The tentacles attain a length of io mm. and show approximately 45 slender pinnules, in a single 
row on each side of a fully expanded tentacle. 
The characteristic features of A. ternatana are the following ; 
(a) the notable length of the polyps and tentacles; 
( b ) the abundance of superficially roughened rodlets; 
(y) the shallow longitudinal grooves of the polyp-body, which is more delicate and flaccid than 
in most species. 
Perhaps A. garcice and A. glciuca are the most nearly related species, and it must be 
emphasised that the specific characters in this genus are very variable.

4. Anthelia simplex n. sp. (Plate XIV, Fig. 4). 
Stat. 240. Banda. 9—45 M. Black sand. Coral. Lithothamnion-bank in 18—36 M. 1 Ex. 
This interesting form is represented by a single polyp rising from a thick membranous 
base to a height of 2.6 cm. not including the tentacles, the longest of which are 8 mm. in length. 
It is a clear Anthelia without any calyx. 
Its distinctive features are the following: 
o 
(a) the pinnules are very simple and short, like those described by Hickson for Stereosoma 
celebense ; 
( b ) they occur in a single row, in four tentacles six in a row, while in the other four larger 
ones there are twelve; 
( c ) the tentacles with twelve pairs of pinnules are fully twice as long as the short ones; 
( d ) the long ones are adjacent to one another, and so with the short ones; 
( e ) the body of the polyp shows vague longitudinal lines; the mouth appears as a longitudinal 
slit on the top of a short hypostome; 
(f) the whole surface of tentacles, body, and base is studded with minute blunt-ended rodlets, 
among which there are many sandy particles; under high magnification the rodlets appear 
slightly granular; 
(g) the dimensions of the rodlets are about 0.06 mm. in length by 0.015 mm. in breadth. 
In many respects the specimen is very like Stereosoma celebense , which was however 
without spicules.
