KENNARD : ON POMATIAS HABMERT, N.SP. 317 



P. Sarmeri is somewhat worn, and that in this condition the 

 reticulation, if it existed, should be much more apparent. The 

 umbilical region, however, has suffered no detrition, and the absence 

 of reticulation is noteworthy. Since it has lost at least half a whorl, 

 it is rather difficult to compare the relative proportions, but it would 

 appear to be distinctly broader in proportion than P. elegans. 



Eleven species of Pomatias ( Cyclostoma) are cited by Westerlund 

 from the Palsearctic region, and after a careful comparison with all 

 these forms I have failed to identify it, while there is no known 

 extinct form which compares with it. It greatly extends the age 

 of the genus in England, which hitherto has not been found in any 

 deposit older than late Pleistocene, Barrington (Cambridge), Ightham 

 (Kent), and the Happaway Cavern (Devonshire) being the records 

 for that period, though it is known from many Holocene beds. It 

 may be objected that it is unwise to name a rolled and worn 

 shell of which only one example is known, yet it appears to me 

 better to give it a new name rather than list it as Pomatias elegans, 

 var. ?, from which species it distinctly differs.
