about 560 jti; thickness about 27 2. Sigmata (fig. 6b), very 
regularly curved, seldom contorted, delicate, the apices rather abruptly 
inwardly curved; 10—18//^ from curvature to curvature, thickness 
1 3. Toxa (fig. 6c), elegantly arrowshaped, rather sharply bent 
in the middle, apices a little recurved; ca. 55 jn.

Little Barrier Island. 30 fathoms. Shell-bottom. 29/XII.1914. 
Colville Channel. 35 fathoms. Sand, mud. 21/XII.1914. (The type). 
Three specimens. 
Typically barrelshaped; in all specimens several barreis are, by 
a budding-process, issuing from the more or less lump-shaped 
specimen ca. 70 mm in its greatest extension; the 
barreis up to ca. 35X18 mm, all bearing an oscu- 
lum at the top; oscula from 1 to 5 mm in diameter; 
the numerous subdermal cavities are seen as dark 
spots through the dermal-membrane; they are up 
to 1 mm in diameter, giving the sponge a charac- 
teristic appearance. Texture tough, elastic. Colour 
dark, with a reddish tint. 
The skeleton is a coarse network of stout spicula- 
fibres and spicula-lamelles, i. e. broad flat fibres; the 
spicules are lying very densely, and cemented to- 
gether by a little amount of very pale inconspicuous 
spongin; the network is very irregular; the meshes, 
or rather the interstices between the fibres, are up to 
ca. 600 y in diameter; primary and secondary fibres 
cannot be distinguished; the fibres and lamelles are up to ca. 400 
thick; they reach the dermal-membrane perpendicularly as well 
as obliquely at any angle. Everywhere in the choanosome spicules 
are scattered, both strongyla and sigmata. The dermal-membrane is 
sustained by autogenetic spicules lying tangentially, as well as by 
imbedded foreign particles; also the fibres and choanosome contain 
foreign matter. 
Spicules. 1. Strongyla (fig. 7 a), straight or slightly curved, 
cylindrical, with evenly rounded ends; 170—190X6 — 8 /«. 2. Sig¬ 
mata (fig. 7 b), very numerous, often contorted, 10—20X1 /f. 
basis; largest
