VANIKORO. 69 



F. disparilis, Desh. (fig. 83), are synonyms. N. Sigaretiformis, 

 Potiez, has been considered sjmonymous ; it is really unrecog- 

 nizable. I add as a s^^nonyni V. granifera^ Pease (fig. tl), from 

 Ins. Jarvis. The granular appearance of the original figure 

 (copied by me) is an exaggeration, and does not agree with the 

 types before me. 



Y. SULCATA, d'Orb. PI. 29, figs. 18, 79. 



Revolving riblets most prominent, but rendered somewhat 

 granular by the crossing of the growth sculpture ; umbilicus 

 moderate. Diam. 9 mill. 



West Indiea. 



Only distinguished from forms of the last species by locality. 

 I figure a very young shell, in which the spiral ribs are much 

 more prominent than the}^ remain in the later whorls. V. anomala, 

 Adams (uufigured), is probably the same. 



y. STRIATA, d'Orb. PL 29, figs. 80, 81. 



Rather thin, with fine spiral raised lines ; umbilicus moderate. 

 Diam. 8 mill. 



Cuba. 

 Probably only a variety of V. sulcata. 



V. lamellosa, d'Orb (fig. 81), is probably the young of this 

 species, and V. oxychone and V. Vitrinseformis, Morch (uu- 

 figured), synonyms. 



V. ROSEA, Recluz. PI. 29, fig. 82. 



Cancellated, pink; umbilicus widel}^ open. Diam. 5 mill. 



Is evidently a juvenile shell. 



Moluccas. 

 V. ELATA, Sowb. PI. 29, fig. 84. 



Elevated, thin, very finely decussated, umbilicus narrow. 

 Diam. 9, alt. 10 mill. 



China Sea. 

 V. ACUTA, Recluz. PL 29, figs. 85, 86. 



Thin, white, subpellucid, very delicately sculptured, the spiral 

 lines the most prominent; spire acute, umbilicus wide, aperture 

 somewhat obliquely produced. Diam. T-10 mill. 



Lord Hood^s Is., Cape Natal, Moluccas. 



The above rather incongruous localities are given by Recluz ; 

 Morch adds West Indies in considering the species a synonym
