In G. hyalina Hincks says that the hydrothecae have “the rim cut 
out into numerous shallow denticles of castellated form, slightly indented 
at the top," and in one or two of the hydrothecae of G. parkeri I find 
fragments of the rim which seem to present a similar aspect; I think, 
therefore, that the two forms are probably identical. The gonosome also 
appears to agree with that of G. hyalina. 
Clytia johnstoni (Alder). 
Hincks, 1868, p. 143: Hartlaub, 1901, p. 364. 
Some specimens from French Pass, which Hartlaub examined, are said 
by him to be undoubtedly a Clytia, and are, with somewhat less certainty, E 
referred to this well-known and widely distributed species. *

Orthopyxis caliculata (Hincks). 
Campanularia caliculata Hincks, 1868, p. 164: Farquhar, 1896, p. 459 (as var- 
makrogona). 
Orthopyxis caliculata Bale, 1914a, p. 74 (synomymy). 
The species which Coughtrey first described as C. integra and after- | 
wards as C. caliculata is placed by Farquhar under C. caliculata var. 
makrogona v. Lendenfeld (Orthopyzis macrogona Bale, 1914a, p. 77). The 
reason for this is not apparent: it seems equally probable, or more 80, 
that it may have been a true O. caliculata ; indeed, Coughtrey’s description 
of the gonangium does not apply very well to either form. artlaub | 
thinks us species is probably the same as his Eucopella crenata (Orthopyy£s 
crenata).
