Species Scolecithrix mollis - Plate 1 of morphological figuresIssued from : C.O. Esterly in Univ. Calif. Publs Zool., 1913, 11 (10). [Pl. 10, Figs. 14, 29].
Female (from S California): 14, abdomen and last thoracic segment (lateral); 29, forehead (lateral).

Nota: Rostrum bifid, with soft and rather delicate filamentsl.
The last thoracic segment has rounded lateral margins, the dorsal portion of the outline being indented.
Genital segment about as long as the 2nd and 3rd together, and 4 times as long asthe 4th.
Cephalothorax length about 1 mm.

Species Scolecithrix mollis - Plate 2 of morphological figuresIssued from : C.O. Esterly in Univ. Calif. Publs Zool., 1913, 11 (10). [Pl. 12, Fig. 61, 65].
Female (from S California): 61, P5; 65, exopod of P1.
Exopod length of P1: 247 µm. P5 length: 133 µm.

Nota: P5 [non fig.62, lapsus calami, but fig.61, C.R] 2-segmented; 2nd segment has a short, heavy spine on the distal end, a very heavy dentate bristle at the middle of the inner margin, and 2 tiny spines, one at the end of the segment, the other at the middle of the outer margin.
