276 APPENDIX. 



the description, " with eight spires, striated transversely (longi- 

 tudinally) white " too succinct for positive identification. 



Vol. iii. p. 245. Chemnitzia rufa and fulvocincta. 



An acquaintance with the animals of both these shells enables 

 us at length to declare their specific distinctness ; on this one point 

 we can accord with the views expressed by Mr. Clark in one of his 

 many papers on the Chemnitzice. 



The C. rufa of our work must, consequently, be thus divided. 



C. rufa, Philippi, 



Plate XCIII. fig. 4. 



Reddish ; if banded, the band immediately beneath the sutures ; 

 whorls flat ; suture deep ; ribs straight, bluntish, their intervals 

 distinctly and rather broadly grooved in a spiral direction. 



Melania and Chemnitzia rufa, Philippi. 



Partlienia crenata, Lowe. 



Pyramis crenatus, Brown. 



Odostomia rufa, in part, Jeffreys. 



Cliemnitzia rufa, southern form, British Moll. p. 247. 



Found chiefly in Devonshire (Clark) ; Dorsetshire (S. H.); and 

 the S. W. coast of England, in not very deep water. 



C. fulvocincta, Thompson. 



Plate XCIII. fig. 3, and F F. fig. 4, as rufa. 



White with a single sub-central orange spiral fillet ; whorls 

 flattish, yet a little rounded below ; suture simple though distinct; 

 ribs not oblique, yet a little sinuated, their intervals rather finely 

 grooved in a spiral direction. 



Turritella fulvocincta, Thompson, and Brit. Marine Conch. 



Turbonilla rufa (by typographical error in our synonymy as T. crenata) Loven. 



Chemnitzia fidvocincta, Alder. 



Odostomia rufa in part, Jeffreys. 



Cliemnitzia rufa, northern form, British Moll. iii. p. 240'.
