LAND AND FRESH WATER SHELLS OF OXFORD. 20S 



Planorbis spirorbiis. Common, and very similar to the above. The Cherwell, 

 Ac. 



contortus. Amongst Lemna minor. Common. Feny Hinksey, &c. 



Cyclostoma elegans. Stow Wood, by the roadside ; near Eadley school. 



Cyclas rivicola. The Isis and Cherwell ; very fine. Also in other streams. 



cornea. Ponds and ditches, in the mud. Very abundant. 



"-i lacustris. River Ouse, near Buckingham ; but rare. 



Pisidium obtusale. (?) A small species found in a stream near Woodeaton, 

 and also in the Isis, in Port Meadow, I can only refer to this species; though 

 the specimens are smaller than I should have expected to find P. obtusale. 



pusillum. River Isis, above Godstow. Scarce. 



pulclielliim. Ditch at Cowley ; Isis, near Godstow. Rather scarce. 



Henshwianum. Isis, near Godstow. Not rare, though the adult 



shells are rather scarce. It appears to have increased since the introduction 

 of the American Waterweed, (Anaeharis alsinastnim,) amongst which it is 

 found. It was formerly considered very rare in this neighbourhood, and only 

 a few specimens were recorded; but I have found it in tolerable abundance, 

 both in the Isis, and in streams at Ferry Hinksey and Wytham. 



amnicum. Streams at Wytham, Godstow, Ferry Hinksey, &c. 



Anodon cygneus. Common in streams and ditches, but rarely large. Very 

 fine in the Blenheim Lake, and the " Wolvercot railway cutting." 

 Unio tumidus. The Isis and Cherwell. Common. 



Dreissena pohjmorpha. Abundant in the Oxford Canal ; and especially in 

 the Lock, near Worcester Coll. gardens. The Cherwell. On live shells uf 

 A. cygneus, in the " Wolvercot railway cutting." June, 1855.

Another "affair" between a Weasel and a Rabbit. In a stroll, last spring, 

 among the countless thousands of wild flowers, consisting principally of 

 Primroses, Bluebells, and Wood Anemones, with which every open space in 

 Cokethorpe Wood was covered as with a carpet of surpassing richness and 

 beauty, I had just ascended to a Ringdove's nest, which was placed in a 

 Spruce Fir, about fourteen feet from the ground, and was feasting my eyes 

 on the two milk-white eggs the nest contained, or rather which were lying 

 upon the platform of twigs the Columbidse are in the habit of putting to- 

 gether, and having so done, make themselves happy in the conceit that they 

 have really constructed a nest ; and which indeed does answer tlie purpose
