LAND AND FRESHWATER MOLLUSCA. 327 



mixture of winter and summer fowl on the Broad, a pair of 

 Golden-eyes and fifteen Tufted Ducks appearing with a male 

 Shoveller and a Garganey, ten Common Teal, twenty Duck and 

 Mallard, and a flock of Wigeon, the latter all male birds but two. 

 Shovellers were seen on Bre}'don, again, as early as the 1st of 

 August, and several lots of this species appeared there on the 

 20th, with a few Sheldrakes. I have several notes of Gadwalls 

 killed, both on the coast and inland, in September and October, 

 but as these birds breed in such large numbers upon the meres 

 of the Merton and Wretham estates, and in many localities in 

 West Norfolk along the valley of the Nar, and disperse in 

 autumn, it is impossible now to distinguish foreign arrivals.* An 

 immature Long-tailed Duck, a female, was shot near Yarmouth 

 on the 22nd of October, an early date for this species ; and a 

 few immature Red-throated Divers were shot both in October 

 and November. In December a female Golden-eye on Breydon, 

 with a few Pintail Ducks and flocks of Scoters at sea complete 

 my notes. 



THE LAND AND FRESHWATER MOLLUSCA IN THE 

 VICINITY OF OXFORD. 

 By S. Spencer Peaece, BA. 



This list, the result of conchological rambles during the last 

 three years, is not to be considered as exhaustive, but rather as 

 supplementary to Mr. T. F. Whiteaves' excellent paper " On the 

 Land and Freshwater Mollusca inhabiting the neighbourhood of 

 Oxford," published in 1857, by the Ashmolean Society. Though 

 my rambles have rarely extended for more than six or seven 

 miles around Oxford, this district has yielded more than an 

 average number of species, which I have no doubt might be 

 considerably augmented by further research, for the geological 

 features of the neighbourhood are extremely favourable for mol- 

 luscan life, owing to the extensive exposure of some of the oolitic 

 limestones. 



* Sir E. P. Gallwey, in a most interesting article in ' The Field' of May 

 12th, 1883, on " Fish and Fowl in "West Norfolk," as observed on Lord 

 "Walsingham's estate at Merton, states that the number of Gadwalls on one 

 private water alone was computed at fourteen or fifteen hundred.
