are shaped as in fig. 177 a, so almost the same as in station 318, but sometimes sinuous. 
There are 5 longitudinal rows of spines, sometimes increasing to 6; the long spines are 
285 —345 l J -> the short ones 165—210 p; their mutual distance is 600—750 p. On the higher 
parts of the colonies, as well as on the extreme basal part, the type of spines is as indicated 
in fig. 177 b, c, d, smooth or sligthly granulated at the top of the spines. Sometimes the young

spines have more than one apex. — The polyps and the coenenchyma are very transparent, 
so that the ova may be visible through the body wall (fig. 178«) and they are lifted very 
high by the spines. The tentacles are short and thick (fig. 178 a) or, as an exception, long 
and slender (fig. 178^). Especially the last type agrees very well with the type of polyp of the 
great Saleyer-group. The sagittal tentacles are 0.45 — 0.65 mm., the lateral ones 0.27—0.4 mm. 
The interpolypar distance is large, viz. 2 mm.

This colony is irregularly curved, and 16 cm. long. The 
spines are arranged in 5 longitudinal rows, alternating in a 
quincunx; they are 270 p and 195 p long, at a mutual distance 
of 450—750 p. Their shape (fig. 179) is very much like the 
general type of this variety, especially fig. 179 <?, but they are 
distally inclined to a smaller degree, while their base is much 
longer. — Since on large parts of the colony spines of the type 
of fig. 179^ and b are present, which have an entirely smooth 
surface, but at the same time are rather long, this specimen is 
a transition towards the sub-var. lissispina of this var. The 
polyps are badly preservated, but the rests, which are visible (fig. 180) have very long thin 
tentacles, very transparent just like the coenenchyma. They 
are very low, and their type may be compared to figs.

This colony is of the normal type, wound in a spiral. There are 5 longitudinal rows
