FISHES. 129 
Salmo grayi Géxth. Gray’s Charr. 
Salmo colii Giinth. Cole’s Charr. 
Osmerus eperlanus (Z.). Smelt. 
Resident and common in the estuaries of the Tees and 
Humber. It abounds in the Ouse and the Humber from 
Naburn Lock to Spurn Point, and occurs a considerable 
distance up the Tees. Yarrell states that Col. Meynell, of 
Yarm, kept Smelts for four years in a freshwater pond 
having no communication with the sea, where they con- 
tinued to thrive and propagated abundantly. When the 
pond was drawn, the fishermen of the Tees considered 
that they had never seen a finer lot of Smelts ; there being 
no loss of flavour or quality. 
Coregonus clupeoides Zap. Gwyniad. Powan. 
Coregonus vandesius ich. Wendace. 
. Coregonus pollan Zhiomp. Pollan. 
. Thymallus vulgaris JVi?ss. Grayling. 
Freshwater resident, found in varying abundance in the 
middle waters of the Wharfe, Washburn, Nidd, Ure, and 
Swale, also in the Cover, Wiske, and Codbeck, the Rye 
and other tributaries of the Upper Derwent, and in the 
Scalby Beck near Scarborough. In the Tees it is very 
limited in its numbers, and it has been introduced into the 
Esk. Formerly abundant in the Ribble and Hodder, 
their extreme scarcity—if not extinction—being ascribed 
to the great increase of Salmon. It was also formerly 
abundant in the Aire about Bingley, but in 1824 all were 
destroyed by the bursting of a peat bog; subsequent 
attempts at re-introduction have as yet proved ineffectual. 
. Argentina silus (Ascanius). 
. Argentina sphyreena Z. Hebridal Argentine. 
Extremely rare, there being only one record for the county.
