Figures

Planche 1 issued from : J. Corral Estrada in Tesis Doct., Univ. Madrid, A-129, Sec. Biologicas, 1970. [Lam.23].
Female (from Canarias Is.): 1, habitus (dorsal); 2, idem (lateral left side); 3, P1; 4, P2; 5, P3; 6, P4; 7, P2 (another specimen); 8, exopodal segment 3 of P4.

Nota: Cephalothorax with hump dorsally. Outer edge of 2nd and 3rd of exopodal segments of P2 to P4 with a nuber of teeth variable: P2 (2nd with 2-8 teeeth; 3rd with 6-7 proximal and 5-6 distal); P3: (2nd with 7-11 teeth, 3rd with 8-10 proximal and 0 distal); P4 (2d with 11-14 proximal, 3rd with 15-19 proximal and 9-20 sistal). Left P5 with 4 sgments in 2 females on 71 examined (abnorlality).

Male: 1, habitus (dorsal); 2, idem (lateral right side); 3, distal segments of A1; 4, P1; 5, P2; 6, P3; 7, P4; 8, P5; 9, distal portion of the exopodal segment 3 of P4 (another specimen).
Nota: The urosomal segments and furca in the proportional lengths 11-13: 25:12-17:13-14:18-20:15-17. Caudal rami divergent.

Species Acrocalanus andersoni - Planche 3 of morphological figures

Female (from off Georgia, USA)): B, habitus (dorsal); C, idem (lateral).

Nota: Cephalothorax about half as wide as long; with moderately developed dorsal hump. Nn partial suture between head and 1st thoracic segment. A1 reaching beyond caudal rami by about the last four segments.. Distal part of exopod segment 3 of P4 with 12-13 teeth on outer margin.

Species Acrocalanus andersoni - Planche 4 of morphological figures

Planche 4 issued from : T.E. Bowman in Bull. mar. Sc. Gulf Caribb., 1958, 8 (2). [p.119, Fig.1, A].
Female: A, A1.

Planche 5 issued from : T.E. Bowman in Bull. mar. Sc. Gulf Caribb., 1958, 8 (2). [p.120, Fig.2].
Female: A, P1 (anterior surface on left, posterior surface on right); B, P4 (idem); C, P3 (idem); D, P2 (idem); E, Md; F, Mxp.

Species Acrocalanus andersoni - Planche 6 of morphological figures

Planche 6 issued from : W. Vervoort in Atlantide Report., 1963, 7. [p.102, Fig.5].

Espèce Acrocalanus andersoni - Carte de distribution 4

Carte 4 issued from : T.E. Bowman in Bull. mar. Sc. Gulf Caribb., 1958, 8 (2). [p.122, Fig.3].
Distribution of A. andersoni, data for the 4 cruises combined. combined; T. N. Gill cruises 1-4 (10 Feb.-10 March, 17 April-14 May, 16 July-12 Aug., 17 Oct.-12 Nov.)
Nota: the species is an inhabitant of oceanic waters, and its shoreward distribution is limited by the cooler and less saline Carolinian Coastal water (Bumpus & Pierce, 1955). A. longicornis has a similar distribution, and the two species were often taken in the same net tow.
