8 ART. 7. — K. KISHINOUYE. 



Primary tentacles are not present ; in place of them we see 

 a dark pigment for each. 



The secondary tentacles are short, capped and situated on 

 the abaxial side of the bent extremity of each adradial lobe. 

 They are adhesive. The tentacular tract is somewhat triangular, 

 having two long sides and a short base. The tentacles, about 

 five in number and situated at the base of the triangular tract, 

 have each a thick, flattened disc on the abaxial side of its stalk. 



The central stomach cavity is very short, about equal in 

 length to the buccal stomach. The latter is likewise short and 

 presents a cruciate form in the transverse section. 



The gastral filaments (fig. 6) are rather few in number but 

 well developed, branched and crowded together in eight short 

 phacelli at the axial end of the genital glands. Apart from the 

 phacelli I have found a few, large and simple filaments at the 

 pylorus. 



The genital glands are represented by eight long and broad 

 bands, each of which consists of numerous large, laterally oblong 

 sacs and extends from the tip of the adradial lobes nearly to the 

 margin of the pylorus, where the longitudinal muscle terminates. 



The color is variable, simulating that of the environment. 

 It is sometimes dark brown, sometimes dark green. The nemat- 

 ocysts-groups are generally colorless. 



The diameter of the umbrella in a full-grown individual is 

 about 30 mm. ; total height of the body, about 7 mm. 



A single specimen of this medusa was discovered by Mr. 

 Oka in April, 1896, at Kogushi in the Province of Nagato. 

 He proposed to name it Lucernaria nagatcnxix, should the species 

 prove new to science. The somewhat popular description given 

 by him of the medusa as also his rather diagrammatic figures
