NATICA. 19 



N". SAGRAIANA, 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 by Gmelin for another 

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

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

 Phil. (fig. 45), described as lineolata, preoccupied by Deshaj-es 

 for a fossil species, are synonyms. 



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 

 fills the umbilicus ; still, I doubt its distinctness. N. Bayani, 

 Jouss. (fig. 49), is apparently a synonym. 



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 any peripheral band, etc. 



I 

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



Ovate, whitish with four series of ovate, obliquely quadrate 

 chestnut markings ; columellar callus wide, white, covering the 

 umbilicus. Length, 15 mill. 



Hob. unknown. 



The form and callus remind one of the smaller species of 

 Neritina.
