The supply along the shore at the dates mentioned is so abundant 

 that it can be easily provided for class use in most of the laboratories of 

 the country. This year the plant appeared with the gale of October 23 r 

 the earliest date noted, and the specimens were the largest yet found

Preliminary note on the synonomy of Entothrix grande Wolle 

 Two years ago, through the kindness of Rev. Francis Wolle, Bethlehem, 

 Penn., I received specimens of his Entothrix grande. Upon a careful 

 microscopic examination of the material I found it to be an undescribed 

 species of Lemanea. I have also had an opportunity, through the courtesy 

 of Dr. Farlow, while at his laboratory during the past summer, of verify- 

 ing my observation by an examination of Entothrix grande Wolle, Rab. 

 Alg. Europ. no. 2538. The species belongs to the section of the Lamanea- 

 cex, for which Sirodot 1 retained the generic name Lemanea Bory. The 

 dense coil of enveloping filaments which surround the central axis of the 

 tube, as well as the two or three layers of cells in the cortex, shows the 

 affinity of this species with Lemanea catenata Kiitz. and L. nodosa Kut£ 

 If the enveloping filaments of the central axis are carefully dissected 

 away one could not fail to see the Lemanea structure. Mr. Wolle erred 

 also in associating it generically with Harvey's 3 Tuomeya fluviatilis. 1 have 

 also to acknowledge the favor of Dr. Farlow in permitting me to examine 

 type specimens of Tuomeya fluviatilis Harv. from Harvey's herbarium. 

 Wolle's figure 4 of Tuomeya fluviatilis, which, by the way, he states is 

 ideal, since he did not have an opportunity of examining specimens, 

 bears not the slightest resemblance to the habit of the type species, which 

 is more nearly that of Batrachospermun moniliforme, while it is also more 

 nearly related to Batrachospermum in structure. 



I hope in a forthcoming paper to give a more detailed account of the 

 structure of Lemanea grandis than can be given here. I have arranged 

 the synonymy as follows : 



Lemanea grandis Atk.
