The Char of Windermere, but probably not the only species 
there. 
Body compressed, slightly elevated; length of the head a 
little more than one half of the distance of the snout and of 
the vertical from the origin of the dorsal fin. Head compressed; 
interorbital space convex, its width being less than twice the 
diameter of the eye. Jaws of the male of equal length 
anteriorly; teeth of moderate strength, four in each intermaxillary, 
twenty in the maxillary. Length of the pectoral fin less than 
that of the head, much more than one half between its root 
and that of the ventral. Nostrils immediately before the eye. 
The maxillary bone (mystache) extends scarcely beyond the 
hindmost margin of the eye; two pairs of teeth on the vomer, 
four pairs on the tongue. Mr. Mascall observed (Loudon’s 
“ Mag. Nat. Hist.,” vol. viii, A.D. 1835,) that in the examples 
he met with, the bones of the gill-membranes were not in 
equal numbers on both sides. Dr. Gunther remarks that 
nearly all these bones are exposed to sight in a side view of 
the fish. The origin of the Dorsal fin is exactly in the 
middle between the snout and root of the caudal; the rays 
twelve in number, the first very short, fourth and fifth longest. 
Anal fin with twelve rays, its origin exactly in the middle 
between the root of the caudal and that of the outer ventral 
ray; the first ray very small, the five first rays obscured by 
being enclosed in a common membrane, the fourth longest, 
fifth branched. Tail fin forked, the lobes pointed; pectoral
