The only specimen I have met with of this beau- 
tiful little species, which is neither mentioned by 
Mitchell in his “ Fishes of New York," nor by Rich- 
ardson in his * Fauna. Boreali- Americana," was 
brought from Nahant, by Mr. Jonathan Johnson, of 
that place. He found it in December, 1837, alive 
on the beach ; he had never seen a living specimen 
before, but had repeatedly found partially decom- 
posed specimens in the stomachs of haddock. 
The entire length of my specimen is two inches 
one line: length of the head, three lines. The back, 
to the depth of about a line, is of a dark green 
color; the sides, including the gill-covers, are of à 
beautiful silvery lustre. A row of brilliant circular 
metallic colored spots runs along the belly, from be- 
fore. the pectorals to the anus; higher up, on the 
sides, another row of dots parallel with these ; behind 
the anus a single row of smaller dots of a similar 
character, is continued to the base of the tail. Body 
very much compressed. The /ateral line almost im- 
perceptible, nearly straight, commences at the upper 
third of the operculum. Mouth widely cleft; teeth 
small in both jaws. Eyes large, one and a half line 
in diameter ; irides silvery. 
. The fin rays are: . D. 10; P17; _V. 8; A. 15; 
C. 19.
