jrr.v loco.] YENDO— NOTES ON ALG M NEW TO JAPAN. 129 



I mention again a species hitherto in query among the algo- 

 logists. The species has been described from a material collected 

 by Chamisso in the Sandwitch Islands. It is characterized 

 by having capilaceous frond, sparingly ramose, and long pe- 

 dunculated, clavated stichidia. 



On the Pacific coast of the middle Japan we have a form 

 of Gelidium which exactly agrees with the definition given by 

 Kutzing. In Awa province it is sometimes collected in a 

 large quantity for the purpose of supplying the material for the 

 agar-agar.
