NOTES ON SOME FRESH-WATER FISHES FROM MAINE. 
357 
Fish Brook, a tributary of the east branch of the Penobscot River about a mile below Matagamon 
Lake, in Second or Matagamonsis Lake in October, 1900; in these same places and in a small pond 
near Hale Pond, West Branch of the Penobscot, in August; Smith Brook, outlet of Haymock Lake, a 
tributary of Eagle Lake of Allagash River, in September, and Cross Lake Thoroughfare, Aroostook 
County, in October, 1901. In September, 1902, it was obtained by the same collectors in Lunkasoos 
Lake, which empties into the east branch of the Penobscot. 
This is a beautiful little minnow. The small examples are not easily distinguished by color from 
Chrosomtus erythrogaster, which usually occurs with it. An examination of the pharyngeal teeth, 
however, will quickly decide the matter, Chrosomus having but a single row on each bone, while the 
other has a double row. Some differences occur in the Maine specimens from those from farther 
west, to which, though not to separate them as distinct species, it is desirable to call attention. These 
will be shown in the accompanying table, from which it will be seen that there is considerable varia- 
tion amongst them. Cox mentions still more in New Brunswick specimens. 
The writer was privileged to examine some of the New Brunswick specimens, which were consid- 
erably deeper and more “stubby” fish than any of ours, with very steep foreheads and exceedingly 
projecting lower jaws. These were doubtless breeding males. Some of our specimens indicate the 
same form but to a lesser degree. This seems to be the first record of this species from Maine.
