the mouth is closrd, projects beyond the upper one by the 

 ilcpth of the ehin, and it appears h)n^er yet when the month 

 is open. 



The teeth of the hibials, interniavilhirit'^, and lower jaw, arc 

 very small, short, conical, acute, and slij^htly curved — on the 

 palatine bones there is a row of lar^'cr teeth mixed with smaller 

 ones, and on the knob of tlu' vomer, a cluster of six or seven. 

 The tongue is anni-d with a single row on each sicU-, which meet 

 in a curve at thi" ti[) ; then' arc also two or three scattered teeth 

 on the centre of the tongue. The rakers and i>haryni;cal bones

 scarcely ludf its hciglit. The suh-ojjrrcnhtm exceeds tlie half of 

 its length in height. 



The Masamacush of the Mingan Kiver, which is the tish in 

 its normal form, according to Dr. Richardson, from wJiom this 

 account is abridged, has ten gill-rays on one side, eleven on the 

 other; dorsal tin-rays twi-lvt-, pectorals thirteen, vcntrals eight, 

 anal ten, and caudal nineteen. 



The back and sides of this tish are intermediate between olive 

 green and clove broun, bestudded \\\\\\ yi'llo\\i>h grey spots aa 

 big as a pea. A few of these spots on the gill-covers, Helly 

 and under jaw white; the latter dotted thinly with bluish grey. 



The Arctic fish is brighter in colour ; the i)ack and sides 

 being purple, the spots distinctly yellow, and the sides, below 

 the latcnil line, tinged with a flush of lake. 



IJcforc proceeding to the Grayling, which, though of this 

 family, is not a pro|>cr Salmon, but of the subgenus Thytmilhts,
