 D. 18, P. 12, V. 11, A. 11, C. 19. The second ray of the pectorals strong 

 and produced. At certain seasons said to smell like thyme. Leaves the sea 

 early in spring, and ascends clear and rapid streams to spawn ; returning 

 again before winter. According to Mr Low, (Ork. 224.) " This species is 

 found very frequent with us ; caught with a fly, to which it rises very freely, 

 and struggles hard for life. Swims very quick ; leaps much, especially when 

 struck with a hook."

Before concluding this enumeration of the British Sahnonidse, the fish 

 which Pennant has referred to the Linnean genus Argentina, under the title 

 Sheppy Argentine, requires to be noticed. It is thus described, " A little 

 fish, which I beUeve to be of this species, was brought to me, in 1769, taken 

 in the sea near Douming. The length was 2\ mches ; the eyes large; the iri- 

 des silvery. The lower jaw sloped much ; teeth small. The body compressed, 

 and of an equal depth almost to the anal fin. The tail forked. The back 

 was of a dusky green. The sides and covers of the gills as if plated with sil- 

 ver. The lateral line was in the middle, and quite straight. On each side 

 of the belly was a row of circular punctures : above them another, which 

 ceased near the vent." — Brit. Zool. iii. 327- The Ileverend jNIr Low refers 

 to a fish which he considers as similar to the one described by|Pennant, 

 which was once brought to him in Orkne}'. " It was not above an mch in 

 length ; seemed very delicate ; the colours good ; the back greenish, spotted 

 with darker clouds ; the belly a fine silver ; but it lost all its fine colours 

 when kept dry. All the fins were soft ; and the tail-membrane, as well as 

 those of the other fins, was very thin." — Ork. 225. The fish referred to by 

 Pennant is regarded by Cuvier (Regne Animal, ii. 169), as belonging to his 

 genus ScoPELUS, which difiers from Argentina in tlie mouth and gill-opening 

 being larger, and in the tongue and palate being smooth. He considers it, 

 and with some probability, as identical with S. Humboldti, the Serpe Hum- 

 boldt of Risso, Ich. 358. tab. x. f. 38.
