(c) very slender straight or slightly curved spindles, smooth or with comparatively few very 
minute simple prominences. They are pink in colour. The measurements of the largest of 
these to be seen were 0.5 X 0.02 mm.

A luxuriant, much branched, flaccid colony of a yellowish colour, with a total height 
of 17 cm. Numerous branches arise simultaneously from the top of a short basal portion which 
is about 1 cm. in height. The breadth of this stalk at the top from which the branches diverge 
is about 5 cm. 
The features of the species are (i) the elongated narrow catkin-like lappets, which attain 
a length of 2 cm., (2) the absence of spicules from the polyps, (3) the numerous irregular micro- 
sclerites of which many are jagged interlocking rodlets with relatively long prominences. There 
are also a few spindles with long abruptly projecting prominences. There are numerous yellowish 
warty bodies, somewhat like double spheres, but they are certainly extrinsic sancl-grains. The 
canal walls contain long warty spindles, often with a bend and a cross line across the middle. 
Intermediate between these large spindles and the micro-scleres there are straight or slightly 
curved spindles irregularly covered with low roughnesses. This specimen agrees well with May's 
description of Lithophytum sanderi , but Kukenthal’s reinvestigation showed abundant spiculation 
of the polyps.

A yellowish brown colony, from Station 248, rising to a height of 9.5 cm., with a 
spread of 8.5 cm. A massive short stem gives off numerous branches, which rebranch and end 
in crowded conical lappets. These are entirely covered with polyps. There are no spicules in 
the polyps or on the cortex of the branches. The cortex of the stem shows numerous irregular 
jagged bodies, many of the capstan type, and including some which may be described as 
double stars, as in L. shihlmanni. In the interior of the stem there are stout spindles covered
