4. P. ECHiNDLATA, LamavcJc. 

 Sertularia setacea {Lister). 



Hab. : Not uncommon. Height f — 1 in. 



This species much resembles outwardly P. setacea, 

 but differs much in its smaller size and in several 

 microscopic particulars. The calycles occur on every 

 internode, and have a nematophore above and below 

 each. The gonothecse are ornamented with spinous 

 processes of considerable length. 



5. P. siMiLis, Sincks. 

 P. setacea {D. L.).

 l|in. 



This name is given by Mr. Hiucks to the species 

 figured as P. setacea by Dr. Landsborough (Pop. Hist., 

 plate ix. figs. 26, 26a). It is rather larger than the 

 preceding species, which, however, it much resembles. 

 The calycles are free at the extremity, and are separated 

 by two joints, a bare internode occurring between the 

 calycles, each of which has a single nematophore below 

 it.

Described by Mr. Hincks (A.N. H., 3rd ser., viii. 258) . 



Tliis minute species bears only one calycle on each

 calycles. There are two nematophores above, and one 

 below each calvcle.
