Distributions and Comparisons of Centrolophus niger (Gmelin) and Centrolophus britannicus Günther (Centrolophidae) from the North Atlantic
The general distribution of Centrolophus niger in the North Atlantic is reviewed including the first two records from the Canadian area and two additional records off the New England coast to add to the four previously recorded from this area. Two new records from the Dana collections extend the dis...

The general distribution of Centrolophus niger in the North Atlantic is reviewed including the first two records from the Canadian area and two additional records off the New England coast to add to the four previously recorded from this area. Two new records from the Dana collections extend the distribution of this species westward in the oceanic area between Iceland and the Azores. All known records of the rarely captured Centrolophus britannicus are presented. These include 34 previously published records from the northeastern Atlantic, eight new records from the northeastern Atlantic and the first seven records from the northwestern Atlantic, from Flemish Cap and the southern Grand Bank to North Carolina.In separating C. niger and C. britannicus some meristic characters are useful: C. niger, D. 35–41, A. 23–25, P. 20–23, gill-rakers on lower limb 1st arch, 13–15; C. britannicus, D. 44–51 (one, 55), A. 27–33 (one, 25), P. 18–21 (one, 16), gill-rakers on lower limb 1st arch, 11–13.
