 no more to l)e hesitated to inlorm its oeeurrcnee on Japanese 

 eoast. Very likely, Harvey tcjok the smalleness of his Japanese 

 spceimens as a peeuliarity ol them and placed them in a varietal 

 r£ink ol the Kuropean form.

Speeimens oi Sporochnus have been often found on our coasts. 

 Okamura reported with query Sp. Aloorei Harv. from Enoura, 

 Suruga Prov., in his Nippon Sorui-AIeii, Ed. I, p. Ilio, 11)02. 

 In its 2nd. edition, p. IGl, published this year, he mentions only 

 one species Sp. hcrcaleus J. Ag. again with query, a])parcntly 

 discrediting his former information, though whatever comment 

 is not stated about it. Examining the material at my disposal, 

 I found two distinct species among them. One of them agrees 

 with Sp. scoparius Harv. and the other with Sp. radiciformis 

 Ag. 



Our specimens of the present species have the receptacles 

 generally obovate or elli])tieal, some young ones b2ing nearly 

 globular. Peduncles are once or twice as long as receptacle, the 

 entire length of a ramidct measurinsj; 2.5—3.0 mm. Ramification 

 is less decompound than it is represented in I'hyc. Austr., 1*1. 





Sp. sjjiuvi'occpluilus KuTZ. is probably Lo be comljiiicd wIlIi
