Espèce Chiridiella pacifica - Planche 3 de figures morphologiquesIssued from : K.A. Brodskii in Calanoida of the Far Eastern Seas and Polar Basin of the USSR. Opred. Fauna SSSR, 1950, 35 (Israel Program for Scientific Translations, Jerusalem, 1967) [p.194, Fig.109].

Espèce Chiridiella pacifica - Planche 4 de figures morphologiquesissued from : G.A. Deevey in Bull. Mar. Sc., 1974, 24 (2). [p.460, Fig.12].
Female (from 32°10'N, 6°30'W): a-b, habitus (dorsal and lateral, respectively); c, Mx1; d, Md; e, P1; f, P2.
Scale at left for parts a and b; at lower right for parts c-f. Scales in mm.
Nota : Head and 1st thoracic segment separate. Cephalothorax 82-83 % of total length. Urosome about 21 % of cephalothorax length. Genital segment very protuberant ventrally. A1 24-segmented, not longer than cephalothorax. Endopod of A2 ¾ length of exopod.


Espèce Chiridiella pacifica - Planche 5 de figures morphologiquesissued from : G.A. Deevey in Bull. Mar. Sc., 1974, 24 (2). [p.461, Fig.13].
Female: a, A2; b, P3; c, P4; d, Mxp; e, Mx2.

Espèce Chiridiella pacifica - Planche 6 de figures morphologiquesissued from : G.A. Deevey in Bull. Mar. Sc., 1974, 24 (2). [p.462, Fig.14].
Male: a, habitus (lateral); b, A2; c, Md; d, left A1; e, Mx1; f, left P5; g, right P5; h, P3 (exopod segments 2 and 3 missing); i, P2; j, Mx2; k, Mxp (endopod setae not shown).
Scale on left margin for parts a; on right margin for parts b-k. Scales in mm.
Nota : Md and maxillae greatly reduced (suggesting that the male does not eat after his final molt. A1 longer than in female, reaching the urosome, both similar, neither geniculate. Endopod of A2 larger and slightly longer than exopod.
