 Some of the tube-feet of arms B and C, and of D and E, were 

 attached by their disc-like ends directly to the body of the fish,

 humped up in the usual feeding posture, and the papulae stood 

 out conspicuously upon the upper parts of the disc and arms. 



The Starfish apparently found the Pipe-fish too heavy a load 

 to support for long in this awkward attitude, and it later shifted 

 arms A and D to the positions shown in fig. 2, at the same time
