light greenish-brown. The skeleton is a closely 
knit reticulation of systems of fibres ranging 
from unt- to multispicular. 
Spicules . Megascleres: oxea .14 mm. X .007 
mm. Microscleres: absent. 
Haliclona glabra f sp. nov. 
Fig. 4 
OCCURRENCE: Stanley Bay, under sides of 
boulders at low tidal levels. 
DESCRIPTION : A thinly encrusting sponge 
with even, minutely hispid surface. The oscules 
are few, minute, and scattered. Texture is firm 
and friable. Colour in life is dull cream, in spirit 
pale brownish-white. The skeleton is an iso- 
dictyal reticulation, the ascending fibres of which 
are triangular. Connectives are unispicular. 
Spicules. Megascleres: oxea .152 mm. X -007 
mm. Microscleres: absent. 
Haliclona heterofbrosa (Lundbeck) 
Renter a heterofibrosa Lundbeck, 1902, p 47, 
pis. 2, 11, figs. 8, 14; Br0ndsted, 1923, p. 
121; Hentschel, 1929, p. 983. 
OCCURRENCE: Rangitoto Island. Point Che- 
valier Reef. Under sides of stones up to half 
tide. 
REMARKS: Quite typical specimens, soft tex- 
ture, ranging in colour from creamy yellow to 
faintly purple. 
DISTRIBUTION: Arctic; Campbell Islands Sub- 
antarctic. 
Haliclona clathrata (Dendy) 
Reniera clathrata Dendy, 1895, p. 237; 
Brpndsted, 1923, p. 125; 1924*, p. 453); 
? R. spec. 4, Hentschel, 1912, p. 410. 
OCCURRENCE: Karaka Bay (St. Hellers). 
REMARKS: Single specimen: collet. ted agrees so 
closely in external form with the holotype of 
H . clathrata (Dendy) that there seems every 
reason to refer it to this species. Structure of 
the skeleton is closely similar.

This species appears to be a typical haliclonid 
insofar as the spicule sizes vary from specimen
