 front of eye, small barbel at tip ; gill-membrane broadly joined to isthmus, 

 branchiostegals 3. Body robust, plump, and rounded in front, somewhat 

 compressed 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 ; ] .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 othei's; 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; fi-om Couesius by the more pointed head and sucker-like appearance; 

 also there are only 7 rays in its anal fin, 8 in Couesius. 



The above is apparently the only distinctive English name for the 

 fish. " Longnose brook minnoAv " 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, cataractce, meaning 

 " of the cataract," the original type being from Niagara Falls. It 

 feeds mainly upon small aquatic animals, such as worms and larvae 

 of insects, also upon insects that fall upon the water. The inferior
