Native. Paludal. Only of late separated from G. flui- 

 tans, its area and census being in consequence very im- 

 perfectly known at present. It is recorded or known in 

 Somerset (Rev. W. H. Coleman), North Hants (H. C. 

 Watson), Sussex (INIr. Borrer), Kent GMr. Thomas Sansom !), 

 Surrey (H. C. Watson), Hertford (Rev. W. H. Coleman), 

 Cambridge (Rev. R. C. Douglas !), Gloucester (Mr. F. J. A. 

 Hort), Stafford (Rev. R. C. Douglas !), Flint (H. C.Watson), 

 Leicester (Miss Kia-by), Lincoln (H. C. Watson), Durham 

 (Mr. Hort), Orkney (Mr. J. T. Syme); perhaps with some 

 other counties also. These counties suffice to show an 

 area which embraces almost the whole length and breadth 

 of Britain, but with very large interspaces between the 

 stations ascertained ; so that the provincial and comital 

 estimates are only rough guesses.
