TURRITEI-LA. 201 



T. RUBESCENS, Reeve. PI. 61, fig. 02. 



Acuminately turreted ; whorls 13, spirally closely ridged and 

 striated, the first few whorls keeled in the middle, keel quickly 

 vanishing; light reel. Length, -05 inch. 



Bay of Monti j a, West Columbia. 



All the whorls are somewhat prominent in the middle, occupied 

 by the keel in the first few whorls. 



The above is Reeve's description of a young shell which does 

 not appear to possess any special characteristics ; it will possibly 

 prove identical with one of the larger species from the same 

 region.
