14 ART. 5. — SA^^^ hözawa : 



Trichoxea of oscular margin. — Slender, quite straight, sharply 

 pointed at inner end, generally broken off at outer end. A large 

 example with broken outer end measured 590 /^ in length and 4 // 

 in thickness. 



Trichoxea of dermal cortex. — Slender, hair-like, generally much 

 thinner than those of the oscular margin, measuring about 2 /^ in 

 thickness. 



Note. — This form seems to be quite distinct from any of the 

 hitherto known species. Grantcssa lanceolata (Beeitfuss)^^ may be 

 looked upon as its nearest ally, though showing some marked 

 differences in spiculation. 



Localities. — Okinose ; off Sunosaki ; Entrance of Enoura, Su- 

 ruga Bay.

Sixteen specimens of this species have come under my ob- 

 servation. Thirteen of them (Sei. Coll. Spec. Nos. 6-17, 29) were 

 collected by K. Aoki at Doketsba in the Sagami Sea from depths 

 varying from 185 to 214 meters ; one (Sei. Coll. Spec. No. 30) came 

 from Jôgashima (Misaki), while the remaining two (Sei. Coll. Spec. 

 Nos. 31, 32) were obtained by Prof. Ijima from the shallow bottom 

 in the neighbourhood of the Misaki Marine Biological Station. 



All specimens in the first group are sohtary tubular indivi- 

 duals attatched by the narrowed base. They are provided with an
