11. Sc. angulata. (pi. xxxii. f. 5.) Say, Boston Ame- 

 rican journal, pi. 27, Sc. Humphreysii ; Kiener ? 



T. ovali, obtusa, lsevi : anfractibus paucis, separatis ; vari- 

 cibus distantibus, crassis, superne angulatis, ad suturam 

 junctis : apertura ovali, labio interno sub-expanso : colore 

 albo. 



Much more oval and obtuse, than Sc. communis, with the 

 whorls much less numerous in proportion to its bulk. It is 

 found in some cabinets labelled " West Indies ;" and is de- 

 scribed by Mr. Say, as an American shell. 



12. Sc. philippinarum. (pi. xxxii. f. 1,2,3.) Sow. Jun.> 

 Zool. Proc. 1844. 



T. elongata, acuminata, laevi; anfractibus numerosis, vix 

 separatis ; varicibus distantibus, tenuis, obliquis, superne vix 

 angulatis, ad suturam junctis : colore inter varices, pallide 

 fulvo, vel castaneo nigricante: variat colore albo. 



As in the case of some of the preceding and following 

 species, the whorls are so far separated, that a fine thread 

 might be passed between them. One variety is of a chesnut 

 colour between the varices, which are white. Brought by Mr. 

 Cuming from Catanuan, Isl. Luzon, and by Mr. Hinds from 

 Ainboyna. 



13. Sc. aculeata. (pi. xxxii. f. 35, 36, and 37.) Soiv*

T. pyramidali, laevi, acuminata ; anfractibus vix separatis ; 

 varicibus laminatis, reflexis, antice sub-rotundatis, prope sutu- 

 ram in dentem acutum productis, ad suturam plicatim junctis: 

 variat varicibus crassis : colore albo, vel pallide fulvo. 



Brought by Mr. Hinds from Hong Kong in China, the 

 straits of Macassar, Malacca, and Amboyna. Also by Mr. 

 Cuming from the Isle of Negroes, and the variety with thick 

 ribs from Catanuan. 



14. Sc. gracilis, (pi. xxxii. f. 33, 34.) Sow. Jun., 

 Zool. Proc. 1844. 



T. aculeata, similima, sed graciliori. 



Brought from Dumaguete, in the Isle of Negroes, by Mr. 

 Cuming, and so much narrower than the preceding species, 

 as perhaps, to justify the distinction which we have hesita- 

 tingly made.
