So much narrower in proportion to its length than the preceding 

 species as to justify the distinction, which has not been made with- 

 out hesitation. Found in coarse black sand at seven fathoms.

 Hab. Guacomayo, Amer. Merid. H. Cuming legit. 

 The only specimen we have seen is in Mr. Cuming's collection ; 

 it bears a very near resemblance to the common West Indian spe- 

 cies named Sc. muricata by Kiener, from which it differs in having 

 the angle of the varices elevated into a tooth or point. It is also a 

 thinner shell, with the laminated varices narrower. Found in sandy 

 mud at a depth of eleven fathoms. 



Scalaria venosa, Thes. Conch, part. 4. pi. 33. f. 72, 73. Seal,

 angustatis ; aperturd rotundatd, colore inter varices pallide fulvo. 

 Hab. Nevis, India, occidentali. 



Remarkable for the shape of the varices, which are turned back- 

 ward and rounded, giving the appearance of tumid veins ; the inter- 

 stices, which are narrow, are of a delicate fawn-colour.

 Hab. Ins. Masbate, Philippinarum. H. Cuming legit. 

 A beautiful species, with ventricose whorls, which are distin- 

 guished by a very deep suture. The varices are thin, close, regular 

 and oblique. The colour is pale brown or dull white, with two bands 

 of deeper or paler brown. Found in sandy mud at five fathoms.
