 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 Idas 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 with the last." 



At this place it may be proper to notice a remark of Sibbald's, leading to 

 the conclusion that the Silurus Giants 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 Jlluslrata, p. 25. 



Gen. XXXV. LEPADOGASTER. Sucker.— Head de- 

 pressed ; body smooth.

Zool. iii. 137 Cyclopterus corn. Shaw, Gen. Zool. v. 397 — Cyc. ocel- 



latus, Don. Brit. Fishes, t. lxvi 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 from 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 i - ays.
