NOTE on YORKSHIRE MOLLUSCA. 



Valvata cristata in Upper Airedale, Yorkshire.— Whilst working 

 the Leeds and Liverpool Canal above the Five Rise Locks, Bingley, for 

 aquatic molluscs, along- with my friend Mr. Fred Booth, I was pleased to 

 find Valvata cristata had made its appearance and was fairly common. 

 This is a new record for Upper Airedale, also for the district under the 

 supervision of the Bradford Naturalist Society, as a living- mollusc ; it has 

 only been previously found in the lake marl in Crummockdale by Hugh 

 Richardson in 1886 (see 'Journal of Conchology,' Vol. 5, p. 61). This shell 

 has certainly been introduced since the publication of Messrs. Carter and 

 Soppitt's 'Land and Freshwater Molluscs of Upper Airedale,' in 'The 

 Naturalist' of March 1888, for this particular place is one that has been most 

 visited by the various collectors mentioned in that list and would certainly 

 have been found if it had been there. — Fred Rhodes, Art Museum, Brad- 

 ford, 20th Aug-ust 1902. 



Cyclostoma at Oxcombe, Line. N. — Four dead specimens of Cyclostoma 



elegans were found by Mr. H. W. Burchnall and the writer on 4th August in 

 Jericho Plantation, Oxcombe, and Farforth Valley, Div. 10 North. — C. S. 

 Carter, 8, Bridge Street, Louth, 14th August 1902. 



Pisidium subtruncatum near Louth, Line. N. — Among the mollusca 

 taken from a large pond, in boulder clay, near Haugham, Div. 8 S., on 

 4th August, was a Pisidium, which I have since submitted to Mr. J. W. 

 Taylor, who says it is rather uncertain, but that he was inclined to refer it 

 to Pisidium subtruncatum of Malm, which is perhaps properly regarded as 

 a form of P. fontinale. Other specimens obtained were : — One P. milium, 

 one Planorbis nautileus, three PI. albus, and several fine examples of 

 Limncea stagnalis. — C. S. Carter, 8, Bridge Street, Louth, 14th Aug. 1902. 



Agriolimax agrestis Devouring Earthworms. — On Saturday, 14th 

 June, when journeying along Horncastle Road, Louth, my attention was 

 attracted to an Agriolimax agrestis apparently devouring an earthworm, 

 the worm being about three inches in length. As I had always thought 

 this slug was exclusively herbivorous, I was in doubt whether it was really 

 devouring- the poor creature, but after watching it through my lens for 

 a little time, I no longer had any doubt, for by this time it had eaten some 

 portion of its victim's posterior end. The worm was in a semi-helpless 

 condition, and made one or two attempts to get away. 



On the next day and on the same road, but about a mile further, I found 

 another devouring a portion of an earthworm. This worm had apparently 

 been crushed to death by some pedestrian, as other portions were lying 

 close by. 



To-day, when looking at some molluscs I have in captivity, I found 

 Hyalinia cellaria devouring Helix rufescens, and it had already disposed of 

 a considerable portion of the Helix. — C. S. Carter, 8, Bridge Street, 

 Louth, 16th June 1902. 



The pith of the Wild Birds Protection Act, 1902, which has just been 

 passed by Parliament, is as follows : — ' Where any person is convicted 

 of an offence against the Wild Birds Protection Acts, 1880 to 1896, the 

 Court may, in addition to any penalty that may therein be imposed, order 

 any wild bird, or wild bird's egg, in respect of which the offence had been 

 committed, to be forfeited and disposed of as the Court shall think fit.' To 

 which we would add an expression of a hope that it will always be strictly 

 enforced, and that any such specimens, if of value, shall be presented to 

 such national or municipal museums as are willing to display it permanently. 

 It would be a pity that useful specimens should be destroyed, while the en- 

 forcement against the offender would g-o far to prevent similar destruction.
