Gobitis. fishes. MALACOPTERYGIOUS. 189

the belly white. D. 8, P. 14, V. 8, A. 8, C. 19, marked at the base with a 
dark spot.— This fish, well known to young anglers, is extensively employed 
as a bait, in the capture of many fresh-water fishes. 
According to Mr Stewart, the Cyprinus Idus of Linne, a species minutely 
described by Artedi, Ich. Disc. p. 6., was found in the mouth of the Nith by 
the late Dr Walker.

Size of the preceding. Body compressed ; above brown, with black spots. 
D. 10, P. 11, V. 7, A. 9, C. 17 — This species was introduced into the Bri- 
tish Fauna by Berkenhout, who, after giving its residence as in lakes or ponds, 
adds, “ also in the Trent.” Turton, in his British Fauna, i. 103, states, that 
it is “ found in the clear streams of Wiltshire vdth the last.” 
At this place it may be proper to notice a remark of Sibbald’s, leading to 
the conclusion that the Silurus Glanis may have occurred in his day in some 
of the Scottish rivers. At the conclusion of his list of river fishes, he adds, 
Silurus, sive Glanis.” — Scotia Illustrata^ p, 25.

latus. Bon. Brit. Fishes, t. Ixvi — Southern coast of England and 
Hebrides. 
Length about 4 inches. Body reddish, with dusky spots. In maturity, 
there are two ocellated marks behind the eyes ; each consisting of a large obo- 
vate spot of a deep purple, inclosed within a broad pale brownish ring, and 
embellished in the centre with a brilliant blue dot. P. 17, A. 10, C. 6. This 
species, found on rocks at low water, differs firom the L. Gouani and L. Balbis 
of Risso. The former of these figured by Gouan, Ich. p. 177- gen. xxxiv. t. 
i. f. 6, 7, differs in the spots behind the eyes being crescent-shaped, and the 
dorsal fin having a greater number of rays.
