like fig. 128, with an interpolypar distance of 1.25 — 1.5 mm. Sagittal tentacles 0.75--1 mm., 
lateral ones 0.75 mm. One of the colonies has polyps (fig. 148) with knobshaped, shorter 
tentacles, 0.22 mm. long.

Two of these colonies are partly wound in a spiral, while the other two are irregularly 
sinuous. All 4 specimens show the increasing diameter in their basal part, and the other 
characteristics, also the abnormal ones, of the general type. Two colonies have a complete base 
with basal plate, which is round, darkbrown, with a diameter of 165 p., and surrounded by a light- 
yellow border, 65 p, broad; the basal diameter of the axis is 450 p. and increases to 600 p.. — 
There are 7 longitudinal rows of spines, sometimes diminishing to 6 rows; in one colony there 
are everywhere 8 rows. The length of the spines is 105 — 155 p. for the long ones, 55—90 p. 
for the short ones on the opposite side of the axis. The mutual distance is 375 — 525 p.. Usually 
they have the normal type of fig. n6«, but they may be more upright on the axis. One of 
the colonies has spines of the type of fig. 123, which however also occurs twice among the 
deviations of the great group. The polyps are like fig. 138, but the tentacles may be somewhat 
shorter; the diameter of the oral cone is 200 p. ; the interpolypar distance is 1.3 mm.

Three of the four specimens have a stem, wound in a sinistrorsal spiral, while the fourth 
specimen is a fragment of too short a length to make out the shape of the stem. All of them 
have the normal characteristics of the stem. The spines are arranged in 7 longitudinal rows, 
sometimes increasing to 8, and in one colony always 6 in number. The shape of the spines

(figs. 149a and 150) agrees with the general type or its deviations; sometimes the spines have 
a smooth surface (fig. 149^). The long spines are 80 — 120 p., the short spines 70—75 p. ; their 
mutual distance is 375—480 p.. The polyps, at an interpolypar distance of 1.5 mm., have the 
type of fig. 15 1, very much like figs. 130 and 137, while their profile is very much like fig. 134.

This colony is wound in a dextrorsal spiral, with a complete base, fixed on an irregular 
round plate, 3.5 mm. in diameter and the border of which is 0.5 mm. wide and lightbrown. 
The basal diameter of 760 p. diminishes gradually towards the top. The spines are arranged 
in 8 to 9 longitudinal rows, which number diminishes to 6 in the higher parts of the colony;
