Sub-Order HOLAXONIA. 
Family Plexauridae. 
Genus Euplexaura. 
i. Euplexaura robzzsta Kukenthal.

A grey-brown fragment, 3 cm. in length with a stem diameter of 3 mm., agrees closely 
with Kukenthal’s description and figures of Euplexaura robzzsta. Thus the polyps show low 
but well-defined calyces with an 8-lobed margin, and a crown of three transverse rows bearing 
eight triangular points with 3—4 pairs of spindles converging in chevron. Beyond the tips of 
these triangles are seen the well-armoured retracted tentacles, as described by Broch (Svenska Akad. 
Handl. LI I, 1916) for E. flabellata , which we agree with Kukenthal in regarding as synonymous. 
Previously recorded from littoral region of N. W. Australia and Japan. 
Genus Paraplexaura. 
1. Paraplexaura verrucosa (Brundin). 
For description see: BRUNDIN, Alcyonarien Zool. Mus. Upsala. Bihang Svenska Akad. 1896,

Stat. 164. i°42'.5 S., i30°47 / .5 E. 32 M. Sand, small stones and shells. 1 Ex. 
A yellowish basal fragment of a colony shows the characteristic Plexaurid spicules, 
namely foliaceous clubs with warty divaricate base. Most of the folia have an entire margin, 
but some show strong ridges on the folium, and these may pass into folia with multiple points. 
A suppression of the foliar part and an expansion of the base gives rise to warty multiradiate 
plates. There are also many warty spindles. The axis is very slightly calcareous. 
Nutting notes that his Echinogorgia flora might be referred to the Plexaurids were it 
not that its axis is devoid of calcareous matter. But Plexaurids vary in this respect, and the 
spicule figured (Plate XXI, 10) is very definitely Plexaurid and like the foliaceous clubs of our 
specimen, which came from the same locality. 
Previously recorded from Hirudo Strait, Japan. 
Family Muriceidae. 
Genus Menacella. 
1. Menacella reticularis Gray. 
Stat. 164. i 0 42'.5 S., i30°47 / .5 E. 32 M. Sand, small stones and shells. 2 Ex. 
To the not very satisfactory genus Menacella we refer two fragments of a greyish white 
colour from Station 164. One specimen bears two branches and its total height is 9.7 cm. The 
other is unbranched and has a length of 1 1 cm. The average diameter is 2 mm.
