exploration of a limited field, those who have but little leisure

295. Natica Chenmitzii. 



Synonymy. 



The synonymy of this species was overlooked until too late 

 to be completed. With the partial data now before us, it 

 appears to be Pfeiffer's N. Chemmtzii, which, and N. unifasciata 

 Lam., and N. lurida Phil., were included by Koch (Zeitschr. 

 fur Malak. 1844. p. 154) in the Chemnitzian species N. maroc- 

 cana. the N. marochiensis of Gmelin, not of Lamarck. Proba- 

 bly it is the N. maroccana of Menke in his catalogue of Mazat- 

 lan shells, in Zeitschr. fur Malak. 1847, p. 179. 



Station. On soft mud near low water mark.
