222 FOREST LIFE IN ACADIE. 



one quarter from tip of nose 'to insertion of tail. The 

 outline rounds up rather suddenly from a small and 

 arched head to insertion of dorsal ; slopes quickly but 

 gently to adipose fin ; then runs straight to insertion 

 of caudal ; tail gently curved rather than cleft ; lower 

 line straight to anal, then falling rather rapidly to make 

 a very convex line for belly, and ending at the gills. 

 The body deeper and more compressed than in the 

 brook trout. The dorsal is quadrangular ; the free edge 

 convex ; the lower fins having the first rays in each 

 thicker and flatter than the brook trout. The adipose 

 fin varies, some with very long and arched free end, in 

 others small and straight. The specimen from the fresh 

 water was very much longer and thinner, with head 

 •proportionally larger. The colour of those from the 

 tide- way was more or less dark greenish blue on back 

 shading to ash blue and white below, lips edged with 

 dusky. They all had faint cream-coloured spots, both 

 above and below the lateral line. With one exception, 

 they all had vermilion specs, but some only on one side, 

 others two or three. In all, the head was greenish horn 

 colour. The colour of the fins in pectoral, ventral, and 

 anal, varied from pale white, bluish-white, to pale 

 orange, with a dusky streak on difi'erent individuals. 

 Dorsal dusky with faint spots, and caudal with dusky 

 tips — ^on some a little orange wash. The lower fins had 

 the first ray flat, and white edged with dusky. In the 

 specimen taken on September the 10th from the fresh 

 water, the blue and silver had disappeared, and dingy 

 ash colour had spread down below the lateral line ; the 

 greenish horn colour had spread itself over the whole 

 gills except the chin, which was white. The silvery
