GENUS Adocia (Gray) 
Adocia parietalioides , sp. nov. 
Fig. 6a, b 
OCCURRENCE: Rangitoto Island; littoral. 
DESCRIPTION: An encrusting sponge with 
even, porose surface. Oscules small, 1-2 mm. in 
diameter, few in number, and level with the 
surface. Texture firm and friable. Colour in life

faintly pink, in spirit pale brownish white. Main 
and dermal skeletons unispicular. 
Spicules. Megascleres: oxea .15 X .01 mm. 
Microscleres: absent. 
REMARKS: This species is most closely related 
to A. parietalis (Topsent) from the Mediter- 
ranean, from which species it differs in: (a) the 
absence of subdermal canals radiating from the 
oscules; (b) the character of the undersurface 
of the free edges (which in A. parietalis "releve 
. . . et y developpe a sa face inferieure un feutrage 
plus serre des spicules ...”); (c) the size of 
the oxea, which are .01 mm. in thickness, as 
opposed to .005 mm. in A. parietalis. 
Adocia venustina, sp. nov. 
Fig. -la, h 
OCCURRENCE: Noises Islands, in mouth of 
cave; Rangitoto, in mouth of cave. 
DESCRIPTION: A sponge ranging in habit 
from encrusting to massive and depressed. Sur- 
face is uneven and glabrous. Oscules are numer- 
ous, subpapillate, 1-3 mm. in diameter. This 
sponge is of firm, friable texture. Colour in life 
yellow, in spirit dull yellowish brown. The main 
skeleton is isodictyal or sub-isodictyal, chiefly 
unispicular, but having occasional bispicular as- 
cending fibres. The dermal skeleton is unispic- 
ular with mainly triangular mesh. 
Spicules. Megascleres: oxea .1 X .004 mm. 
Microscleres: absent.

OCCURRENCE: Rangitoto sublittoral fringe. 
REMARKS: The species is represented by 
cushion-shaped masses up to 1 cm. thick, pale 
cream in colour, with firm uneven surfaces. The 
oscules are scattered, 1-2 mm. in diameter. 
Skeleton is a loose subhalichondroid reticula- 
tion, mainly unispicular, of oxea tending to be
