 THE LAND AND FRESHWATER MOLLUSCA 



OF 



INGLETON, CLAPHAM, AND DISTRICT. 



W. E. COLLI NGE, 



Leeds; Honorary Assistant Curator to the Conckological Society of 

 Great Britain and Ireland. 



The district round Ingleton and Clapham, wliich I have had 

 numerous opportunities of examining, is one of great interest to the 

 naturahst, and peculiarly favourable to molluscan life. Numerous 

 papers dealing with the geology of this district having previously 

 appeared from the pens of well-known geologists, I have not thought 

 it necessary to preface this list with any remarks on the subject, it 

 being sufficient to note that most of the species recorded have been 

 taken on the Mountain Limestone. 



Previous records have been published in Vol. V. of the ' Journal 

 of Conchology,' by Mr. Hugh Richardson, p. 60; Mr. C H. Pierson, 

 p. 183 ; by myself, p. 197 ; and in Vol. VI, p. 40, by Mr. Edward 

 Collier. Mr. Richardson's paper includes the records of Mr. J. R.. 

 Brockton Tomlin and Mrs. M. C Hughes, and Mr. Collier's includes- 

 those of Messrs. C. Oldham and R. Standen ; to the records of these 

 conchologists, and other observations not my own, I have appended 

 the names of the authorities. 



To my friend Mr. W. Denison Roebuck, F.L.S., my thanks, 

 are due for having kindly placed at my disposal the records of the 

 Conchological Society of Great Britain and Ireland, which include 

 those of Mr. Wm. West, many of which are here published for the 

 first time. 



The ponds mentioned as ' ponds on Clapham Common ' are four, 

 situated about half-way across the Common, and about a mile and a 

 half from Ingleton. I visited these ponds at Easter, 1883-4-7, and 

 once or twice during 1885-6, when they swarmed with fine specimens 

 of Sphjeriidee and Limnaeidce ; visiting them, however, at Easter, 

 1888, I was very much surprised to find an entire absence of any 

 specimens whatever, the reason of which was not far to seek, some 

 enterprising person having erected, in close proximity, a wooden 

 shed for the shelter of a la!^ge flock of fowls, geese and ducks, whose 

 rapacious appetites could no doubt account for the disappearance of 

 the shells. 



The number of species enumerated in this list is 83, and 27 

 varieties. 



April 1890.
