 This elegantly formed species, which is painted through- 

 out with close-set slightly waved red lines, has a particu- 

 larly columnar spiral callosity. It has also a shelly oper- 

 culum.

Natica melttuostoiiia, var. b, Lamarck. 

 Hab. San Nicolas, Island of Zebu, Philippines (on the 

 reefs) ; Cuniiiig. 

 It may still be doubted whether this species is not a 

 variety of N. melanostomu ; it is, however, generally of [ 

 shorter and more square growth, and they arc from dif- 

 ferent localities. !

 Natica sterci/s-MUScarum, Enc. Methodique. 



Hab. Mediterranean. 



Distinguished by its characteristic painting of red dots, 



which in N. maculata, of the same typical form, from the 



same locality, are represented by confused blotches.
