the short ones are slender. On half of the colony-height the long spines are 240 u. while the 
opposite side of the axis is entirely smooth. The spines are arranged in longitudinal rows 
without further regularity, since the mutual distance is rather variable (max. 675 y.). The top 
of the colony bears spines like fig. 225, especially as to the short spines; here are 6 longitudinal 
rows, alternating in a quincunx. No polyps. 
The last specimen is 9 cm. high, with 7.5 sinistrorsal spiral coils, with 
increasing diameter (2—2.5 cm.; distance 1 —1.5 cm.). The first 2.5 coils are 
followed by a. sinuous part of 3 cm., before the other coils are formed. The 
basal diameter of nearly 1 mm. tapers gradually and is 
0.5 mm. at 0.5 cm. distance from the top, which is blunt. — 
There are max. 8 longitudinal rows of spines (sometimes 
6 — 7), alternating in a quincunx (fig. 228). Length of the 
spines 225 y. and 150 y.. Mutual distance 500—600 y.. The 
Fig. 22S. Eucirripathcs longest spines are situated on the polyp-bearing side, the 
spiralis(Bla'mw.) v.Pesch. 
Arrangement of the distal side of the coils. The long spines (fig. 230) are blunt 
spines, on the middle of con j ca i a t right angles -with the axis or slightly distally 
inclined; the small ones are triangular, sharp or blunt (fig. 229) 
and more distally inclined. Towards the top of the colony the spines are more distally inclined, 
towards the base more upright. They project through the polyps. Surface slightly granulated 
or smooth; apex sometimes but rarely roughly knobby, especially at the colony-base, where 
one spine is even doubled.

The polyps (figs. 231, 232) are leadblue; the top of the tentacles is-much lighter, yellow- 
white with brown wrinkles. The oral cone is white with 10 leadblue or brownish, vertical stripes 
which are situated between a same number of swellings (fig. 233). The interpolypar distance is
