I wanted to post this again since I foolishly posted it a few hours before last week's list expired. I'm am doing research and writing a paper on the Turbonilla species of the Northwestern Atlantic. These days I note in Rosenberg that Turbonilla interrupta (Totten) has many synonyms. At getting to the bottom of whether or not these other "pseudo-species" are in fact just variations of T. interrupta, I've failed to track down any particular articles arguing the issue. The particular at present invalid species that I'm particularly concerned with is T. areolata (Verrill) and T. vineae (Bartsch). I have Powell's treatment of T. buteonis in 1981. That one is clearly distinct. There are others such as T. winkleyi and T. cascoensis, but I'm primarily focusing on the above 2 species. Does anyone know of the articles where any of these were proclaimed just a variation of T. interrupta? Any help in this regard would be greatly appreciated! -Thanks, Kevin PS.
