lioad is smooth, liis Ixuly sraly. His dorsal tins arc two in 

 nmnl)cr, the first siiinjortcd by soft rays, the second adipose or 

 fatty, without rnys ; he lins teeth on the vomer, both pahitiiic 

 bones, and all the maxillary bones. His bninchioste<j;ous rays 

 \ arv in number, ^'enerally, from ten to twelve, but arc irrcfrulan 

 and do not al\\ays coincide on the two sides of tin* head. The 

 teeth on tlie vomer rarely exceed two in nuinbi r, and tlu-re is 

 fi-equcntiv l)nt one; a si^ni whieli is thought to di^tinJ;nish him 

 tVom the Salmon Trout, and other connected species. 



The length of his head, to the whole length of his l)ody, is as 

 one to five; tlu- eye small and nearer to the point of the nose 

 than to the posterior cd«;c of the j;ill-cover. The pectoral fin is 

 two-thirds the Icnjjtli of the head, and has tw( Ive fin-rays. The 

 ventral fin lies in a vertical liiu; xmder the middle of the dorsal 

 tin, and has nine rays; the anal fin commences about half-way 

 between the origin of the ventral and caudal fins, and has nine 

 rays; the caudal tin, or tail, has nineteen rays ; when tin- WsU is 

 ver}' young, it is much forked, but as it advances in years, the 

 central caudal niys grow n[); and it becomes nearly s(|uare by 

 the end of the fourth year. The first dorsal fm h.is thirtccMi 

 rays, all of which, with the exception of the two fir.st, are 

 branched. The body is long, and about et|ua]ly couma al)o\e 

 and below; the lateral line dividing the body nearly ecpial, and, 

 to a certain degree, parting the dark hue of the back, and 

 silvery whiteness of the belly. 



The form of the gill-covers, shapes of the fins, and relative 

 proportions of the whole fish, will be readily mnlerstood by 

 reference to the cut nt the head of this article, which will give 

 n more correct iclca than any written description.
