32 FISHES OF THE CONNECTICUT LAKES. 
between tip of snout and upper end of gill-opening; maxillary not reaching 
front of eye, small barbel at tip; gill-membrane broadly joined to isthmus, 
branchiostegals 3. Body robust, plump, and rounded in front, somewhat 
eompressed posteriorly; arched rather abruptly from occiput; lateral line 
nearly straight, about in axis of body; dorsal moderate, inserted about mid- 
way between tip of snout and base of caudal, first rays longest, 1.57 in head, 
scarcely extending beyond tip of last rays when depressed; first anal rays 
extending slightly beyond last when depressed; 1.57 in head; pectorals short, 
1.4 in head, inserted low, about on level with mouth; ventral short and some- 
what rounded, or with rounded angles, and inserted somewhat in advance of 
insertion of dorsal; scarcely reaching vent; caudal forked. 
Described from a female example 4.54 inches in length, from Round Pond 
Brook August 12. 
Seven specimens from this locality ranged in length from 1.54 to 4.54 inches, 
averaging 3.30 inches. Head in length without caudal ranged from 3.9 to 4.33, 
averaging 4.11; depth 4.22 to 5.60, averaging 4.11; eye in head 4.2 to 6.28, 
averaging 5.39; snout 2.14 to 2.85, averaging 2.51; interorbital 3.14 to 3.50, 
averaging 3.31; scales 59 to 66, averaging 64; dorsal rays 8, the longest ranging 
from 1.28 to 1.57 in head, averaging 1.36; anal rays 7, the longest ranging from 
1.30 to 1.57 in head, averaging 1.47; pectoral ranging from 1.20 to 1.45, aver- 
aging 1.34 in head. 
Upper part of head, back, and sides bluish gray, much speckled with brown 
or darker gray, more intense on some scales than others; maxillary, chin, throat, 
and belly white; dark speckling often grouped, giving a mottled appearance, 
and so intense on side, especially posteriorly, as to make a more or less definite 
lateral dusky stripe. Males in spring with more or less crimson, especially on 
the lower fins. 
Distinguished from the other species by the longer, more projecting snout 
and lacking the distinct jet black lateral stripe of the other; and from all other 
minnows in this region except the chub minnow by the inferior position of the 
mouth; from Couwesius by the more pointed head and sucker-like appearance; 
also there are only 7 rays in its anal fin, 8 in Cowesius. 
The above is apparently the only distinctive English name for the 
fish. ‘“ Longnose brook minnow ” or “ rock minnow ” may be sug- 
gested. 
As previously stated, this species has not before, to our knowledge, 
been definitely recorded from New Hampshire. Jordan and Ever- 
mann give its range as “ New England to Virginia and Wisconsin; 
its varieties ranging to Utah and the Columbia basin.” It was col- 
lected by us in the following places: First Connecticut Lake in 
mouth of Mud Pond Brook, tributary brook of Main Inlet, Alder 
Brook, Round Pond Brook, Outlet Third Lake, and Indian Stream. 
This minnow is said to attain a length of 5 inches. Our specimens 
range from 1.25 to 4.54 inches in length. 
The favorite habitat of this species is clear rocky brooks and 
streams. Jordan and Evermann say that it frequents clear and bois- 
terous streams and rock pools, the specific name, cataractw, meaning 
“of the cataract,” the original type being from Niagara Falls. It 
feeds mainly upon small aquatic animals, such as worms and larvee 
of insects, also upon insects that fall upon the water. The inferior
