TABLES OF MEASUREMENTS AND COUNTS ON SPECIMENS OF FISHES FROM RANGELEY 



LAKES WATERS AND VICINITY. 



Tables I to IV and X and XI comprise certain proportional measurements and 

 counts of fin rays, scales, and other structures. Only the extremes of measurements 

 and the averages are given. The proportions are obtained by dividing the length of 

 one part by another. For example: Head in length without caudal, means length of 

 head from tip of snout to posterior margin of opercle into length of fish to base of 

 of the caudal fin. Eye in head refers to the quotient obtained by dividing the length 

 of the head by length of eye, etc. Scales, as 20-107-15, means that there are 20 

 scales, counting the oblique series from the front of the dorsal to and including the 

 lateral line; 107 from the upper angle of the opercle to the last fully developed 

 scale at base of caudal; and 15 scales from oblique series from lateral line to base of 

 ventral. Pharyngeal teeth 2, 4-4, 2, signifies 2 rows of the designated number of teeth 

 on each side, 4 in the major and 2 in the minor row. Spines in fins are indicated by 

 roman and rays by common numerals, the small letter "i" indicating simple, undi- 

 vided, or rudimentary rays. 



Tables V to IX, inclusive, comprise the actual measurements in millimeters. The 

 distance from tip of snout to base of caudal is also given, so that any system of working 

 out the proportions may be employed. The terms employed are practically the same 

 as in the other tables. The figures indicating the gill rakers give the numbers on each 

 arm of the gill arch and the total.
