The Astcrids tell a not dissimilar story: of the 26 species found 

 in the intertropical Australian seas, 3 only, or 11 ■'> per cent., were 

 found also at Port Jackson, while 8, or 30 per cent., were found also 

 in the western seas. 



Ophiuroidea. — Twenty-nine species were found in the intertropical 

 Australian seas ; and of these 3, or 10 per cent., were found also at 

 Port Jackson, while 16, or more than 50 per cent., were found in 

 the western parts of the Indian Ocean. 



It is useless, in the present condition of our knowledge, to appeal 

 to the Holothuroidea or the Crinoidea.
