does not accord satisfactorily to the plant which Postels and 

 Ruprecht called under the name Dumontia hydrophora. In 

 Tange p. 280, Ruprecht observed that in the Ochotsk coast 

 there can be no alga existing other than D. hydrophora which 

 comes closer to the description of Ulva glandiformis. He came 

 to this conclusion after referring to Halosaccion soholiferum var. 

 simplex and H. microsporum. But he could not free himself 

 from encountering to various difficulties in reviving Gmelin's 

 species. I can not restrain mentioning Colpomenia sinuosa f. 

 deformans Setch, et Gard. ( = Scytosiphon bullosus Saund.) to 

 refer to Viva glandiformis. This brown alga may attain often 

 to the height of 9 inches, has a short narrow stipe, grows mul- 

 ticipitally from a tuberous saccate base; frond is brown while 

 fresh, but often olive-green on drying; simple, hollow cylindrical, 

 round at the top and the base, and may occur on the coast of 

 Kamtchatka. I do not mean, however to identify this brown 

 algo to Gmelin's species. But it may be safeh' stated that 

 Gmelin's definition of Ulva glandiformis can hardly be applied 

 to Halosaccion Hydrophora in the same degree as to Colpome- 

 nia sinuosa f. deformans. By this reason the reviving the spec- 

 ific name glandiformis as has Ruprecht done is by no means 

 acceptible. 



RUPRECHT discussed also on the names Fucus saccatus 

 proposed by Lepechin, Lamouroux, and Turner. The name 

 in the conceptions of the former two, there is no doubt that 

 their plants have been different from H. Hydrophora. But Fucus 

 saccatus described and illustrated by TURNER comprised H. Hy- 

 drophora J. Ac. and H. hrmutn Rupr. but never soundly species 

 as Ruprecht thinks. Ruprecht himself distinguished too many 

 species out of one. Hence, by the rule of nomenclature, Halo- 

 saccion sa.cca.tum .shall stand in stead of //. glandi forme, And 

 consequently, the name H. saccatum Kjellm. ( Fucus saccatus 

 LEPECH.) must give its place for H. Lepcchini RUPR.
