Channel, Kawaii Isl., Hauraki Gulf. 10 fathoms. Hard bottom. 
29/XII.1914. The specimen from the first locality is massive in 
outer form, not lamellar; the surface exhibits all over subglobular 
prominences as seen on Dendy’s fig. 2, PI. V to the left. The 
specimen from the second locality is only a fragment; the sponge 
has apparently been lamellar. General structure, skeletal arrange¬ 
ment, and spicule-measurements agree closely with the type. 
Hitherto known from 7 miles E. of North Cape, N. Z.

Three specimens, the two only fragments, somewhat macerated; 
all from Slipper Isl., the coast, at low water. 20/XII.1914. 
The cortex is very distinet, may easily be peeled off from the 
soft choanosome. The skeleton agrees very well with that of the 
type. There are rather few dichotriaenes, the tetractines mostly being 
orthotriaenes of the same size and situated in the same manner as 
the former. As the two spicula-forms may substitute one another 
in the same individual, and none of them are very numerous, I 
see no necessity for laying any stress upon this divergence from 
the type as being of any taxonomic value. The oxea only attain 
a length of ca. 1000 y and there are all intermediate stages be- 
tween these and the small ones of ca. 25 some of them have 
the apex narrowly constricted. The tylasters are here about 12— 
\A y \n total diameter. Some styli of about 800 y oceur; they 
are mostly a little pathologic in structure, f. i. exhibit beginnings 
to twin structures.

Slipper Isl. The coast, at low-water. 20/XII.1914. 
Two specimens of somewhat irregularly subspherical outline, 
attached with a broad base to a stone. The structure agrees pretty 
well with that of the type. The spicule-measurements are: Di¬ 
chotriaenes 2000—3000 y, anatriaenes and protriaenes 4000 — 
5000 //; oxea 2000—3000 //; cortical oxea about 250 ^ ; sterr-
