394 Mr. H. Denny's Sketch of the Natural History 



Leuciscus Erythrophthalmus. Local. I know of only one locality 

 (Campsall), which is rather beyond our distance. 



alburnus. Local. Cawood, Tadcaster. 



Phoxinus. Common. 



Cobitis barbatula. Common. 



Esox Lucius. Common. 



Salmo Fario. Plentiful in the Wharf at Harewood, Bolton, &c. 



Salar. Not uncommon. Cawood. 



Osmerus Eperlanus. Occasionally plentiful. Cawood, Selby. On the 

 21st Dec. 1834, they were in such abundance that they were 

 sold in Leeds market at twopence per pound. 



Thymallus vulgaris. Rather local. Harewood, Bolton, Wakefield. 



Clupea Harengus. I obtained a single example in 1834, taken at Ca- 

 wood. 



■ alosa. I purchased a specimen of this fish in the market for our 

 Museum, which was said to have been taken at Tadcaster. 



Lota vulgaris. Not uncommon near Selby. 



Platessa limanda. Occasionally at Cawood. 



Apodes. 

 Anguilla acutirostris, latirostris. Tolerably plentiful. 



Cartilaginei. 



Acipenser latirostris. This appears to be the only species we have, 



which generally occurs every year at Cawood. Three or four 



fine fish were caught this summer, two of which were brought 



to Leeds alive. 



Cyclostoma. 



Petromyzon fluviatilis. Occasionally. Killingbeck. 



Before closing this sketch of the zoological localities of the 

 neighbourhood, one spot must not be passed over without a 

 few remarks, since the facilities which are there afforded for 

 observing a variety of animals in a state of uncontrolled free- 

 dom are exceedingly valuable. Many interesting facts re- 

 garding the habits of the feathered tribes especially frequent- 

 ing this spot have already been given to the world by the se- 

 cond White of Selbourne (as he has been emphatically termed) 

 who owns the estate. This tract it will readily be perceived 

 is Walton Park, near Wakefield, which owing to its construc- 

 tion, containing 260 acres of wood and meadow, and 24 acres 

 of water, surrounded by a wall from 9 to 10 feet high, forms 

 a rendezvous for all comers and goers of every tribe, terres-
