lated species, on the other hand, seem to form a well marked and very 

 natural section, or subgenus of the Volutinoe, more charactenstic of the 

 Cretaceous than of the Tertiary rocks, whose shells can generally be 

 distinguished without much difficulty by their slender, fusiform shape, 

 their spirally striated or cancellated whorls, their thickened outer lip and 

 comparatively prominent columellar folds. 



Stoliczka, as befoi-o stated, holds that the name Fulguraria should be 

 applied to these shells, on the ground that they do not ditfer in any es- 

 sential particular from the tj'pe of that genus, the ^ oluta fulminata of 

 Lamarck, and this view has been provisionally adopted by the writer. 

 Conrad, it is true, says that V. Navarroensis belongs to his subgenus 

 Rustellites, * but even if the correctness of this assertion be admitted, and 

 the objection to its use, as suggesting affinities that do not exist, be waived, 

 it still seems highly probable that JRostelUtes is merely a synonym of 

 Fulyuraria.

Sucia Islands, in Division A. ; J. Eichardson, 1874. Two specimens, 

 both with most of the test preserved, but with the beaked extremity 

 broken off. The best of these is figured, as the species was described 

 from casts which did not shew the surface ornamentation. The 

 sculpture consists of revolving ridges or fine rounded ribs, which 

 are placed at unequal distances from each other, and these are crossed 

 by crowded, minute and parallel, transverse, raised striations, also, on 

 the angle or angles of the whorls only, by coarse distant plications. 

 Thei'e are six or seven whorls; those of the spire are angular or 

 subcarinated below the middle, and bear a single row of rather distant 

 nodes or tubercles. The body whorl is concavely constricted near the 

 middle, the constriction being bounded, both above and below, by a 

 nodose and obtuse keel.
