THE FOOD AND GAME FISHES OF NEW YORK. 337 



three-eighths of the greatest depth of the body, and equal to length of snout and 

 eye combined. The head is rather short and conical, its length two-ninths to one- 

 fifth of the total length without caudal. The snout is one-fourth or slightly more 

 than one-fourth as long as the head. The interorbital space is somewhat con- 

 vex, its width equal to three-fifths of the length of postorbital part of head. 

 The eye is of moderate size, its long diameter contained five and one-half to 

 six times in the length of the head, and equaling about twice the greatest 

 width of the maxilla. The maxilla reaches to or slightly beyond the hind 

 margin of the eye. Teeth rather strong, those in the intermaxillary and man- 

 dible the largest, triangular head of vomer with two or three in a transverse 

 series at its base, teeth on the shaft of the vomer usually in a single, partially 

 zigzag, persistent series. Mandible without a hook and little produced even in 

 breeding males. Dorsal origin distant from tip of snout about as far as end of 

 dorsal base from base of caudal ; the dorsal fin higher than long, its base one-eighth 

 of total length without caudal, its longest ray equal to longest ray of anal fin. The 

 anal fin is much higher than long, its distance from the base of the ventral equaling 

 length of the head. The ventral origin is nearly under the middle of the dorsal, 

 the fin being as long as the postorbital part of the head. Pectoral equals length of 

 head without the snout. Adipose fin very small, its width one-half its length, which 

 is about equal to eye. Caudal fin emarginate unless fully extended, when it 

 becomes truncate, the outer rays about one-seventh of total length, including 

 caudal. D. i3( = iv, 9); A. I2( = iii, 9); P. 14; V. 9. Scales 24 to 28 118 to 

 130 26 to 30 ; pyloric caeca 47 to 90 ; vertebrae 56 to 59. 



Upper parts brownish or greenish olive, or sometimes with a reddish tinge, sides 

 silvery with a varying number of x-shaped black spots, or sometimes rounded brown 

 spots or rounded black spots which may be ocellated ; occasionally red spots are 

 seen on the sides, and the adipose fin may have several bright orange spots, or it 

 may show a red edge and several dark spots ; sides of the head with round black 

 spots; dorsal and adipose fins usually with numerous small brown spots; tip of 

 pectoral blackish ; anal and caudal fins unspotted, but the caudal sometimes has an 

 orange margin and the anal a white edge with black at its base ; a similar edge may 

 sometimes be observed on the ventral. 



The Loch Leven Trout is a non-migratory species, inhabiting Loch Leven and 

 other lakes of Southern Scotland and of the North of England. Its range in Great 

 Britain and on the Continent of Europe has been greatly extended by fishcultural 

 operations, and the fish is now fairly well known in the United States, though 



mixed to some extent with the Brown Trout, as remarked above.
