In young specimens, the gill cover overlaps the root of the pectoral; not in 
adults. There are spots on the dorsal fin, and attention should be called to a 
post-ventral dermal appendage. 
Such differences in individuals from the same locality 
would seem to impair the value of anatomical peculiarities 
as diagnostic marks. In fact, ina most able paper on the 
Saiblings, published in the American Angler, February 
7, 1891, and Shooting and Fishing, February 12, Prof. 
Garman states that in foreign specimens examined by him 
the dentition differs, corresponding more or less nearly 
with that of the New Hampshire fish—that differences of 
age imply radical differences in teeth, fins, stomach, and 
especially gill-rakers—which latter Prof. Garman believes
