out the ciuulal. In tlic t.iblc of measurements a larger specimen — ex- 

 treme length, 11 indies — is introduced by way of comparison. 



The type of the description, No. 39334, was obtained in Sunapee Lake, 

 New Hampshire, in the fall of 1887 by Dr. John D. Quackenbos. 



The length of the specimen to the caudal base is G.4 inches. 



The greatest height of the body equals the length of the head, and 

 is contained about four times in the total without caudal. The least 

 height of the tail equals one-third the length of the head. 



The nmxilla reaches past the middle, but not to the end of the eye; 

 its length is contained about two and two-thirds times in length of head. 

 The length of the upper jaw is contained about two and one-third times 

 in the length of the head, and is equal to the longest anal rnj. The eye 

 is a little longer than the snout, and is contained four and two-seventh 

 times in the length of the head. Hyoid teeth well developed. 



The first dorsal is a little nearer the tip of snout than to the base of 

 caudal, and the length of its base is one-half the length of the head. 



The adipose dorsal is distant from end of first dorsal a space equal to 

 twice the length of the ventral. 



The anal is at a distance from the snout equal to about three times 

 tjje length of the head. The longest anal ray is equal to the length of 

 the upper jaw. 



The length of the middle caudal rays are equal to twice the diameter 

 of the eye. 



The ventral is situated midway between the tip of the snout and cau. 

 dal base; its length equals one-half the length of the head. 



The length of the pectoral is about twice the width of the interorbital 

 area. 



B. 10; D. iv, 9; A. iii, 8; P. 13; V. 9; scales 35-210-40; gill-rakers 

 G+ 10-12. 



The peculiarity of the gill-rakers of this trout is that they are always 

 curled up at the ends and not straight, as in the oquassa from Maine. 



Colors. — Sides silvery white. Back with about six well-defined 

 baud like markings, besides some irregular dark blotches. There are 

 about ten parr marks on the sides, and numerous small, roundish, white 

 si)ots. In colors this char is different from the oquassa from Maine, but 

 if fresh specimens of the Maine trout were compared with this young 

 fish the difference in color might not be so great. 



The specimen described is a young male with the spermaries showing 

 as a mere slight ribbon ; its stomach contained an earth-worm and the 

 wing-cases of a squash-beetle. The other two specimens (somewhat 

 smaller) are females far from maturity. 



In a female, No. 37408, 11 inches in total length, both parr marks and 

 bauds across the back show very plainly. This female has a few free 

 eggs in the abdominal cavity and seems to be nearly spent. In examples 

 of this size the tail is deeply forked, the middle rays being less than 

 one-half as long as the external rays. 



In males the pectoral is always longer than iu females of equal size.
