24 ART. 9. — K. KISHINOUYE ; 



HYDROMEDUSiE. 



Anthomedusse. 



Codonidae. 

 Snrsia rosariftf (A. Agassiz), 



The umbrella is long, ovoid, twice or a little over twice higher 

 than broad, and somewhat broader in aboral than in oral parts. 

 The manubrium is long and cylindrical, protruding a little out 

 of the umbrella-margin. It is nearly uniformly thick throughout, 

 the surface being covered with the genital gland. The tentacles, 

 four in number, are nearly twice as long as the height of um- 

 brella. The ocular bulbs are small. 



The manubrium is light red, while all other parts are colorless. 



Breadth 8 ram., height 17-19 mm., thickness at top 3-4 mm. 



This species was collected by Mr. Hiroshi Kato on the north- 

 eastern coast of Chishima (Kuriles) in September 1907. He told 

 me that medusae of this species are phosphorescent at night. 



Tiaridae. 



Catahleina multicirrata, n. sp. 



The umbrella is bell-shaped, about as high as broad. The 

 stomach cavity is large and cruciate. The manubrium is wide, 

 cruciate in cross-section, widened and a little reflexed at the 

 mouth, the margin of which is rich in minute folds. The four 

 radial canals are broad and give off minute lateral branches.
