254 Oldham : Cheshire Land and Fresh-imter Mollusca. 



taylori — a species of peculiar interest to local naturalists, seeing 

 that it was made known to science from Cheshire examples — 

 is well established in one canal, and may be expected to extend 

 its range by colonizing other canals which are connected with 

 it. 



The symbol ' ! ' implies that T have seen the shells referred to. 

 The arrangement, and, in the main, the nomenclature 

 adopted are those of the list published in 1904 by the Con- 

 chological Society of Great Britain and Ireland. 

 I have used the following abbreviations :— 

 B.R.L. — Mr. B. R. Lucas. 

 CO. — Charles Oldham. 

 H.G.B. — The Rev. H. G. Barnacle.

 form of* this species is unknown in Britain. I recorded it 

 for Cheshire (' Nat.', 1896, p. 113), in ignorance of the precise 

 characters which distinguish it from the var. luduosa. I have 

 taken the variety in many places in the Goyt Valley, between
