3S4 THE VOYAGE OF H.M.S. CHALLENGER. 



Two facts shown in the above Table are worth notice : — 



1. Kepresentatives of each of the six living genera of Comatulse were obtained by 

 the Challenger, two of thern being new to science. 



2. Five-ninths of the recognised living species of Comatulse have been discovered by 

 British ships. This proportion will be largely modified, however, when the "Blake" 

 collection and those of the Continental Museums have been properly worked up.
