FITZGERALD : SHELLS OF HARROGATE AND DISTRICT. 23 



informed me that he had taken the var. curta at Plumpton. 

 I have since taken both the type and this variety at the 

 same place. Sub-fossil on banks of the river Tutt at Staveley. 



P. fontinalis var. curta Jeff. — As mentioned above. 



Limneea peregra (Miill.). — A very abundant species all over 

 the district. Lake, Ripley Park (fine); Starbeck Reservoir; 

 Ditch, railway side near Harrogate ; Stagnant pool, Crimple 

 Wood; Ditch, Stone Rings ; Pond, Ribston Park ; Pond nr. 

 AUerton ; Rudding Park ; between Nidd Bridge and Knares- 

 borough; Sewage Farm; Plumpton; Staveley Pond; Ripley 

 Beck ; Ditch near Pannal, Ditch near Killinghall ; near 

 SpofForth. The finest occur in FuUwith Stream. Shaw Mill 

 (F.T.W.) and Hartwith (F.T.W.). Sub-fossil on banks of 

 river Tutt at Staveley. 



L. peregra var. ovata Drap. — Beautiful specimens of this 

 variety occur in Crimple Beck and Ripley Park. 



L. peregra var. acuminata Jeff. — Occurs at Markington. 



L. peregra var. ampullacea Rossm. — Also occurs in Plump- 

 ton Lake. 



L. auricularia (L.). — Local. Exceedingly fine and numerous 

 in the N. E. Rly. Co.'s Reservoir at Starbeck. I obtained 

 one specimen on July 19th 1887 at Staveley Pond; the 

 Rev. E. Ponsonby Knubley has also obtained it from this 

 pond. It occurs sub-fossil on the banks of the river Tutt. 

 Mr. Walker has taken it in the Swinsty reservoir just 

 inside the boundary. 



L. stagnalis (L.). — Local and not numerous. Some of the 

 finest I ever saw I obtained in a small sheet of water in 

 Copgrove Park. The greater portion of this sheet of water 

 is completely overgrown with lilies, rushes, and other water 

 plants, and if steps are not taken to clear away some of the 

 rushes etc., the pond will soon disappear altogether, only 

 leaving a slight inundation to show where it had previously 

 existed. Occurs in a sub-fossil condition on the banks of 

 the Tutt.
