Enteromorpha quaternaria Ahlner in Wittr. et Nordstedt Alg. exsicc. Nr. 138 and 139. I have only met with this species in one place where it occurred in the litoral region. Most of my specimens are fully unbranched, but somewhat branched specimens occasionally occur. The frond is 13—14 fi thick and the height of the cells (in transverse section of the frond) is about equal to the breadth. Fructiferous specimens have been gathered in August. NW. I c el. Broddanes. Enteromorpha Linza (L.) J. Ag., Ulva enteromorpha a, lanceolata Le Jol. Liste p. 42. The species occurs in the litoral region, especially in pools. The Icelandic plants are 3— 40cm. long, 0,5 —3cm. broad and 30 — 40/^ thick. Fructiferous specimens have been gathered in Sept. — Octob. The specimens gathered by Ostenfeld at Reykjavik in August belong to the f. undulata Le Jol. (1. c), but the specimens, which I collected at Reykjavik in October, usually had a plain margin and the specimens from Hafnarfjöröur (also collected in October), had an undulate margin below and a plain margin above. Some of the specimens from Eyrarbakki (collected in May) resemble somewhat the f. angusta Le Jol. (1. c). SW. I cel. Reykjavik (CO.); Hafnarfjöröur. S. I cel. Eyrarbakki.

This species, which is exceedingly multiform, is common everywhere along the coasts of Iceland, and occurs both in exposed and in sheltered. Fig. 4. Per
