A small pinkish colony from Station 31 5 shows tentacles with on each side two rows 
of 12 pinnules in each row. 
A withered colony from Station 152, shows shrivelled polyps, up to 1 cm. long, with 
tentacles bearing on each side two rows of pinnules, about 12 in each row. 
Previously recorded from the Red Sea.

A badly preserved but interesting yellowish-grey specimen from Station 104, Sulu, agrees 
with Anthelia ternatana (Schenk) in the following respects: 
( a ) From a membranous basis there spring very long polyps, up to 41 mm. in length, without 
including the tentacles. 
( b ) the tentacles are narrow and very long (up to 22 mm.). 
( c ) the surface of the polyp is densely covered with minute rodlets, lying in various directions. 
(d) the spicules are uniform, minute rodlets (0.06 X 0.01 mm.), somewhat like finger-biscuits, 
with ends rounded or blunt, the surface covered with minute roughnesses. 
Several groups from Station 64, Djampea seem to us referable to this species, but the 
pinnules are not more than 30 on each side, and sometimes only half that number. We are 
convinced that the number of pinnules within certain limits is mainly an age or growth character. 
The polyps in the specimens from Station 64 arise from a membranous expansion to a 
height of 15 — 30 mm.-, the tentacles are usually 5 — 8 mm. in length; the walls of the polyps 
are rather thin ; there is very little contraction in any of the specimens ; the colour is very light 
brown. We should compare the spicules to superficially roughened finger biscuits, and they are 
very like those figured by Schenk for CL ternatana. Average dimensions are 0.04 X 0 - 01 mm. 
A whitish grey colony, from Station 81, with crowded substantial polyps, often inflated, 
in many cases 10—15 mm. in height, rising from an encrusting membrane. One of the distinctive 
features is the dusting of the surface with very numerous rodlet spicules, about 0.06 X °- 1 5 mm., 
with a surface bearing minute asperities. The uncontracted polyps bear long tentacles with 3 — 4 
rows of long slender pinnules, about a score in a row. The appearance of polyps and tentacles 
varies greatly, of course, according to the state of contraction. 
Another cluster from Station 64 shows the same rodlet, slightly roughened spicules, 
thickly dusted over the surface, and the characteristic lank tentacles with numerous long pinnules, 
but they number only 24 on each side, which shows, we think, that the number of pinnules is 
relatively unimportant. 
In some fine colonies growing on a mass of sponge from Station 93, Sanguisiapo Reef, 
the long flaccid polyps up to 41 mm. in length arise from the encrusting basal membrane.
