The Echinoderms collected by the " Huxley " from the 

 North Side of the Bay of Biscay in August, 1906. 



By 



W. De Morgan. 



My thanks are due to Dr. Allen for permitting me to examine this 

 collection. 



In all 292 specimens were obtained, but of these 16 were young 

 immature Asteroidea and Echinoidea. It is impossible to identify 

 these with any degree of certainty, and I have not hazarded an 

 opinion about them. 



The remainder belong to 17 genera and 24 species. The Ophiuroidea 

 were particularly numerous, 190 specimens belonging to that class. 



The classification followed is that of Professor MacBride in the 

 Cambridge Natural History.
