toothed, and reaches the line of the posterior margin of the pupil. The 
pectoral measures half the distance to the base of the ventral. There 
are five specimens of this fish, which measure about four inches in length, 
and they are stated in the accompanying notes to be of medium size. The 
colors, like those of 0. spectrum, are darker than those of 0. viridescens, 
in spirits. The median line above is dusted with black, and the lateral 
scales, in several specimens, bordered with the same. Fins blackish, es- 
pecially the base of the caudal. From Cobessicontic Lake, in Kennebec 
Co., in Southwest Maine. 
According to Commissioner Atkins, this species spawns immediately 
after the ice disappears, and instead of running into swift brooks, like the 
varieties of O. viridescens, hereinafter described, lays its eggs on the bor- 
ders of meadows. The specimens described were taken in breeding con- 
dition at the breeding season. 
As I owe the opportunity of describing these interesting Osmeri to 
my friend Dr. C. C. Abbott, I dedicate the present species to him.

Two localities furnish specimens of land locked smelt, which I can only | 
distinguish from those of salt water by color. The first from. Lake Mes- 
salonskee, Kennebec Co., have a yellowish color on the sides, and black 
dorsal line, top of head, chin, and edges of lateral scales, The specimen is 
14 inches long, said to be of medium size, therefore exceeding the average 
of the O. viridescens seen in Philadelphia market, and considerably larger 
than the O. abbotti and O. spectrum. They are called the Belgrade 
smelt. , 
Commissioner Atkins states that between the 10th and 20th of April, 
while the lakes are still covered with ice, this fish runs up into the brooks 
and lays its eggs by night, the eggs adhering to grass and stones. The 
spawning is complete always before the ice breaks up in the lakes. The 
temperature of the brooks is from 32° to 40° Fahr. 
The second locality is Cochnewagn Pond, Kennebec Co. Specimens of 
‘‘medium size”’ are smaller than the sea smelt from the mouth of the 
Kennebec, and larger than those of 0. abbotté?. They are generally simi- 
lar to the last variety. These the notes state, breed later by 25 days than 
the last ; that is 12 or 15 days after the ice disappears, the temperature of 
the water being 43° to 45°. 
The breeding season of the O. abbottii intervenes between those of the 
above varieties. 
Commissioner Atkins says that the majority of the lakes of Maine con- 
tain smelt of some kind, and that he frequently finds smelt in fhe stomachs 
of trout from these lakes,
