. 



34. Sc. crassa. (pi. xxxiii. f. 55.) Sow. Jun. Z. P. 1844. 



T. pyramidali ventricosa, laevi ; anfractibus rotundatis, 

 gradatim crescentibus ; varicibus sub-numerosis, inaequalibus, 

 laminatis, ad suturam magis expansis, nonnullis in medio 

 anfractum sub-obsoletis : apertura magna ; labio interno 

 antice subquadrato ; umbilico parvo : colore, inter varices 

 pallide fulvo, fasciis binis latis ; una prope suturam, altera 

 in medio anfractuum. Variat testa alba, opaca. 



Much larger and more solid than Sc. lineolata, with the 

 ribs unequally lami.iated, spreading more at the suture 

 than at the middle of the whorls. The whorls are not so 

 prominent as in Sc. rubro-lineata, and tiie umbilicus is much 

 smaller. Of the four specimens brought from Catanuan, Isl. 

 Luzon, Philippines, by Mr. Cuming, two have two broad bands 

 in the upper part and near the centre of the whorls.
