J a n i a t e n e l l a Kiitz.? Bougainville I., Sta. 26. This small sample at first seemed to resemble J . r u b e n s , but the upper branching was more spreading. The diameter of the lower axes ranged from 120-260 pm, which is not too different from J . r u b e n s , but the segment length below was only 1.5- 1.75 times the diameter and above to 2.0-2.5 times, which is too short for that species. In fact, it is rather short for J . t e n e l l a as figured by Kiitzing (1858, 8, pl. 85 11)
.

Lomentaria h a k o d a t e n s i s Yendo ? Kieta area, Sta. 21. These plants are smaller and less branched than L . s i n e n s i s Howe
(1924, p. 139, pl. 1 fig. l), which has been reduced to synonymy under L. h a k o d a t e n s i s , and the tetrasporangial branchlets seem to stand erect and to be sagittate to lanceolate in shape. The lower branches often curve down and attach at the tips.

Ceramiaceae
A n t i t h a m n i o n sp. Pulau Gaya area, Stas. 12, 12a. There was
abundant material of this plant, but unfortunately it was all sterile. The plants were about 5 rnm tall, growing on E n h a l u s leaves. The main filaments reached a diameter of 15-47 pm.
The branchlets were opposite or verticillate, of equal length, sub-simple low on the axes, but above closely alternately branched, not secund. The cells near the bases of the branchlets were 12-14 pm diam., near the tips 7.7-9.3 pm.
No gland cells were found.
