(3) very abundant on the cortex, short-stalked and long-stalked clubs, with upward pointing proces¬ 
ses at the thick outer end, and sometimes with warts on the shaft, 0.3 X 0.04: 0.12 X 0.02 mm.; 
(4) delicate narrow spindles, with distant warts. They are both straight and curved, 0.63 X 
0.05 mm.; 
(5) a few crosses 0.1 X 0.08 mm. 
The short-stalked clubs begin as very simple forms, slightly dentate at the expanded end, 
and with two minute prominences near the base of the handle. With increase in size the club 
end becomes markedly knobbed, and a few more prominences develop at the end of the handle. 
On a slightly different line are the long-stalked clubs, marked by the frequent irregularity 
of the less differentiated club end, and by the common twisting of the long stalk, which may 
also bear small warts. 
A fine brownish colony from Station 315 has a total height of 7.7 cm., of which 3 cm. 
belongs to the unbranched trunk. This divides into several upright thick branches which give 
rise to the rather short blunt twigs (average diameter 4 mm.) where the retracted zooids are 
most numerous. The dimensions of the longest twig were 7 mm. X 4 mm. The branches and 
twigs are slightly flexible and somewhat brittle. This type bears a close resemblance to 
Burchardt’s figure. The average distance between two autozooids on the twigs is about 1 mm. 
A colony from Saleyer, 4.7 cm. in height, has twigs with an average diameter of 5 mm. 
and a maximum length of 1.3 cm. 
Cream-coloured colonies from Amboina show a more slender and conical type of twig, 
with an average diameter of about 3 mm. 
A rather withered brown colony from Haingsisi, with a height of 8 cm., would seem to 
have grown in sand to a depth of 3.1 cm., with in addition a disc of attachment (4.2 X 2.4 cm.) 
at the side of the stem, which had probably adhered to rock or coral. 
Of various colonies from Tual some are very withered with thin flattened branches. 
A large specimen from Station 213, Saleyer, 8.3 cm. high, with a deep brown stem and 
cream-coloured twigs, shows a stout rounded stem, 3.5 cm. in diameter, dividing after about 
4 cm. into several upright parallel branches which bear a large number of small twigs, many of 
them simply small rounded lobes only 1 mm. high, none exceeding 7 mm. in length, with an 
average diameter of 2 mm. The spiculation is identical with that of the more typical specimens. 
Another fine colony, 8.4 cm. high, from the same station shows a similar type of growth. The 
diameters of the stem are 7.8 and 3.2 cm. Similar much smaller colonies from Stations 142, 
240 and 301. 
A puzzling shrivelled white colony from Station 123 bears a strong superficial resemblance 
to S. querciformis , which was also collected at that station. It is 3.8 cm. in height, of which 
2 cm. is the rather slender stalk. The twigs are mostly elongated and narrow, up to 1.1 cm. 
in length and 3 mm. in breadth, with the polyps all in a state of retraction and situated about 
1 mm. apart. In spite of the external resemblance to S’, querciformis , the cortical clubs are 
very much smaller, and are markedly different in shape from those of that species, the whole 
spiculation agreeing with that of S', leptoclados. 
A colony (locality unrecorded), with a height of 6 cm., shows branching and spiculation 
agreeing most nearly with this species, but the twigs are slightly less brittle and hard in texture.
