LAMPANIA.— Plate I. 



It may be doubted whether this species is rightly sepa- 

 rated from L. zonalis, because, although it is very much 

 rougher in sculpture, that character is one of degree, and 

 in some specimens it is intermediate. 



Species 5. (Fig. a, b, c, Mus. Cuming.)

The banded Lamfania. Shell subpyrnmidal, rather 

 smooth, banded with brown and black, longitudinally 

 plaited ; whorls angular above the middle, subnodose 

 at the angle, sulcated beneath ; outer lip sinuous,
