contain warty spindles up to 1.3 mm. long, with extraordinary, almost rod-like outgrowths, up 
to 0.2 mm., arising at right angles or an acute angle to the main axis (Plate XXVII, Fig. 2). 
There are also smoother spindles and triradiates with simple prominences. The branched spindles 
of the canal walls agree with the description of those in the upper rind of X. robusta.

A vigorous flaccid colony of a brownish-madder to grey-cream colour has a height of 
9.6 cm. and a spread of 12.5 cm. Numerous branches arise from a very short common stem, 
and bear conical lappets terminally rounded-off. 
We have referred it to N. thujaria for the following reasons: (1) the polyp armature 
consists of indistinct double rows, about six in a row; (2) the polyp head is bent down at an 
acute angle; (3) the supporting bundle is strong, of the ensheathing type, and does not project; 
(4) the polyp spindles are marked by prominent long thorns, usually simple; (5) the cortical 
spicules are densely thorny spindles, sometimes cylinders, sometimes with compound roughnesses ; 
(6) the canal wall spicules are massive spindles with numerous strong thorns. 
It must be noted, however, (1) that the massive spindles are sometimes triradiate and 
(2) that the lower cortex includes small irregular spicules which may be evolved from the irregular 
branching of a simple capstan or two-headed-rodlet type. These two forms are not included in 
Kukenthal’s description of his specimens.

A light brown colony from Station 144 (45 m.), with roundish to conical lobes thickly 
beset with polyps, showing a distinct supporting bundle hardly projecting. The total height of 
the colony is 4 cm., of which 1.4 cm. belongs to a common base, this again dividing into two 
sterile trunks 1.5 cm. in height. The characters correspond on the whole with Kukenthal’s 
description, noteworthy being the strong compound tubercles which arise from many of the 
spindles and are often much higher on one side than on the other, especially on the curved 
forms. A common length for the long thorny spindles is 1.4 mm.
