Lac, which attains in N'ew Brunswick a len2:th of 

 eighteen inches. Tlie llatter and longer head and snout, 

 broad rosy band, coarsely tuberculate lips, and minute 

 scales, distinguish it readily from the common species, 

 especially in the breeding season. 



Very little is known definitely of the movements of 

 this fish. From what the writer observed and could 

 learn from settlers and Indians, it seems to prefer in 

 summer cold, rapid streams and the deep waters of lakes, 

 being in this respect very unlike the common variety, 

 which finds a congenial home on the gravelly and mudd}^ 

 bottoms of even sluggish streams. In June large speci- 

 mens are said to be quite common, moving up the 

 thoroughfares of lakes in company with the spotted 

 trout ; but their summer habitat is not well known. 

 The immature fish seem to frequent, in summer, lakes 

 and the lower stretches of rivers, at least many are found 

 in such places. As the writer has pointed out a corre- 

 spondence between the fish faunas of the St. John and 

 Restigouche {vide Bulletin No. XI. iSTatural History 

 Society, St. John), the long-nosed sucker will likely be 

 found in the latter river. 



Gasterosteus inconstans Kirtland. Brook Stickleback. 

 Five-spined Stickleback. 



This species was first reported a few years ago b}^ the 

 writer. It is very rare in the northern parts of the 

 province, where its place is taken by G. ■puiigitius^ L., 

 but it is fairly common in the valley of the lower St. John 

 [vide Bulletin No. XL Xatural History Society, St. John). 



Apeltes quddracus Mitchill. Shieldless Stickleback. 



This is a diminutive denizen of the brackish ditches 

 and ponds that are found in marsh lands near the mouths 

 of small rivers aftected by the tides. The specific name 

 quadracus refers to its dorsal armature, consisting of four
