The umbrella is hell-sliaped, somewhat (juadraiigular. The 

 umbrella-margin is nearly straight, not lobed. The manubrium 

 is quadrangularly prismatic, hangs down iVoin the gastric peduncle, 

 and ends with an expanded mouth, the oral lobes of which are 

 well developed. From the proximal part of each perradial canal, 

 there hang down about ten dichotomously branched gonads. These 

 are a little longer than the manubrium and almost reach the level 

 of the velum. Each perradial canal has from fourteen to sixteen 

 long, lateral branches on each side. These branch-canals are 

 again divided into numerous small subbranches near the distal 

 end. Besides, there are many, short, centripetal canals ; these 

 are simple with the exception of a fe\v in interradial corners 

 which are branched. Numerous tentacles are arranged in about 

 two or three rows ; they number about thirty in each quadrant. 

 Peculiar is the fact that many tentacles are divided. 



A very tine specimen was obtained at Korsakoff by Prof. 

 Ijima's party on September 19, 1906. It is very well preserved 

 in formalin, and measures 50 mm. in breadth and 60 mm. in height.
