Nineteen Years (Figs. 116, 117, 118). — From in trout the superior 

 corner teeth point distinctly toward the median line; tiie internuMliate 

 teeth commence to incline in the same direction, showing a marked tri- 

 angular space between them at the line of the gums. In profile, the 

 ogive formed by the apposition of the jaws is more closed. The notch 

 still remains in the superior corner teeth, but is less marked in this nge 

 from the increased horizontal position of the inferior corner teeth. The 

 tables of the pinchers and the intermediate inferior teeth seem to con- 

 verge at their posterior border, on account of their diverging in front; 

 their antero-posterior diameters have become greater. The inferior cor- 

 ner teeth are always triangular in the upper jaw ; the pincher teeth are 

 usuall}- leveled, although the cups sometimes remain in them for several 

 3-ears more.
