Styli up to 1200 /f, asters 16 // and 30 — 10 miles N.W. of Cape 
Maria van Diemen. 50 fathoms. Hard bottom. 5/1.1915. Styli up 
to 700 and asters 16 //, (I have found no big asters). Another 
specimen from the same locality, but much larger, has: Styli up 
to 4000 fi, asters 12—15 //, and 70 // (scarce). — Off New Ply- 
mouth. 8 fathoms. Hard bottom. 12/1.1915. Styli up to 1800 //, 
asters 15 //, and 40 //. 
Hitherto known from several localities ranging from the Medi- 
terranean to the Philippines; (vide for details De ndy 1916).

Hen and Chicken Island, Hauraki Gulf, 50 fathoms. Hard bot¬ 
tom. 30/XII.1914. 5 specimens. 
Globular or somewhat elongated, largest specimen 15 mm in 
diameter. The surface is strongly hispid on account of the spicula- 
fibres lifting the dermal-membrane up into small conical elevations, 
and piercing these at the top; this feature is easily seen with the 
naked eye, as the spicula-tufts outside the sponge-surface reach a 
length of one mm, or even more; small orifices in the dermal- 
membrane, occur here and there, mostly hiding under an over- 
shading spicula-tuft; they are leading into spacious cavities lying 
just under the dermal-membrane, but over the cortex; these cav¬ 
ities often appear as small tents between the spicula-tufts. Con- 
sistence of the sponge hard; colour whitish. The ectosome is ca. 
0,5 mm thick, in a section it appears bluish against the yellow 
choanosome. 
Skeleton typically radiate, consisting of long spicula-fibres run- 
ning from the center of the sponge towards the surface right through 
the dermal-membrane, making the surface strongly hispid; in the 
interior the fibres are mainly made up of long siender oxea, while 
the dermal-tufts are mainly made up of triaenes; in the ectosome 
are placed shorter curved oxea, arranged almost perpendicularly to¬ 
wards the surface as rows of palisades; the before mentioned der- 
mal conical elevations, raised by the projecting main fibres, are to 
a great extent filled up with small curved oxea, which are so placed.
