NATICA. 19 



N. Sagratana, d'Orb. PL 3, figs. 44-46. 



Whitish, with light chestnut, narrow zigzag lines, interrupted 

 by a white band on the periphery ; columellar callus chestnut or 

 violaceous, nearly covering; the umbilicus. Length, 5-'7'5 inches. 

 West Indies, Madeira, W. Africa, 



Mediterranean Sea. 



N. fulminea, Risso, name preoccupied b}' Gmelin for another 

 species; ? N. Jfamyjiulata, Requien ; N. pulchella, Pfeiffer (fig. 

 40) ; N. nivea, Anton ; N. Jamaicensis, C. B. Adams; N.filosa, 

 Phil. (fig. 45), described as lineolata, preoccupied by Deshaycs 

 for a fossil species, are synonj-ms. 



N. VENUSTULA, Phil. PI. 3, figs. 47-49. 



Shell shining, white with sparse chestnut lineations, somewhat 

 zigzag, interrupted by a white band at the suture and a broader 

 one on the periphery ; columellar callus white, filling the umbili- 

 cus except a narrow chink. Length, 8 mill. 



Habitat unknown. 



The lines are not so close as in the last species, the sutural 

 area is without them, the callus is uncolored and more nearly 

 filjs the umbilicus ; still, I doubt its distinctness. N. Baijani, 

 Jouss. (fig. 49), is apparently- a S3-non3'm. 



N. Tratllii, Reeve. PL 3, fig. 50. 



Rather solid, somewhat depressed globose, umbilicus large, 

 partly filled by the brownish columellar callus ; whitish, painted 

 throughout with waved oblique dark chestnut lines. 



Length, 12 mill. 



Malacca. 



More depressed than N. Sagraiana, the lineations wider apart, 

 not interrupted by anj' peripheral band, etc. 



N. MOZAiCA, Sowb. PL 3, figs. 51, 52. 



Ovate, whitish with four series of ovate, obliqueh' quadrate 

 chestnut markings ; columellar callus wide, white, covering the 

 umbilicus. Length, 15 mill. 



Hab. unknown. 



The form and callus remind one of the smaller species of 

 Neritina.
