i ON RECENT POLYZOA. 525 
Challenger Report.’ Mr. Hincks, however, believing that Beania 
longs to the Bicellaria, rather than to any other group, I place it here 
out of deference to the author. It is not referred to by Mr. Busk, con- 
sequently it does not appear in his synopsis. I have therefore numbered 
it (20 ?). 
4 Genus (20 ?). Beania, Johnston. 
‘Zoarium sub-corneous or calcareous, erect or decumbent. Zocecia 
sessile, erect, scattered, united one to the other by a slender tube, 
originating from the dorsal surface or from the side near the base ; 
aperture occupying the entire front, the margin furnished with hollow 
"spinous processes arching over the opening; mouth terminal. Ocecia 
and avicularia wanting. —Hincks, p. 95. 
1. Beania mirabilis, Johnston; Hincks, p. 96, figs. 8-10, pl.iv. This 
is the only British species of the genus, and Hincks 
gives several localities besides the following distribution 
of this form :— 
Scandinavia; Adriatic ; Roscoff. 
a australis, Busk, ‘Brit. Mus. Cat.’ 
Patagonia. 
Swainsoni, Hutton. (See Hincks, ‘ Brit. Mar. Pol.’ p. 96.) 
An erect phytoid form, New Zealand. 
= admiranda, Packard (Hincks, op. cit. p. 96). 
Labrador. 
As members of the Bicellariadze, Mr. Hincks has instituted the two 
following genera for species found in his Australian collection. It is only 
fair both to Mr. Busk and to Mr. Hincks to say that in the ‘ Challenger ’ 
collection Mr. Busk has already figured (pl. vi. fig. 1) the Stirparia 
glabra of Hincks as Bicellaria stylites; but as Mr. Hincks’s name was 
published before the isssue of the Report the name is changed to that of 
B. glabra, Hincks (‘ Chal. Rep.’) ; and in a note Mr. Busk adds, ‘ Since 
the above was in type Mr. Hincks has described apparently the same 
form under the name of Stirparia glabra, and gives a full account of the 
peculiar structure on the zoarium and its stem from better material than 
- those at my command.’ I think that Mr. Busk will see that the pecu- 
liarities of this remarkable form demand its separation from Bicellaria 
proper, but not from the family in which Mr. Hincks has placed it. 
Genus Stirparia, Goldstein. 
‘Zoarium, consisting of erect segmented stems, chitinous or calcareous, 
and of celluliferous branches, which originate in more or kss fabellate 
tufts close to the summit of the segments. Zocecia of the normal Bicel- 
larian type, turbinate, somewhat free above; aperture looking more or 
less upward, turned obliquely inwards, inferior portion of the cells 
sub-tubular. Avicularia articulated.’—Hincks, ‘Ann. Mag. Nat. Hist.’
