long; interpolypar distance more than 1.5 mm. At the base of the colony the polyps are so 
very large (fig. 226) that the spines cannot project through them, although the spines are long

( 3 00 l J - and 120 [J.). The polyps are always arranged in a single series; young polyps occur between 
the adult ones. — The spines are arranged in six longitudinal rows and a straight quincunx; 
mutual distance 450 The long ones are slightly distally inclined, 
cylindrical, with broadened base; surface entirely granulated; apex 
very rough. The short spines are more distally inclined, with a very 
slightly granulated, blunt top and a smooth base, concave distal side, 
convex proximal side (fig. 225). 
The fourth specimen has its natural base and is entirely covered 
with violet polyps. Height 5 cm.; it consists of 3.5 sinistrorsal spiral coils, 
the diameter of which increases towards the colony-top, to 2.5 cm. Basal 
diameter of the axis: 0.5 mm., diminishing gradually; top is acute, through a sudden diminuition 
in diameter. Spines as in fig. 225; in the toppart they are somewhat 
more distally inclined. The polyps on the basal part of the colony are 
like fig. 226 and 227 but with their tentacles somewhat more outwards 
curved. Some of the polyps on the higher part of the colony are more 
like figs. 217, 220, 221. They are everywhere inserted in a single series! 
The oral cone is not striped, although the 
type of polyp is also often like figs. 231, 232. 
The spines are visible through the parts of 
the polyps; on some parts of the axis a 
cross-groove is visible between the polyps. 
Interpolypar distance 1.25 mm. 
The fifth specimen of station 310 has 
5 a / 4 sinistrorsal spiral coils, with diameters of 
— 2 cm. and a distance of 1 cm. or more. The basal diameter of the 
axis is 1 mm., which diminishes to 0.6 mm. at the top; after 3 / 4 coil 
the diameter shows a sudden diminuition. The spines are like those of the other specimens; on 
the basal part the longer ones are thick, short and wartlike, knobby, with a flat, blunt apex;
