Sc. replicata, brought by Mr. Cuming from Lord Hood's 

 Island, is a short white shell, with a very acute angle on the 

 upper part of each varix, near the suture. The varices are 

 strongly folded back, so as to form a canal behind each. 



7. Sc. HYALiNA. (pi. xxxii. f. 21, 22.) Sow. Jun., Zool. 

 Proc. 1844. 



T. tenui, glabra ; anfractibus late separatis, angustis ; vari- 

 cibus 6, distantibus, lacqueatis, extantibus; colore albo. 



This elegant httle species has the whorls quite distinct 

 from each other, not even united by the varices ; which are 

 distant, laminated, and beautifully fluted. Brought by Mr. 

 Cuming from Catanuan, Isl. Luzon, Philippines. 



8. Sc. LAXATA. (pi. xxxii, f. 8.) Sow. Jun., Zool. Proc. 



1844. 



T. tenui, Isevi; anfractibus vahde separatis: varicibus 

 numerosis, sub-regularibus, laminatis, simplicibus ; apertvira 

 ovali : colore albo. 



The whorls are separated, as in Sc. hyaHna, but the vari- 

 ces are very numerous and simple. Brought from Catanuan, 

 Isl. Luzon, Philippines, by Mr. Cuming. 



9. Sc. PYRAMiDALis. (pi. xxxii. f. 4.) Sow.. Jun., Zool. 

 Proc, 1844. 



T. pyramidali, acuminata, laevi : anfractibus separatis vari- 

 cibus 9, extantibus, sub-crenulatis, prope suturam in angu- 

 lum acutum productis, ad suturam junctis ; apertura ovali ; 

 labio intemo crasso : colore albo. 



In some respects, resembling Sc. communis, but much less 

 elongated, and with laminated, projecting varices, which have 

 a sharp angle near the suture. 



Brought from Isl. Caminguing, Philippines, by Mr. Cum- 

 mg ; we are also indebted to the Rev. J. F. Stainforth, for the 

 complete specimen, which we have figured. 



10. Sc. COMMUNIS, (pi. xxxii. f. 18, 19, 20, 27, 28.) 

 Lam. Turbo clathrus, Gmel. 



T. elongata, laevi ; anfractibus numerosis, paululum sepa- 

 ratis: varicibus crassis, reflexis, sub-equalibus, sub-recumben- 

 tibus, ad suturam plicatim junctis, colore purpureo fuscoque 

 maculato et fasciato, vel griseo, vel albo. 



There is no reason for supposing, as Gmelin, Dillwyn, and 

 other authors have done, that Linneus had his eye upon this 

 common British species, when describing his Turbo clathrus.
