of the ‘Challenger’ Report (p. 269), inasmuch as that sign 
means that the species was “ previously known, but found in 
the district for the first time by the ‘Challenger’; ” and, on 
his own showing, he had seen in the British Museum, some 
ten years previously, specimens from Masbate and the Philip- 
pine Islands. 
The preceding remarks show into what confusion the species 
of this genus, with a literature more scanty than most, have 
been allowed to fall, and the thanks of systematic naturalists 
are due to M. de Loriol for directing attention to its con- 
dition. 
XIUI.—On new Stylasteridee, with Remarks on some recently 
described Forms. By J. J. Quetcu, B.Sc. Lond., Assis- 
tant, Zoological Department, British Museum. 
THE four species herein described as new are founded on speci- 
mens in the collection of the British Museum. Special interest 
is attached to D. breviserialis, owing to the very great obli- 
teration of the lateral furrows of cyclosystems, except at the 
distal parts of the ccenosteum ; and also to Adlopora ochracea, 
in which the number of the dactylozooids in each cyclosystem 
is very limited, being usually only three or four. ‘The locality 
of Stylaster pulcher is specially interesting among the Hydro- 
coralline. In describing the colours of the specimens I have 
had reference to Werner’s ‘ Nomenclature of Colours.’ 
Allopora ochracea, un. sp. 
Ccenosteum of a reddish-orange ochre colour, branched, 
compact, irregularly flabellate; branches thick, spreading, 
slightly flattened and obtuse at the ends; surface nearly 
smooth or finely granulated ; cyclosystems closely placed on 
all parts, often in irregular series, being about *d millim, to 2 
millim. apart, of very variable structure, but not raised above 
the general surface of the coenosteum ; dactylopores very few 
in each system, variable in number, from 1 to 5, generally 3 
or 4, very rarely absent, small, subcircular, placed irregularly 
around the gastropore, with cavities always distinctly separa- 
ted, and occupied by a relatively large hirsute style ; gastro- 
_ pores about ‘4 millim. in diameter, circular, rather deep, with 
a thick, rather short, hirsute style; ampulle large, about 14 
millim. in diameter, vesicular.
