10 ART. 7. K. KINOSHITA : ON SOME MURICEID CORALS 



ed with some foliaceous, longitudinally directed ridges, wliile the 

 remaining parts show closely arranged warts. The spicules are 

 0.6-0.3 mm. long. Beneath these spicules, there may exist two 

 pairs of smaller ones set en chevron^ but these are sometimes comp- 

 letely obliterated (PI. II., fig. 15, a). The sculpture on these 

 spicules is represented only by warts. Above the large opercular 

 spicules there are numerous, small (0.15 mm.), fusiform spicules 

 arranged longitudinally and closely disposed (PI. IL, fig. 16, 

 a). The pinnules are provided with a single slender spicule, resem- 

 bling the floating rib of mammals (PL II., fig. 16, b). 



The spicules of cœnenchyma are typical scales, slightly 

 imbricated and polygonal or elliptical in shape. The outer 

 surface is covered with rounded warts, just as in the case of 

 proximal calyx-scales. The size of cœnenchyma scales varies 

 generally between 2 and 4 mm. On the inner side of the superficial 

 layer formed by the scales, there are present a few small (0.4 

 mm.) spicules of an irregular shape, covered with granulated warts. 



The spicules are colories, but owing to the presence of pigments 

 in the tentacular region of the polyps, the polyp-cells appear 

 brown with a purplish tint. 



Locality: the coral ground of Uji Island, Province of Satsu- 

 ma, 80 fathoms ; collected by the author (June 1908).

This interesting species, which is evidently new, is represented 

 by a single dried specimen. The cœnenchyma is for the most 

 part rubbed off, only the terminal parts of branches remaining 

 intact (PI. L, fig. 4).
