appeal to me. A large number of well-defined groups, considered as genera, 

 makes a much more workable system, and that is all that can be asked 

 for at present in connection with these minutiae. As far as I have gone, 

 I have found little difficulty in recognizing at sight species of Oscilla, Pyrgu- 

 lina, Miralda, and Odostomella, simply to cite the first names called to mind. 

 Such an ultra-conservative worker as Melvill (Proc. Mai. Soc. (Lond.), vol. ix, 

 p. 171, 1910) rebelled at Dall and Bartsch's retrogressive action, and I would 

 consider the arrangement given by Melvill a better and more natural one 

 than Dall and Bartsch's. 



On p. 197 Melvill notes that Dall and Bartsch failed to distinguish 

 between Turbonilla and Odostomia (sensu lato), a fact I had independently 

 observed. Again, on p. 194 Melvill points out that Cingulina and Oscilla, 

 which Dall and Bartsch confused, were easily separable, another item I 

 independently recorded. 



I have not yet carefully criticized all the Neozelanic forms, but would 

 advocate the acceptance of the subgenera quoted by Suter as of generic 

 value.
