as the armature of the tentacle club should be subject to a consid- 

 erable degree of variation among its constituent elements, so that 

 its great constancy in the present series is really quite surprising 

 and indicates that it may prove especially important in distinguishing 

 species. The discovery of males of this species should throw an 

 interesting light upon the entire subject. 



In gross aspect and general outline of the body there is great 

 variation, depending upon the conditions of preservation. The 

 greatest individualities observed are in the form of the mantle. 

 Sometimes the outline tapers smoothly and regularly from the 

 anterior margin, or there may be a pronounced bulging near the 

 middle, or sometimes a general inflation of the whole.
