Body cylindrical, vermiform, in the unexpanded state 

 short in proportion to the breadth. The column is mostly 

 covered by a brownish epidermis, which is encrusted by a 

 layer of tine black sand, the grains of which are but 

 slightly adherent and may be easily rubbed off; upper 

 part naked, slightly ribbed, and with alternately nar- 

 rower and broader stripes of chalk-white. Tentacles 

 about thirty, slender, nearly as long as the diameter of 

 the disk, pointed, the inner ones longest, mostly black, 

 Avith a series of white spots along the inner side ; a few 

 smaller ones are of a pale gray color. Disk blackish ; 

 mouth orange within. 



Length, in partial contraction, about .5 inch; diam- 

 eter .25. 



Kagosima Bay, Japan, in five fathoms, black sand, 

 January, 1855. Dr. Wm. Stimpson. 



The only specimen preserved is so contracted as to con- 

 ceal the base by involution, and, as Dr. Stimpson neither 

 described nor figured the base, it is probable that he had 

 no opportunity to see it with the base extended. It is 

 possible that it belongs properly to Phellia. But its gen- 

 eral appearance, its tentacles, and its habits indicate that 

 it is a true Edwardsia.
