ABDOMINAL MALACOPTERYGIANS. 193 



spotted with hlack and sometimes with red; brownish, longitudinally 

 streaked with blackish; an excellent fish for eating* (a). 



Coregonus, Cvv. 



The Lavarets have the mouth as in the preceding subgenera, and more 

 feebly armed, as it is frequently edentated; scales still larger; length of 

 the dorsal less than the height of its anterior portion. Several very si- 

 milar species are found in Europe ; one of them, however, 



C. oxyrhynchus ; Salmo oxyrhynchus, L. ; Bl. 25, under the false 

 name of Lavaret, the Houting or Hautin of the Belgians, is easily 

 distinguished by a soft prominence at the end of the snout. From 

 the North Sea and the Baltic, where it pursues the Herring. It is 

 also taken in the Scheldt, in the lake of Haarlem, &cf" 



C. marcenula; Salmo marcenida, Bl. 28, f. 3; S. alhvla, Ascan., 

 pi. xxix. (The Vemme). Strongly characterized by the lower jaw, 

 which projects beyond the upper one J. 



The others have an obtuse snout, as if truncated; it is extremely diffi- 

 cult, however, to assign to them precise characters. Such are 



C. marcena; Salmo marcena, Bl. 27- (The Marene). From the 

 lakes of Brandebourg; its snout, although obtuse, extends beyond 

 the mouth. 



C Wartmanni ; Salmo Wartmanni, Bl. 105. (The Waurtmaune, 

 or Lavaret). From the lakes of Bourget, Constance, the Rhine, 

 &c. The snout is truncated even with the front of the mouth, the 

 head is shorter in proportion, and the form longer and more slender. 



C. fera, Jurine, Mem. de la Soc. Phys. of Geneva, III, part I, 

 pi. vii. (The Fera). From the lake of Geneva, and some others; 

 it is higher than the Wartmaune, and has larger fins. 



C. hyemalis, Jurine, lb., pi. viii. (The Gravanche). From the 

 lake of Geneva, where it is found in the winter only ; its head is 

 thicker, and its fins are larger in proportion than in the fera. 



C. palcea, Cuv. (The Black Palsea). From the lake of Neuf-

f The genus Triptekonotus, Lacep., is founded on a had figure of this Houting 

 sent to Rondelet (Rondel. 105), to which, by some mistake, three dorsals had heen 

 given — that genus must consequently he suppressed. The very improper name of 

 Albula nobilis was transferred to it hy Schoenefield, and Linnaeus and Artedi con- 

 founded it with the Coregonus, an example followed by Bloch. The Salmo thymallus 

 latus, Bl. 26, appears to be a variety of it in the spawning season. 



X Add, Salmo elupeoides, Pall. 



ggf (a) The Grayling is one of the most interesting objects of the pursuit of the 

 British angler; because, perhaps, it is a rare fish, and has heen said to have been 

 brought over to this country by the monks in antient times. It has in foreign coun- 

 tries the name of the " flower of fishes" given to it, according to popular tradition by 

 St. Ambrose, on account of its agreeable odour. The angler, in order to take the 

 Grayling, usually employs small flies of the Ephemerae or Phryganeae families: the 

 imitation of a grasshopper is found likewise to be an irresistible bait. — Eng. Ed.
