A limp light brown colony from Kabaena Island, consisting of a sterile stalk about 
3.5 cm. in height and 6 mm. in breadth, surmounted by three main branches with polyps in 
lappets. The total height of the colony is 6.5 cm. 
The polyps are small, about 1 mm. in height ; the supporting bundle is distinct but 
does not project far, if at all. The canal walls have numerous small spindles. 
The dorsal aspect of the polyp shows clear chevron rows of seven pairs of spindles ; 
these are reduced to about five pairs laterally and there are only a few ventrally. 
This species is in some ways near JV. hartmeyeri Kukenthal and N. coinplanatci Kiikenthal, 
but the spiculation is different, the most outstanding features being: (1) the great length of 
many of the thorns (0.06 mm.) on the straight or curved spindles, (1.4 X 0.15 mm.); (2) the 
asymmetrical development of these thorns, which predominate for instance on the convex side 
of a bow-shaped spindle; (3) the sparseness of small irregular bodies of the capstan type. 
Many of the prominences are tapering and unbranched ; others show the beginnings of three 
or four divisions, suggesting an antler. 
A rigid contracted colony from Station 49, of a light brown colour, consists of a heavily 
spiculated sterile trunk, 1.4 cm. in height and 4 mm. in diameter, and a small number of hillock- 
lappets so much contracted that the polyps are in contact. The polyp-bearing part is only 8 mm. 
in height. Superficially this appears somewhat different from the type specimen of N. cervispi- 
culosa, but the spicules are almost the same and so is the armature of the polyps. The conspi¬ 
cuous feature in the spicules is the huge size of the prominences, which are often compound, 
and sometimes suggest antlers. The supporting bundle is strong but hardly projecting ; the 
anthocodia is bent inwards almost at a right angle. 
A yellowish brown colony from Station 43, Sarassa, rising to a total height of 6 cm., of 
which 3.7 cm. go to the sterile densely spiculose stalk. The polyps are loosely disposed in 
elongated lappets. 
The supporting bundle usually projects slightly ; the polyps are bent at right angles to 
the stalk; the anthocodial armature consists of four dorsal rows of about five to six or seven 
pairs of chevron spindles. The other rows are only represented by irregular spicules. 
The spicules include the following types: 
(a) substantial slightly curved spindles, densely covered with high, very compound warts 
(1.3 X 0.2 mm.); 
ip) slender curved spindles with small conical warts, not very numerous (1.5X0.1 mm.); 
{c) curved spindles with asymmetrical compound prominences, higher on the convex side 
(1.1 X 0.15 mm.); 
(d) pseudo-clubs with very high compound prominences ; 
{e) branched or multiradiate forms, tuberculate triradiates (with 0.3 mm. to a ray), and irregular 
starfish-like types; 
(/) small irregular bodies.
