Though I have little doubt that S. huttoni is only a synonym of the older 
S. insignis, yet as there are certain slight discrepancies in the accounts ot 
wn, I 
content myself at present with noting the similarity of the two forms. 
8. insignis is recorded from George Town, Tasmania; S. huttoni from “ New 
Zealand." 
Stereotheca elongata (Lamouroux). 
Sertularia elongata. Farquhar, 1896, p. 461: Bale, 1915, pp. 277, 262 (synonymy). 
I have given a pretty full list of references in the above-cited paper. 
Specimens from Lyttelton, in Professor Chilton's collection, do not differ 
in any respect from the small form abundant on the southern Australian 
coast. 
Fam. PLUMULARIIDAR. 
The genera of the Plumulariidae included in this paper are in accordance : 
with Bedot's classification D Notes systématiques sur les Plumularides, " 
Revue Suisse de Zoologie, 1 
Thecocaulus, proposed by та in 1915 as the name of a section of the 
genus Plumularia, comprising the species in which the rachis, as be as 
the hydrocladia, bears hydrothecae, is adopted by Bedot as a gen He 
excludes from it, however, those species in which the e hydrocladia produce 
secondary ramules, also bearing hydrothecae; these he refers to the genus 
Schizotricha, modified from Allman's genus of that name.

It would serve no useful purpose to cite all the numerous references 
and the many synonyms applied to this species by the early observers ; 
may point: out, however, that while Bedot and other authors refer to the 
species as “ P, setacea Linné,” others, including Hincks, quote Ellis as the 
author of the specific name. Though Ellis, in his text, calls the hydroid 
“ sea-bristles," he also names it * Corallina setacea,” which seems to be 
the first use of the specific na
