526 REPORT—1885. 
Genus Stolonella, Hincks. 
Loc.: Geraldton, Western Australia (Miss Gore). 
The generic description of Mr. Goldstein is revised so that the kindred 
species, S. glabra, may be included. 
The following is another peculiar Australian species, for which the 
eneric name is instituted by the author, ‘Ann. Mag. Nat. Hist.,’ vol. xi. 
p. 197, 1883. 
Zoarium consisting of a creeping stolon, and zocecia distributed upon 
it. Stolon chitinons, free in itself, but attached at intervals by adhesive 
branching discs, which originate from short stolonic offsets, jointed, 
more or less branched. Zocecia erect, scattered, always developed close 
to a joint, attached to the stolon by the pointed lower extremity of the 
dorsal surface, sub-calcareous, boat-shaped, aperture occupying the whole 
front, closed in by flattened spinous ribs united together ; orifice terminal. 
Stolonella clausa, Hincks (op. cit. p. 198, pl. vii. fig. 6). 
Loc.: Creeping over Fucus, Geraldton, West Australia (Miss Gore). 
Mr. Hincks remarks (p. 197, op. cit.) ‘that the true stoloniferous 
character of this form seems to call for its separation from Beania as 
represented by our British B. mirabilis.’ 
Family VII. Notamiide 
= Gemellariide, Busk (part). 
‘Zocecia in pairs, each pair arising by tubular prolongations from the 
pair next but one below it; at each bifurcation a new series of cells 
intercalated into the branches.’—Hincks, ‘ Brit. Mar. Pol.,’ p. 98. 
Mr. Hincks says, ‘the remarkable structure of the zoarium of 
Notamia bursaria entitles it to stand as the type of a separate family, .. . 
and the Australian genus Oalwellia resembles Notamia to some extent in 
the structure of the zoarium.’ 
In the ‘Trans. Microp. Soc. Lond.,’ vol. ii. 1849, Mr. Busk gave a 
somewhat exhaustive account of Notamia and its peculiar structural 
details. In the synopsis which prefaces the description of the Crag 
Polyzoa, Mr. Busk places Notamia as the first genus of his family Gemel- 
lariidz. Only one species described :— 
Genus 21. Notamia, Fleming. 
1. Notamia bursaria, Linn., Hincks, p. 100, pl. v. figs. 1-5 
= (?) Calwellia bicornis, W. Thomson. 
Family VIII. Gemellariide, Busk 
= Encratip® (pars), Hincks, ‘ Brit. Mar. Polyzoa.’ 
‘ Zoarium sub-membranaceous, flexible, continuous. Zocecia opposite, 
in pairs, unarmed.’—Busk, ‘ Chal. Rep.,’ p. 46. 
Excepting the genus Natamia, which Mr. Hincks takes as the type 
of his family Noramup2z, the family GemELLarups#, Busk, includes the 
same genera as originally arranged under it in the ‘ Brit. Mus. Cat.,’ to 
which others are added in the ‘ Challenger Report’; consequently as now 
arranged the whole appears to be a very natural group. 
Genus. Gemellaria, Savigny. 
»  Didymia, Busk.
