it to be Prlvetid. Tlu' two oospores, however, dilTcrent from 

 those observed in tlie otlicr s])eeies of Prlvetia, resulted from n 

 longitudinnl partition of tlie mother eell. Very often tlie two 

 oospores were obliquely situated in ;in oogonium but those in 

 serial disposition were exceedingly rare. This character would 

 not be important enough to warrant a claim for a new generic 

 position for the sj^ecies but must be included under the genus 

 Pclvclia with the additional note to the generic definition that 

 in certain members the spore-mother- cells are divided by a 

 longitudinal partition. 



Harvky'' mentions, though with some doubt, a plant under 

 the name Fucus furcaius, in the list of plants collected by Dr. 

 Ta'all at Esquimau, Vancouver Island, B.C. He remarks some 

 difficulty in referring his ])lant to that species and states that 

 it scarcely differs from Fucus Wrightii of Japan. In 1901, 

 I visited the " Minnesota Seaside Station " which stands on 

 the west coast of the same island. On the rocks above high 

 water mark, irrigated occasionally by the spray, I found a plant 

 which bears a close resemblance to the dwarfed forms of our 

 Pelvetia Wi'iffhtii. I had little doubt that it was the plant 

 Harvey meant in the above cited lines. Setciiell and 

 Gardner-^ seem to think that Harvey's plant |)robably be- 

 longed to a form of Fucus inßaius. 



On comparing the high tide forms of Pelvetia Wrightii f. typica 

 with the specimens collected by myself on Vancouver Island I find 

 very little difference between them. Ours, however, are more 

 yellowish when fresh and somewhat thinner than the Canadian plant. 

 It is possible that specific differences between them may be found.
