Specimens collected by Griccs and Rice at Anchor Point, 
Cook Inlet, measured as follows: length 13 m., 21 m., 22 m., 78 m.; 
width 232 cm., 175 cm., 170 cm., 123 cm., respectively. The first 
of these specimens had 220 sporophylls, the largest of which 
measured 65 cm. in length and 84 mm. in width. The width of the 
midrib was 53 mm. 
All of these plants were badly frayed at the tip, a great deal of 
material evidently having been worn off by the violence of the 
tidal currents. Regeneration from the base seems to be continuous 
throughout the life of the individual in this species. It is thus 
- impossible to say whether these specimens had at any time been 
longer than they were when collected. 
The weights found by our expeditions for portions of the fronds 
of Alaria fistulosa of the sizes given are shown in table III.

The deepest sounding made in an Alaria bed was 5 fathoms 
(Middle Islands, Alaska). 
Summary 
1. The observations of the writers do not tend to confirm the 
earlier statements of the great length of Nereocystis and Macro- 
cystis. 
2. Their observations on Alaria fistulosa confirm earlier state- 
ments of its length. Its maximum width was found to be more 
than twice as great as reported in literature that has come to the 
attention of the writers.
