Specimens examined : — 



Description : — Tentacles 20. Body bkmtly four-sided ; vcntruni 

 flat ; dorsum very high and closely beset with numerous small 

 round papillae. The sides and anterior end of the body thin out 

 almost membrane -like, and the tentacular circle is surrounded by 

 the flat membranous fold of the anterior body -end. Sexual open- 

 ing on a distinct wart. 



The ground color of the body yellowish-grey with darker 

 brownish spots and net-like tracings. Tips of the papillae deep- 

 red. Ventrum uniformly whitish-grey. Polian vesicles two. 

 Stone- canal attached. Calcareous deposits are C-shaped bodies 

 and tables, the latter with truncated spire terminating in four 

 dentate points. Incomplete rosettes numerous. Size up to 3 feet. 

 0—10 fathoms. 



Bemarks : — It is with a great deal of doubt that I refer the 

 Sanbon specimen to this species. Calcareous bodies have been 

 partly dissolved, and I am unable to make out the finer points 

 of the tables. There are simple disks mostly with four central 

 holes ; others have dissolved retaining only the X-like shape.
