336 SEVENTH REPORT OF THE FOREST, FISH AND GAME COMMISSION. 



The Caledonian specimen has no hyoid teeth ; the vomerines are in a very small 

 patch on the head of the bone only. The gill rakers are 4+ 10, the longest about 

 one-half the diameter of the eye. It has about 124 tubes in the lateral line. 

 Branchiostegals, 10. The following color notes were taken from the fresh fish: 

 Dorsal fin with numerous dark blotches resembling those of young rainbow ; adipose 

 long and slender, amber color with two obscure dusky blotches, one of these very indis- 

 tinct ; lower half of sides pink ; ventral, anal and caudal pink; ventral and anal with 

 a milk white front margin, that in the anal limited behind by a dark line as in Brook 

 Trout ; sides reticulated with large meshes of lemon yellow interspersed with darker 

 purplish or olive. Dorsal blotches are mingled with pale lemon. Pectoral pale 

 vermilion. Eye silvery white with yellowish reflections. 



The specimen from Oakdale, L. I., weighed 20 ounces. It has a triangular patch 

 of vomerine teeth, as found in font inalis, but continued behind by several teeth in 

 a single row, the entire length of the vomerine series being seven-sixteenths of 

 an inch.

Salmo trutta levenensis JORDAN & EVERMANN, Check-List Fish. N. A., 512, 1896. 



The Loch Leven Trout of Great Britain was introduced into the United States 

 from Scotland in 1885 and subsequent years. It is somewhat closely related to the 

 European Brown Trout, Salmo fario, and has been artificially crossed with that 

 species in the United States, so that it is sometimes difficult to find the pure bred 

 Loch Levens in fishcultural establishments at home. 



The body of the Loch Leven is more slender and elongate than that of the 

 Brown Trout, its greatest depth contained four and one-fourth to four and one-half 

 times in the total length without caudal. Caudal peduncle slender, its least depth
