NATURAL HISTORY OF 
_SAWLEY AND EAVESTONE, NEAR RIPON. 
(Continued from page 208). 
Mo.itusca.—Mr. W. Denison Roebuck, F.L.S., writes that 
the conchologists explored Picking Gill and other parts of 
Sawley parish, the main part of the collections made being by 
Mr. Greevz Fysher that day and about Risplith the next. 
These notes include the mollusca which were collected by Mr. 
James Ingleby in the parish of Eavestone during the years 1882 
to 1886 inclusive, and seen by Mr. J. W. Taylor and himself. 
As Mr. Ingleby pointed out, the district with its peaty soils on a 
millstone grit formation, is singularly unfavourable for mollusca. 
Limax maximus and var. cellavia. Eavestone. 
Agriolimax agrestis and var. reticulata. Abundant at Eavestone, 
Sawley, Picking Gill, Risphth, and Howhill Fountains.. 
A.levis. Eavestone. 
Arion atey. Eavestone, Sawley and Risplith ; var. luteopallescens 
common at the two latter places. 
A, subfuscus. Eavestone and Sawley ; vars. rufofusca and cinereo- 
fusca at the latter place. 
A. hovtensis. Eavestone. 
A. civcumscriptus. Not uncommon, Eavestone, Sawley, Risplith. 
One at Howhill Fountains (Fysher). 
A. intermedius and var. grisea. Sawley and Risplith. 
Vitvina pellucida. Eavestone and Risplith. 
Hyalinia cellavia. Common at Eavestone. 
H. alliavia. A few at Eavestone and Sawley. 
H. nitidula. Eavestone, a few. 
H. crystallina. A small colony in a damp place among trees at 
Eavestone ; a few at Sawley. 
Pyvamidula votundata. Found in Fishpond Wood, Eavestone, not 
very common ; common in Sawley parish. 
Helix nemoralis. Eavestone, not very common. 
H. hortensis var. lutea 12345. Eavestone, very rare. 
Hygromia hispida. Picking Gill, one or two, fine. 
Ena obscura. Stephenson Bank, Risplith, on a wall, very rare 
(Ingleby). 
Claustlia bidentata and var. albinos. On old wall by roadside, 
Lodge Bank (another name for Stephenson Bank), Risplith 
(Ingleby). 
Cochlicopa lubrica. On tiles at Eavestone, not very common ; 
a few at Sawley. 
The only water-shells are those noted by Mr. James Ingleby 
as follows :— 
Pisidium fontinale. Common, taken from the side of a trout pond 
at Eavestone, a few days after the water had broken through 
the bank. The pond had been previously searched several 
times but nothing could be found there, but 
Ancvylus fluviatilis, and that rarely. 
Pisidium pusillum and 
Limnea truncatula were numerous in a ditch fed by a spring at 
Eavestone, quite isolated from any other water. In summer 
the water of this ditch is often dried up, and the ditch was 
often scoured, and how the mollusca lived and multiplied 
was a mystery to Mr. Ingleby.
