Of the systematic position of the present plant I am in doubt, 
whether it should be placed in ひがが ひれが の ia or in Poly o でら s. According 
to Pro じ J. Agardh's view (Till Alg. Syst. IV p. 17) the nenmtheciose 
collection of cystocarps in tenumaj— ‘segments separates Polyopes fVom

lateral proliferations which れ re shorfc niid roundish, and are 执 Iso formed 
じ ke a nemathecia below the apex of lateral elongated pro じ fera/tion ん 
They are again found below the apex of terminal non-pro じ ferous seg- 
ments, tlioiigli not む eaueufc in case. Thus my plants seem to me to 
stand in an intermediate position between Polyopes and Cryptcmem/ia. 
But owing to the prevalence of the presence of cystocarps in lateral 
i)roliferoi!s segments, I think that it is more proper to place the pre- 
gent plant in the genus Ch’yptoTiemia. 
Ne 又 t， I took the s む ucjture of fVond into consideration. In Oryjp- 
tonemia the frond is composed of three strata, there being an inter- 
mediate slratum of roundish cells Let ween cortical minute cells and 
medullary filamentous layei\ In Polyov を s, I doubt tlie presence ot in- 
termediate cells. On compairing it with my Poly opes Polyideoides I 
find that the present species has an int げ mediate layer, wh り e in the
