shrimps, various species of Holothuries and star fishes. Of 
these we have analyzed only three specimens, viz. : 
1) Holothuria sp? (Mumeboshi) in the air dry state, 
from Yamaguchi prefecture. 
2) Holothuria sp ? (Ishiko) tlie so called sea cucumber, 
in the air dry state, from Okayama prefecture. 
3) Star fish (hitode), small variety, in the fresh state, 
from Hiroshima prefecture. 
The percentage composition was found to be as

Of these three, the sea cucumber (ishiko) has the highest 
manurial value on account of its considerable content in 
nitrogen. Mumeboshi and hitode are nearly equally rich
