Forma ß lias its articuli cylindrical at tlie lower portions, some- 

 what compressed irj tlie middle, but the terminal articuli are long 

 cylindrical, siibattenuating toward tlie apex. Dense tufts are some- 

 times found, and sometimes isolated form ; in the latter case the 

 frond generally assumes a larger size (PI. IX. fig. 5). 



The second form y ahvays occurs in tufts, the terminal articuli 

 being homogeneousely cylindrical often attenuating toward the base. 



Although I refer our plant to the present species, the original 

 descriptions are not satisfactorily applicable to it. In ours the 

 genicula are rather small when compared with a specimen ex Herb. 

 Areschoug. Nevertheless, A. ephedraia, (Lamk.) Aresch. seems to be, 

 at any rate, a variable and inconstant species ; and there is no 

 little danger to claim an independent position for our plant. Ainphiroa 

 Gaillonii, Jjumx. is mentioned in tlie list of Algae collected by 

 Martens^) ; and a fragmental specimen doubtedly identified to it was 

 collected in the "Challenger Expedition" 2), on the shore of Oshima 

 harbour near the Kiushû Island. These specimens might have been 

 either of the above mentioned forms.
