Poey mentions a specimen 47 mill, long, but the ordinary size is 

 about 40 mill. It is closely allied to L. fasciatits, with which Arango 

 unites it, but may be distinguished by the more compressed or con- 

 tracted last whorl, and the particular pattern of coloring, which does 

 not vary materially in the small series of some 23 specimens before 

 me. Still, there are certain forms of fasciatus which approach 

 blainianus, and when full series from the region adjacent to its local- 

 ity are collected, I do not have much doubt that blainianus will be 

 given subspecih'c rather than specific rank.

 less distinctly truncate at base. Soft anatomy unknown.
