the median diameter ; the third and following have slightly produced 

 finely spinous distal edges ; the following pinnules are small and weak. 

 This species is closely related to Euantcdon moluccana; it is some- 

 what larger than the type (and only known specimen) of that form, 

 and shows the following differences ; the cirrus segments are propor- 

 tionately only about half as long, with both the proximal and distal 

 dorsal edges thickened and prominent, the entire dorsal surface in E. 

 moluccana being straight and smooth ; there is much less difference in 

 proportions between the proximal and terminal cirrus segments than 

 in E. moluccana; the proximal pinnules are essentially the same in the 

 two forms, but in E. moluccana the component segments are longer 

 and the distal edges are smooth and not produced ; the synarthrial 

 tubercles are less prominent than in E. moluccana.
