 musculature, in most cases with two or three joints, and armed with numerous bristles, which 

 are most frequently strong. The other is considerably less voluminous, even rather small in 

 the sub-family Philomedinae, hyaline and weak, unjointed and only furnished with a few bristles; 

 there are no muscles in this process, which is moved only by muscles attached at its base.

In all the species of the family Cypridinidae which were investigated by me and of which 

 descriptions are given in this work, the latter appendage has only three bristles, all of which 

 ,ire placed near its distal end and which are almost always of the same type, rather long 

 and weak, in most cases finely plumous, a uniformity that may perhaps be considered to 

 indicate a great phylogenetic age. In the family Sarsiellidae this appendage seems, if one 

 is to judge both from G. 0. Sars's and C. W. Mtil.i.EU's drawings, to be still weaker than 

 in the sub-family Cypridininae; among other things it always seems to be provided witli 

 only two distal bristk's.
