Only plurilocular sporangia were met with; their shape was rather characteristic being oval-rectangular with roundish angles (Fig. 9 a and b); a few longer, clavate sporangia with undu- lated walls were also found (Fig. 9 c, d). The loculi are large, about 8 p high and 10 p broad. The oval sporangia were about 22 p broad and 33 p long; the longer, clavate ones up to 64 p long and 27 p broad. The sporangia are mostly sessile, rarely borne on a short stalk (Fig. 9 e).. Fig. 9. Ectocarpus rhodochortonoides n

Ectocarpus rhodochortonoides nov. spec. a, part of a plant with plurilocular sporangia and a rhizoid. b, a plurilocular sporangium and cells with chromatophores. c, a terminal plurilocular spo- rangium, d, a clavate plurilocular sporangium, e, a stalked plurilocular sporangium, f, base of a plant, (a, about 90:1; b—f, about 200:1). In the shape of the plurilocular sporangia with their large loculi our plant strongly reminds one of Ectocarpus breviarticulatus but in this species the sporangia are placed at right angles to the filaments while these are here curved upwards. In addition to this there is much difference in the vegetative parts of the plants. This species shows also some likeness to Ectocarpus varia- bilis of Mlle Vickers (Phycologia Barbadensis, Part II, pi. 31); but this form differs from mine in its much shorter cells which seem to be of the same length in the whole plant. Further the shape of the plurilocular sporangia is also different. The few specimens found were collected in exposed places in the littoral region.
