general appearance to the frond a resemblance to a form of 

 Chondrus crispus. 



In a smaller form of frond, the processes are seldom 

 elongated and divided, and they may Ijc often entirely absent 

 on the surface of segments. In a complanated process, which 

 is practically a reduced ramified branchlet, two or three 

 cystocarps may be found side by side. This form accords 



exactl}' with G. paciiica 

 KjELLM. Both typical 

 and this form may be 

 linked by gradual tran- 

 sitions. An extremely 

 simplified and small form 

 of Kjellman's plant is 

 often difficult to separate 

 from G. ochotensis which 

 will be enunciated below. 

 G. sitchensis Rupk., 

 though it is not re- 

 presented within our 

 boundary, is here sketched from the original specimen. It is 

 nothing but G. papillata J. Ac. and which has been mentioned 

 bv the American botanists as a form of G. mamillosa. 



Locality. Kurile Islands(!); Hidaka Prov.(!); Hakodate(!);

The present species stands close by G. unalaskensis RuPR.
