Spine; 58.5 X- 
spines is 450 ix, which value is variable. The shape (fig. 203) is thick and cylindrical with a conical 
blunt apex; usually they are at right angles with the axis, but they may be 
also somewhat distally inclined; their surface is granulated. The average 
length is 180 u. and there is no very conspicuous difference in length on 
opposite sides of the axis. The polyps (figs. 204, 205 and PI. VIII fig. 7) 
are situated in a great number at every side of the axis, except for a 
tract on one side of the axis, somewhat broader than the normal distance 
between the polyps. They are arranged in longitudinal rows, which now and then become 
irregular. The interpolypar distance varies rather much and is max. 2.2 mm.; 
however often two polyps are so near each other as to touch their mutual 
bases. Some younger polyps are inserted between the adult polyps in an 
irregular way. The sagittal tentacles are 2.3 mm. long, the lateral ones

lateral ones. I he oral cone is very high with a basal constriction and a 
flat upper side, which has a sagittally elongated slitdike mouth. The diameter of the oral cone 
is 0.5 mm., its height is 0.5— 0.6 mm. — Between the 
polyps the cross-grooves in the coenenchyma may be 
clearly seen together with a great number of very fine 
grooves or canals, which alternately converge and diverge, 
since they surround the base of the polyp (fig. 205 at 
both ends of the fragment). With a view upon the remar¬ 
kable qualities of the stem I shall describe the dried 
specimens separately : 
I. 0.5 m. long; diameter 3.5—4 mm., with swellings at 
irregular places; the entire colony is irregularly sinuous, 
without a trace of a spiral, but the principal direction 
is straight. Most of the curves are accompanied by 
angular bends of the axis. The colony-top, which is 
complete, as is demonstrated by the coenenchyma, which 
covers it undamaged, has a very typical shape (PI. VIII, 
fig. 4): its diameter increases swiftly to 6 mm., while 
the entire top is covered with little knobs. — On two 
places the colony has a kind of branch; one of them 
is a conical knob of only 3 mm. high ; the other one, 
3 dm. further on, is an unmistakable branch of 1.5 cm.
