TiiK two remarkable deep-sea Xemertines briefly described 

 below are unfortunately each represented in the ' Investigator ' 

 collecti(.>n by a single specimen only. As they are Museum 

 sjtecimcns and unique I have not thought it j)roper to make a 

 complete series of sections, but have had in each case a few 

 sections prepared from a small part of the body, removed in 

 such a way as to impair as little as possible the value of the 

 specimen as a whole.
