ASHFORD : LIST OF REDCAR L. & F, W. SHELLS. 237 



Limnsea peregra var. ovata. In one pond on Coatham 

 Marshes are fine, very thin examples closely approaching this 

 variety and connecting it with var. aamiinata. 



L. peregra var. labiosa. In one small dyke leading 

 to the main drain across Coatham Marshes there is a general 

 tendency to what I take' to be this variety. The last whorl at 

 the usual termination of its circuit suddenly and considerably 

 expands, after the manner of the peak of a huntsman's cap. 

 The pecuharity is most pronounced at the lower end of this dyke, 

 gradually disappearing 200 yards higher up where the normal 

 form only is found. 



L. truncatula Miill. Kirkleatham ; Coatham Marshes. 



Ancylus fluviatilis Miill. Occurs sparingly in AVest Dyke.
