For our knowledge of this beautiful little Iiydroid we are indebted to Mr. Rotch, who 

 obtained it in the Channel Islands. Among the whole range of hydroid trophosonies there is not 

 one more remarkable. It is absolutely unique in the ramified condition of the tentacles of the 

 hydranth. Unfortunately no gonosome had been developed in any of the specimens collected, 

 and we wait with much impatience for the discovery of this important element. 



The accompanying woodcut has been made from a specimen in Mr. Rotch's aquarium.
