The very numerous young specimens (by the hundred thousand) bear witness to the 

 excellent food conditions that must exist in Falkland seas ; it seems beyond doubt that 

 this Ophiurid must be a factor of considerable importance in the ecology and economy 

 of these seas. 



Plate VIII, fig. 2, represents a photo of a live specimen ; it is stated to have the " upper 

 side of disc deep purplish brown, with white plates; arms deep brown above". Some 

 few of the preserved specimens still show distinct traces of this coloration. 



That this species is not viviparous has already been pointed out by Ludwig {op. cit.) ; 

 I may add that it has, as was to be expected, separate sexes.
