like, simple or once or twice sometimes thrice forked or divided 

 mostly in lower part, rarely proliferated profusely from the surface 

 near the base of frond, as shown in the fig. 2. The frond arises 

 from fleshy conical disc with a short thick tereti-compressed stem, 

 expanding into cuneate or broadly rounded sometimes reniform 

 base, with flat and entire margin, ending in simple obtuse or 

 ligulate or sometimes bifid apices. The plants attain usually the 

 length of 50-60 cm. in the breadth of 20-30 cm. and with the 

 thickness of 1-2 mm. in the upper portion much more thick in the 

 lower basal portion. The largest one ever I have get measured 

 2 m. by 13 cm. Utriculi cylindrical, often, slightly enlarged at 

 top into roundish knob with thin apical wall, 400-600 long, 50- 

 100 IJL thick, (the thickest 166 ,), mostly 6-9 times as long as 

 broad. Gametangia are produced in a few numbers somewhat 

 below the middle portion of an utriculus, oblong or elongato-ovate, 

 JSS-JS ! l by 56-75 /*. Colour bluish green, Substance felt-like 

 and rather closely adheres to paper in drying. 



Hab. : On rocks covered with sand, in open sea-shores, ex- 

 tending from low tide to deeper places (10 fathoms). Provs. Iki, 

 Tosa, Shima, Mikawa, Totomi, Suruga, Idzu, Sagami and Boshyu.
