Hedwi- gia, Bd. 28, 1889, p. 309. A few specimens were found in a collection of Acetabularia crenulata. They agree very well with the description of Howe (1. c. p. 323—4). Specimens with gametangia were found, in which before decalcification the gametangia stuck together in the calcareous mass mentioned by Solms. The gametangia were about 70—80ll in diameter. Corona superior and inferior have both rather thick walls and agree very well with the ligures by Solms (1. c. pl. 3, fig. 12 and 14); the first has two hair-scars one behind the other. The disc is flattened or a little bent upward. On the rounded apex of the rays a small apiculum is to be found in these specimens. While these specimens were found in shallow water growing on small shells and stones on muddy bottom together with A. crenulata, I have further found some very few individuals (Fig. 8) in deeper water and as these specimens seem to show a few differences I shall „. 0 . 7 . 6 7 describe them a little more in detail. Fig. 8. Acicularia bchenckii (Möb.) Solms. (About 21/2—l). The plants were of intermediate size; the largest I have seen had a disc about 8 mm. broad. The length of the stipe varies from 1 to 2—3 cm.; it is vigorous, rather thickwalled and has no spindle-shaped swellings. The disc is flattened; it has about 50 rather thin- walled rays which are all firmly united even after treat- ment with acid. The wedge- shaped rays end in a rounded apex which often quite lacks the small apiculum (Fig. 9 A). The corona superior and.
