are found at the junction of the oral suture and near the lower 

 end of the oral arms. 



The gastrovascular system is remarkable in many points. It 

 forms a very fine network in the subumbrella (fig. 13). The 

 eight ocular canals run straight and are easily distinguishable 

 from others, though there exists no special difference in calibre. 

 Between each two ocular canals we find five or six canals which 

 soon divide into numerous smaller ones. Radial muscular ridges 

 receive many small blind branches from the network of the canal 

 system. The circular canal is wanting. Each velar lobe receives 

 a very minute network of the canal system. The central stomach 

 cavity is nearly circular, not cruciate. No canal is contained in 

 the oral disc, but in its lower surface a canal is seen in each of 

 the adradial ridges or keels of the oral crisps (fig. 12). 



The umbrella in the preserved state measures 14 cm. in 

 diameter. 



The animal is colorless, with the exception of the margins 

 of the velar lobes which are brown. 



The medusa is known from Misaki. It is found in the 

 colder months of the year.
