The form a is widely distributed in the middle part of Ja])an as 

 well as in Hokkaido (Vesso). Tt is found densely covering large 

 ])atches of rocks from the liigh water mark to 2-3 feet below the 

 surface. Under the influence of surrounding conditions it is generally 

 bleached into a dirty white or greenish colour, ft attains hardly to 

 2-4 cm. in lieight with the axial articuli 1 mm. long, 0.5 mm. or 

 less wide ; the pinnae being much thinner. Very often a laciniated 

 articulus is found at the top of a, branch. 



The second form .9 accords iji several respects ^x\Û\ J. ffextlis ol 

 Kjellman. Ihit our i)lant is smaller than his, measuring only 4-8 

 cm. in height ; its articuli are cylin(h'ical throughout the whole part 

 of the frond, gently attenuated toward the apex; the axial articuli 

 measure 1.5 mm. in length and 1. mm. in width ; the uppermost ones 

 being only as thick as a brittle. 



The form c of Areschong in J. Ag. Spec. Alg. 1. c. might prove 

 the same as our form ;-. They accord very well on the points 

 remarked by him, except in regards to the shape of the ramiferous 

 axial articli, which an; much moi'c compressed and more or less 

 costated in our s]X'cimens.
