One of the specimens is 70 cm. long and lacks the natural base; the entire colony is 
wound in a sinistrorsal spiral, wherefrom three coils are visible, with a diameter of 15 cm. and 
a mutual distance of 7 cm. between the coils. The height of the colony is 30 cm. ; the basal 
diameter is 3.75 mm. and diminishes regularly towards 
the rather slender top, which on 5 cm. distance from the 
apex has a diameter of 1 mm. The spines are triangular 
or cylindrical and blunt; they are distally inclined. Their 
length is somewhat greater at the polyp-bearing side of 
the axis, viz. 150 4, but interspersed between the larger 
ones many smaller spines occur. Their mutual distance is 
rather variable, as is shown in fig. 107, where they per¬ 
forate the coenenchyma; the average distance is 530 4. Usually the spines are irregularly 
distributed, in a large number, but sometimes there are traces of longitudinal rows, ± 10 at 
a rough estimate, which are rather vague. The irregularities are mainly caused by doubling 
of the spines; both members of a pair are removed at a more or less great distance from 
one another. This doubling of the spines occurs on a short distance (15 cm.) from the top, 
although the distribution is more regular here. In this part there are 6 longitudinal rows, which
