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. 
CuEmnivzia FILosa. Crag Moll., vol. i, p. 82, Tab. X, fig. 7. 
This is probably the same as Parthenia varicosa, Forbes, from the Aigean, but that 
specific name having been employed by Basterot for a different shell, apparently of this 
genus, I have retained the name jiJosa 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. \ 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 Odostomia 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. 1 understand that it has been found living in the Mediterranean, 
but have not seen the shell. 
Curmnitzia 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. JI still believe my 
Coralline Crag shell to be identical with the recent British species of that name. I have also
