Amphipeplea glutinosa at Tetney, Lincolnshire. — Amphi- 

 peplea glutinosa has once been recorded for Lincolnshire, namely, 

 in 'The Naturalist,' 1S94, p. 68, where mention is made of 

 a sing-le specimen found floating- seawards with the water of the 

 Mar Dyke at Saltfleetby All Saints. The object of the present 

 note is to record the existence of a considerable assemblage of 

 this curious and beautiful Pulmonate at Tetney, where it was 

 found by Mr. C. S. Carter and the writer on 17th April 1902. 

 It occurred in a drain of good size by the left of the road 

 running from the village to the lock (by the right of the road at 

 this place is the great Tetney Drain) ; here it was creeping on 

 the mud in good numbers, and was far more plentiful than 

 Limnaa pereger, L. stagnalis, etc., which occurred with it. In 

 July of the same year, when the locality was visited by Mr. 

 Carter and Mr. G. K. Gude, F.Z.S., only two or three young- 

 individuals and a few dead shells were found ; and fears were 

 entertained as to the permanence of the colony. In April last, 

 however, when Mr. Carter, Mr. Roebuck, and the writer were 

 at Tetney, the animal was again found in all its former 

 abundance, in various stages of growth, and inhabiting the 

 drain as before for a distance of about 150 yards. Among the 

 plants of the place is the curious Bladderwort [Utricularia 

 vulgaris), and in summer the proud heads of Butoiiiiis umbellatiis 

 stand high above the water. — H. Wallis Kew, London, 25th 

 May 1903. 



Sphserium corneum on the Toes of Toads.— On 17th April 

 1902, the day of the finding of Amphipeplea as above noted, 

 Toads were plentiful in the drains at Tetney ; and we secured 

 five, to the toes of the hind feet of which individuals of Sphceritim 

 corneum were firmly affixed. Four carried one shell each, while 

 the fifth, a small toad, had two full-sized shells on the toes of 

 the same foot. The molluscs — conspicuous in this position 

 through the clear water on a dark bottom — were clinging with 

 great tenacity, as usual in such cases, by closure of the valves 

 of the shell, between which no doubt the toads had accidentally 

 intruded their toes. Occurrences of this kind, as the reader 

 will probably remember, have several times been recorded, this 

 same Sphceriiun corneu7n having been found attached not only 

 to the toes of Toads, but also to those of Frogs, Newts, a 

 Snipe, the Great Water-Beetle {Dytiscus), the Water-Scorpion 

 [Nepa], and the larva of a Dragon Fly. — H. Wallis Kew, 

 London, 25th May 1903.
