KENDALL; NEW ENGLAND CHARES. 
The colors are generally olive green above shading into the silvery opalescent of the side 
and white of the belly; the dorsal is somewhat barred but the caudal shows scarcely any bars 
but merely dark marginal shades. The spots of the side are fewer than in the large specimen, 
usually wholly absent or only one or two present. 
Compared with S. fontinalis of about the same size, aside from the coloration and the more 
slender form, the diagnostic differences are few. The vertical fins are lower and the base of 
the dorsal somewhat shorter; the eye is considerably larger and the maxillary longer. The 
gill-rakers are degenerated to a greater degree than in S. oquassa, in which the same tendency 
has been observed. 
Description drawn from a specimen 7^ inches long taken on the night of October 29, 1912. 
Diagnosis. — Head shorter than in S. fontinalis, longer than in S. aureolus, much like S. 
oquassa but somewhat longer. 
Dorsal lower than in S. fontinalis, higher than in S. aureolus, close to S. oquassa. 
Pectoral much shorter than in S. fontinalis, a little shorter than in S. aureolus, close to S. 
oquassa. 
Ventral much shorter than in S. fontinalis, shorter than in S. aureolus, close to S. oquassa. 
Longest anal ray much shorter than in S. fontinalis, longer than in S. aureolus, close to 
S. oquassa. 
Distance from adipose fin to base of caudal greater than in 8. fontinalis, exactly as in S. 
aureolus, little greater than in S. oquassa. 
Distance from anal fin to caudal much greater than in S. fontinalis, less than in N. aureolus, 
ittle greater than in S. oquassa. 
Eye compared with head about the same as in S. fontinalis, larger than in S. aureolus, 
somewhat larger but near S. oquassa. 
Snout a little shorter than in S. fontinalis, close to *S. aureolus, longer than in S. oquassa. 
Length of maxillary close to S. fontinalis, longer than in S. aureolus, and much longer than 
in S. oquassa. 
Mandible shorter than in S. fontinalis, somewhat longer than in S. aureolus and much 
longer than in S. oquassa. 
Dark markings on dorsal and caudal much like S. fontinalis, ocellated red spots on sides 
much like S. fontinalis but very much fewer. Rest of coloration much like S. aureolus but 
lighter. 
Notwithstanding the absence of prominent structural differences, it is a question if it is 
not well to recognize as specific slight differences of that kind in connection with size, shape, 
color, and habits, at least locally constant and fixed. In this case there are no intergrading forms 
and while it shows relationship to S. fontinalis its most pronounced affinities seem to be with 
the Saibling group otherwise than in the apparent absence of basibranchial teeth.
