were still in growth and had the new branches beset with long 



brown hairs. One specimen dredged in August was still beset with 



hairs while hairs were wanting in the other specimens gathered in 



August and September.

The plants collected are on the wiiole well-developed and attain 

 a length of over 30 cm. The growth has ceased and the hairs are 

 thrown off in August. — Found in depths from 4 to 11 meters, and 

 perhaps deeper.

A very badly preserved, ca. 4 cm. long fragment of a tubular 

 brown alga without base and upper part seems to belong to this 

 species. As it has neither sporangia nor paraphyses, the determi- 

 nation is however uncertain. It differs from Chorda through lesser 

 consistency and the structure of the frond.

Found in small quantities on older fronds of Turnerella Pennyi 

 and on crusts of Lithothamnion, in the latter case forming ca. 2 mm. 

 broad crusts. In all cases brown paraphyses were observed; young 

 and empty plurilocular sporangia were also recorded. The plants 

 were collected in September.

This minute species was found on the upper end of a young 

 Alaria. The plants agreed with those found on young fronds of 

 Laminaria nigripes which I have formerly mentioned (1. c. p. 68 

 lowest). The plurilocular sporangia reach as a rule to the bottom
