some parts of the colony the tentacles are crowded in a distally directed group, covering the 
oral cone (fig. 239). I he sagittal tentacles are always inserted at a lower level than the lateral 
ones. The oral cone, less conspicuous than in the preceding 
specimens, also shows a like number of vertical stripes (fig. 237); 
the mouth is round but not always sharply defined. — The base 
of the tentacles is often leadblue in colour. 
1 he specimen of station 156, without polyps, is 12 cm. long, 
and consists ol two straight parts of 8 and 4 cm., connected at right

on a height of 4 cm. a sudden diminuition of the diameter to 
5 75 P- takes place. I he spines at the base of the colony are 450 and 150 p. long on opposite 
sides of the axis, with a mutual distance of 375— 450 pt. There are no longitudinal rows or 
other regularities. Some spines are doubled over a great part of their length. The long ones 
are inserted at right angles with the axis; the shorter ones are slightly distally inclined. Their 
apex is very rough, knobby (fig. 240«). On the higher parts of the colony this roughness 
increases (fig. 240^). On the toppart of the colony the spines are more slender (fig. 241 c), their

length lemains equal, and the distribution is entirely irregular. I he long spines here are slightly 
distally inclined. Doubled spines occur (fig. 241 ff). On some higher parts there are 6 regular

The characters of the specimens under discussion I have reviewed in the tabel on p. 165, 
which demonstrates that all these specimens, however divergent they may be in some points, 
appertain to one and the same species. While in the number of longitudinal rows, the shape of 
the spines, and the further characters of the spines no conspicuous differences are to be seen, 
the second and third column give rather divergent data; as to the length: for the longest spines 
iiom 225 530 p, for the shorter spines from o—225 p., and as to their mutual distance from 
45 ° 75 ° [ J - Usually the spines are covered with fine granulations, except the top which is 
covered with rough knobs; in one case the spines are almost smooth with rare knobs. Usually 
the spines are ot different length on opposite sides of the axis, except with V where long and 
.-Tort spines are intermixed, which is a proof that this character is of no specific value, wherefore
