A specimen from Savu seems referable to the above species. The cauliflower-like colony 
has a maximum height of 2.2 cm. and breadth of 3.3 cm. with a basal diameter of 3 cm. The 
stem early divides into numerous upright rigid branches on the top of which are borne the 
thickly clustered polyps in flattened clumps. The polyps have dimensions agreeing more nearly 
with those described by May as Ammothea batiiana (== Lemnalia), which has been merged by 
Kukenthal into the same species. Occasionally a more pointed lappet is seen, but for the most 
part these are very low and flat, about 2 — 3 mm. high. 
The spicules include (a) small spindles from the polyps with a few simple warts towards 
the middle; average length 0.13 mm., breadth 0.015 mm.; (b) long pointed spindles with sharp 
simple prominences; dimensions up to 0.37 mm. long and 0.02 mm. broad; (c) a few bow forms 
with two exaggerated basal warts projecting, so that many show the typical Lemnalia quadri- 
radiate shape; average distance from point to point of the bow, 0.12 mm. Young forms of this 
type are seen with the points so short that a capstan-like appearance results. 
The colour is a deep cream, and the whole colony is hard and rigid, with a firm 
harsh texture. 
Previously recorded from Indian Ocean, Baui Island (near Zanzibar).

A vigorous colony, from Station 149, has a pronounced pinkish brown colour. A short stout 
base gives origin at a low level to several short branches, which soon divide into long polyp-bearing 
branchlets. The anthocodiae are prominent, but sub-sessile. The spicules are all spindles. The 
longer forms have relatively few low prominences, but there are shorter types distinctly rough. 
Somewhat rod-like minute scales, sculptured on the surface, are to be seen on the tentacles 
A strong colony from Station 142 has a creamy yellow colour and numerous fingerdike 
polyp-bearing branchlets. These unite in twos or threes into short thick branches, springing 
from the common base. In this specimen the minute spindles with two or three zones of warts 
were unusually numerous, but there is the characteristic abundance of very delicate, elongated, 
relatively smooth spindles. 
This common species, well described by Klunzinger and Reinhart, is referred by Kukenthal 
to his new genus Paralemnalia (Alcyonaria des roten Meeres, 1913, p. 16), but we are uncon-
