38 A CORNISH FAUNA. 



mackarel, I can say with confidence that the fish described 

 in British Fishes as " dotted " and " scribbled" mackarel 

 are accidental varieties.* 

 Spanish Mackarel. (Scomber maculatus). I am very doubtful 

 also whether this is a distinct species. Its variation from 

 the typical fish does not appear to me to be sufficient to dis- 

 tinguish it. 



Tunny. (Thynnus vulgaris). Not uncommon as a spring and 



summer visitor, but not often taken. 

 Bonito. (Scomber pelamis). Same. 



Grermon. ( Orcynus alalonga). Longfinned Tunny. Very rare. 

 Pelamid. (Pelamis sardaj. Belted Bonito. I take this to be a 



fish known to mackarel fishermen as the albacore, and if so 



it is common in spring and summer. 

 Plain Bonito. (Auxis vulgaris). Rare. A specimen has been 



recently (1877) taken in Mount's Bay. 

 Shortfinned Tunny. (Thynnus brachypterus). Yery rare. 

 Pilot Pish. (Naucrates ductor). Not an uncommon visitor. 



Frequently follows vessels into our harbours. 

 John Doree. (Zeus faber). Common. 



Blackfish. (Centrolophus pompilus ; Cory phcena pompilus). Pare. 

 Has been usually taken in company with a shark or some 

 other large fish. 



Cornish Centropholus. (C. Britannicus). A specimen was 

 thrown on shore near Looe in February, 1859. 



Ausonia Cuvieri. A single specimen was taken at Falmouth in 

 1866. It is supposed to have occurred twice only in British 

 seas. 



Oj)ah. (Lampris Luna). This beautiful fish is but rarely seen. 



Scad. (Trachurus vulgaris). Horse mackarel. Common. 



Derbio. (Centronotus binotatus). A Mediterranean species, of 

 which one example occurred in Mount's Bay, in 1857. 



Boar fish. (Zeus aper). Yery common near the Pundle-stone 

 and Wolf Eocks. In 1 875 large shoals were thrown on 

 shore at Scilly in a gale of wind. It has also occurred 

 singly at Scilly and Whitesand Bay in Sennen. Elsewhere 

 it is rare. 



Sword fish. (Xiphias gladius). Occurs commonly, but is rarely 

 taken.
