 smaller buttons are about 70 li in length and are often knobbed 

 and have about six pairs of holes.

The spicules consist of tables and buttons.

 persist when the others are broken. Many of the tables, there- 

 fore, have only four peripheral holes. 



Diameter of tables up to 55"5 li.

This is undoubtedly the same species as Holothuria gallensis 

 Pearson (29), so that this latter name must be included as one 

 of the synonyms of Holothuria scabra.
