Y. OKADA : 



33. Liichenovora sugatniensis n. sp. 



Zoarium circular, 6.5 mm. in diameter, shaped like a thick disc, border- 

 ed with a moderately thick lamina. Zooecia form raised rays radiating 

 from the central area ; there are long and short rays which occur in nearly 

 regularly alternate arrangement. The short rays are composed of zooecia 

 in a single row ; the same holds good for the outer parts only of the long 

 rays, which in the inner parts are biforked and show in each of the branches 

 one or two rows of zooecia. The space between the branches is occupied 

 by cancelli forming a nearly continuous row with certain others of the 

 central area. Zooecial aperture elliptical, 0.10 x0.14 mm. large, the margin 

 indented so as to produce seven spiny processes, of which the outermost is 

 the longest of all. Cancelli very small in the central area, but growing 

 gradually larger towards the periphery, 0.02-0. 14 mm. in diameter. Ovicell 

 unknown. 



The above type specimen was obtained from Yodomi, 62-78 fms. A 

 second small specimen comes from Okinosé 336 fms. ; it was found attached 

 on a Hcxactinellid.
