41 
orange (Munsell, rY-R 7 /s), in spirit nearly 
white. Both main and dermal skeletons typical 
for the genus. 
Spicules. Megascleres: oxea .3 to .8 X .005 to 
.017 mm. Microscleres: absent. 
REMARKS: The tissues of this sponge are so 
heavily filled with opaque pigment cells that it 
is possible to study the arrangement of the skele- 
ton only with the utmost difficulty. 
Halichondria panicea (Pallas)

family HYMENIACIDONIDAE 
( de Laubenfels ) 
GENUS Hymeniacidon (Bowerbank) 
Hymeniacidon perlevis (Montague) 
Spongia perlevis (Montague, 1818, p. 86) = 
H. sanguinea (Grant) and H. caruncula 
( Bowerbank ) . 
OCCURRENCE: Waitawa Bay, Clevedon; Ana- 
whata; Stanley Bay. Lower midlittoral.

ward orange when in shadow. The earlier name, 
H. perlevis (Montague), almost entirely over- 
looked in the literature, must take precedence 
over the more familiar names.

rope; Mediterranean; West Africa; South Africa; 
Australia; New Zealand; Japan. 
family AXINELLIDAE (Ridley and Dendy) 
SUBFAMILY AXINELLINAE (de Laubenfels) 
GENUS Axiamon (Hallman) 
Axiamon erecta (Brpndsted)

Hymeniacidon erecta Brpndsted, 1924*, p. 
479, fig. 32. 
OCCURRENCE: Kawau Island. Commonly 
washed up on Auckland beaches. 
remarks : Two of Brpndsted’s species of Hy- 
menacidon, novae zealandiae and erecta, were 
relegated to Axiamon by de Laubenfels (1936: 
130). This species has never before been figured, 
and therefore a photograph is appended. 
DISTRIBUTION: New Zealand.
