NATICA. 51 



Var. FIBROSA, Souleyct. Fig. It. 



The spiral bands distinct. 

 Var. SUCCINEOIDES, Reeve. Fig. 18. 



Shell white, without markings, columelhi and umbilicus 

 chocolate-colored. 



N. SIMMS, Dcsh. PI 21, figs. 19, 20. 



Flesh-white, marbled with fawn-colored or light olivaceous 

 rather obscure markings, with three or four revolving series of 

 short irregular chestnut streaks and spots ; umbilicus and colu- 

 niella chocolate-colored. Length, 1-2 inches. 



Philippines, New Zealand, Viti Islands. 



Embraces N. simioides, Recluz, of Reeve, and probably N. 

 Samarensis, Recluz both of them unfigured. N. Bernardii, 

 Recluz (fig. 20), appears to be a slight color- variety. Its habitat 

 is " ? Gulf of Mexico," doubtless an error.

 fine waved revolving striae ; whitish, obscurely wide-banded with 

 faded chestnut, columella and umbilicus chocolate-colored. 



Length, 1*5 inches. Australia. 



Very like N. melanostoma in form and coloring, but has not 

 the polished surface of the latter species, and is immediately 

 recognized by the very close thread-like revolving striae. 



N. PRIAMUS, Recluz. PI. 22, fig. 23. 



Thin, inflated, polished, pale chestnut- or fawn-color, with two 

 spiral series of small chestnut spots ; callus thin, but filling the 

 umbilicus, chocolate-colored. Length, T5 inches.

 ture brownish white. Length, 1*5-2 inches.
