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

The ground color of the body yellowish-grey with darker 

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

IicDiarl.-s -. — It is with a great deal of doubt that 1 refer the 

 Sanboii si^^cimen to this species. Calcareous bodies have been 

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

 of the tiibles. There are simi»le disks mostly with four central 

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