8 ART. 5. — SANJI hüzawa: 



Oxea. — Usually slightly curved, nearly uniformly thick through- 

 out their length and sharply pointed at both ends, of which the 

 free end is sometimes provided with a more or less distinct nodi- 

 form ring. They occur in tufts projecting from the dermal surface 

 and with the inner J-J of their length imbedded in the chamber 

 layer. 



Oxea of oscular margin (textfig. 1, q, r, s). — Similar to those 

 just described, but on the whole longer, being 100-320/-« long 

 and 6-8 /^ thick. 



Note. — The above described species can not be identified with 

 any previously described. The specific name " Shimeji " is given 

 to it on account of its resemblance in form to certain fungus 

 known in Japan by that name. This sponge is common in the 

 neighbourhood of the Misaki Marine Biological Station. It occiu-s 

 in especial in abundance in the spring, attached on perpendicular 

 or overhanging faces of rocks below low tide- mark. 



Localities. — Misaki ; Öshima, Province of Shima.

(PI. I., fig. 3 ; PI. n., fig. 12 ; textfig. 2). 



The type-specimen of this new species (Sei. Coll. Spec. No. 20) 

 was collected from a depth of 429-572 m. at Okinose, Sagami Sea. 



Sponge consists of a sohtary person ; elongate, cylindrical, 

 slightly laterally compressed and bent at base, with an indistinct 

 oscular fringe ; surface slightly hispid, due to large oxea and trich- 

 oxea projecting here and there. The body is about 45 mm. 

 long and 9 mm. in gi-eatest breadth. It narrows towards both 

 ends. The sponge wall is about 1 mm. thick in the middle parts 

 of body ; nearer the osculum the thinner it becomes. The osculum
