60 SUPPLEMENT TO THE CRAG MOLLUSCA. 



being somewhat less cylindrical, and in the ornamentation ; the ribs being less curved, 

 and the spiral striae on the lower part of the volution more prominent or distinct. The 

 outer lip of my specimen is unfortunately not quite perfect. 



Chemnitzia filosa. Crag Moll., vol. i, p. 82, Tab. X, fig. 7. 



This is probably the same as Parthenia varicosa, Forbes, from the iEgean, but that 

 specific name having been employed by Basterot for a different shell, apparently of this 

 genus, I have retained the name Jilosa originally given in my catalogue. 



Chemnitzia elegantior, S. Wood. Crag Moll., vol. i, p. 81, Tab. X, fig. 5 (as Ch. 



elegantissima). 



Locality. Cor. Crag, Sutton. Red Crag, Walton. 



This shell was referred to Chemnitzia elegantissima, Mont., in the ' Crag Mollusca,' 

 but the ribs are straight, though inclined, but not curved or flexuous, such as those upon 

 elegantissima. I think therefore that it must be treated as distinct, and I propose to call 

 it Ch. elegantior. Mr. Bell has shown me a portion of a specimen from the Red Crag of 

 Walton (see Otlostomia lactea in Bell's list ' Ann. and Mag.,' May, 1871), which appears 

 to be specifically the same as my own from the Coralline Crag. I am unable to say 

 whether the elegantissima of Woodward's Norwich Crag list be this shell or Montague's 

 elegantissima. 



Chemnitzia internodula, S. Wood. Crag Moll., vol. i, p. 81, Tab. X, fig. 6. 



Localities. Cor. Crag, Sutton. Red Crag, Sutton, and Walton, and Butley (Bell). 

 Fluvio-marine Crag, Bramerton. Middle Glacial, Hopton and Billockby. 



This shell has occurred, but very rarely, in the Fluvio-marine Crag at Bramerton, and 

 several imperfect specimens of it have occurred in the Middle Glacial of Billockby and 

 Hopton. I have not met with it from any of the localities of the Chillesford bed or 

 Lower Glacial Sands. I understand that it has been found living in the Mediterranean, 

 but have not seen the shell. 



Chemnitzia rufa, Philippi. Crag Moll., vol. i, p. 79, Tab. X, fig. 2. 



The author of ' Brit. Conch.' (vol. iv, p. 163) seems to doubt the correctness of my 

 assignment, and I have in consequence again examined my specimens. I still believe my 

 Coralline Crag shell to be identical with the recent British species of that name. I have also
