"The calycles of Plumularia pinnata are only 

 separated by a single joint, those of Plumularia setacea by

Hincks, continuing the description of this species 

 remarks (p. 296, line 7 from the top) : "A much safer 

 criterion (as regards distinctive marks of the species) is to 

 be found in the nematophores, which are scantily developed 

 and exhibit a very peculiar structure."
