Species Brachycalanus atlanticus - Plate 1 of morphological figuresissued from : G.P. Farran in Ann. Rep. Fish. Brch., Ireland, 1902-1903, II, App. 2, 1905. [Plate X, Figs.1-3].
Female (from W Ireland): 1-2, habitus (lateral and dorsal, respectively); 3, rostrum (ventral).


Species Brachycalanus atlanticus - Plate 2 of morphological figuresissued from : G.P. Farran in Ann. Rep. Fish. Brch., Ireland, 1902-1903, II, App. 2, 1905. [Plate X, Figs.4-9].
Female: 4, A1; 5, A2; 6, Md (mandibular palp); 7, Mx1; 8, Mx2; 9, Mxp.


Species Brachycalanus atlanticus - Plate 3 of morphological figuresissued from : G.P. Farran in Ann. Rep. Fish. Brch., Ireland, 1902-1903, II, App. 2, 1905. [Plate X, Figs.10-14].
Female : 10-14, P1 to P5.


Species Brachycalanus atlanticus - Plate 4 of morphological figuresissued from : D.F. Arcos in Rev. Com. Perm. Pacifico Sur, 1976, 5. [Fig. 11].
Female [non Male] (from 54°24.5 S, 69°12.7 W): 11, P5
Scale bar: 100 µ.

Remark: P5 seems different from Farran.

Distribution map of Brachycalanus atlanticus by geographical zones
Loc:
? Magallones region (in Arcos, 1976), SW Atlant., N Atlant. (Woods Hole, W Ireland, (55°N, 12°W)
N: 5
Lg.:
(45) F: 2,5-2; (229) F: 2,5; {F: 2,00-2,50}
Rem.: mesopelagic; epibenthic . After Pearson, 1906 (p.20) : vertical range down to 700 m.
For Othman & Greenwood (1988, p.357) the species, identified by Farran under this name is different.
