Happon—The Actiniaria of Torres Straits, 435 
BUNODEOPSIS, Andr. 1880. 
Aliciidee with very delicate tissues. Column short, beset proximally with pedun- 
culate or sessile vesicles, the vesicular area much broader than the column. Ten- 
tacles elongate, readily retractile. Sphincter muscle feebly developed ; more than 
six pairs of perfect mesenteries. 
B. strumosa, Andr. 1880, Bay of Naples; B. Antiliensis, Duerd., 1897, Jamaica ; 
B. Australis, n. sp., Torres Straits. 
Bunodeopsis Australis, n. sp. 
(Pl. XXIII, figs. 9, 10:) 
Form.—Body columnar, pedal disk moderately expanded, with a single row of 
sessile vesicles at base of column. ‘Tentacles relatively very long, entacmzeous. 
Oral disk of greater diameter than column; mouth may be prolonged into a 
prominent cylindrical cone; no gonidial grooves. 
Colour.—Body, oral disk, and cone, translucent white; base of column with 
yellow streaks; tubercles yellowish, tipped with violet. Tentacles creamy buff, 
the basal portion of the oral aspect of the two inner cycles (6 +6) madder-brown, 
central portion with very fine lemon-yellow spots, giving a granular appearance, 
distant portion with two very faint brown rings; remaining tentacles paler in 
colour, without the brown basal mark. Lips of mouth violet. 
Dimensions. —Height of column, 3 mm. ; length of tentacles, 10mm. ; diameter 
of oral disk, 5mm. 
Hubitat.—Albany Pass, Cape York, 10 fathoms, August 27, 1888. 
This is almost certainly an immature form, but I think it is sufficiently charac- 
terised to deserve aname. It is probable that additional vesicles appear at the 
base of the column as the animal increases in size. 
Family.—Puyiiactina, Andres, 1884. 
Hexactiniine with a smooth, or more or less verrucose, column, the upper por- 
tion of which is produced into tentaculate, club-like, or frondose lobes; the 
capitulum varies in form and extent; the tentacles are simple and subulate. 
Sphincter muscle endodermal, variable in amount of development. Two gonidial 
grooves. 
Although it is risky to rely upon external characters in Actiniarian taxonomy, 
I venture to place together a number of genera which agree in possessing prolon- 
gations from the margin of the column. ‘The family was established by Andres
