and figures. The spicules are (a) almost smooth delicate rods from the interior, (l) the same 
type with sparse conspicuous prominences, (c) numerous more substantial spindles with high 
simple warts, (d) forms derived from the spindle type with irregular jagged prominences. Some 
of the warty spindles are straight, other slightly curved. No crosses or the like were to be 
seen, but the fragments are very small. 
To Studer’s description must be added the fact that the polyps show very distinct 
crown and points. The crown shows about three horizontal rows of spindles. Each point is made 
up of two or three pairs of sloping spindles. The verrucse are prominent and blunt, with 8 
prominences round the margin.

Stat. 122. i° 58 / .5N., i25°o / .5 E. 1264 — 1165 M. Stone. 1 Ex. 
A fragment of a main stem, 2.5 cm. in height, giving off a branch 3 cm. long. The 
diameter of the broken stem is 4 mm. It agrees thoroughly with Nutting’s description, except 
that the spindles include relatively broad and flat rough forms, some swollen at one end in 
pseudo-club fashion. We would add to the ^description of the anthocodial armature that there is 
a collaret of about six horizontal rows and above that eight groups of chevroned paired spicules, 
ending in points above the base of the tentacles. 
Previously recorded by Nutting from the same Malayan Station, 1264—1165 metres.
