exumbrella finely granular, flatter than a hemisphere. The bell-margin is 
badly damaged but there appear to be 6 to 8 cleft or subdivided velar lappets 
in each octant. Their general contours are rounded, and inter-lobular clefts 
extend radially a short distance up the exumbrella surface. 
The 8 rhopalia have each an ocellus, but no exumbrella pit. Perradial 
diameter of arm-disk, 55 mm.; width of subgenital ostia, 34 mm.; width of 
perradial columns of arm-disk, 12 mm.; subgenital porticus wide and unitary; 
naked upper arm, 20 mm. long; length of the abaxial side of the mouth-bearing 
part of each arm, 35 mm.; length of the terminal naked axial filament of each 
arm at least 40 mm., but all are broken at their ends. 
There is a thick felting of short filaments upon the arm disk. 
The circular muscles are unitary, being only partially interrupted in the 
8 principal radii. ' 
The 8 radial-canals are each about 3.5 mm. wide, and in addition there are 
about 8X10 slender radial-canals, all of which anastomose with one another 
and with the 8 chief radial-canals, forming a wide network in the subumbrella. 
In formalin the 8 chief radial-canals are violet. 
Schultze describes this medusa from Ternate and from Amboina, Malay 
Archipelago.
