base of one of the colonies a Lepadide is fixed, which for a large part is covered with coenen- 
ch) ma and polyps (as fai as the dotted line in the figure). I he polyps on this covering are not 
entirely normal; sometimes only a tentacle, sometimes a large crowded group of tentacles is 
seen, without it being possible to make out with certainty how many polyps make this group. 
I think it worth noting that the coenenchyma has covered a foreign object, which character is 
the same as the typical quality of the subtribe of the Crustosae ! — On that part of the colony 
which follows distally after the Lepadide, the polyps are over a distance of i cm. more crowded 
than usually; their interpolypar distance is max. 0.75 mm. 1 ).

This large group contains 35 specimens, which only in a few cases are fragments of 
a colony. A sinistrorsal spiral stem is found with 10 specimens; 6 colonies are partly spirally 
wound, partly irregularly curved, while the other specimens (19) are all of them irregularly 
curved or sinuous, without showing a spiral coil or even part of a spiral anywhere. With 23 
specimens the diameter, which is max. 300 y. at the broken base, increases at first towards 
the top, which is slender. The length of the colony is max. 21 cm. A suddenly diminishing 
diameter also occurs, with a change in the type of spines; sometimes large parts of the 
colonies are of subequal diameter. 
The spines are arranged in 6 longitudinal rows, and in some specimens this number 
diminishes to 4 on part of the colony, but never on the entire colony; however there are 
specimens which have 5 or 7 rows on the entire colony. The rows alternate in a quincunx, 
but on some parts they are at an irregular level with respect to each other. — The length 
of the spines is from 75 to 315 y. for the long spines and 45 to 200 y. for the short spines. 
Their mutual distance is 315 to 560 y„, but mostly 450 y„ while 
the greatest distance is often found with the longest spines. —- The 
shape of the spines is not variable to such a degree as in var. 
aspenspina. Pour fifth of the number of colonies have the type of 
spines of fig. 164 a on the entire colony or on its greatest part. 
These spines are long, slender, smooth, distally inclined, with a 
convex proximal side and a concave distal side. Sometimes the base 
is somewhat more elongated than in the figure, and the apex may be Sp ines: a on the base of a colony; 
more acute. On the base of the colony the spines are triang-ular h 4 cm * hlgher ’ c near the t0 P>

with their distal side at right angles with the axis (fig. 164 6 ) and some 
fragments are entirely covered with this type, which may also have a more blunt apex (fig. 165). 
The smoothness of the spines is no universal character in this group, for a few spines of a

covered with a thin horny layer bearing numerous little spines. — Thomson and Simpson in the description of Antipathella rugosa T. & S. 
make the following remark: “the colony bears numerous epizoic animals:- — Cirriped galls and stalked barnacles, tubes of Spii-orbis , several 
Polyzoa, a sponge, and a young pearl oyster shell. It is worthy of note that tha majority of these are overgrown by the coenenchyma 
and bear both polyps and spines.”
