considered as of importance in distinguishing the genus Metalcyonium. 
Large ova are present in the gastral cavities. Large spicules are very 
thickly distributed in the superficial coenenchyme of the stalk and 
polyp- bearing part. 
The spicules are mostly long, white spindles or rods with large processes 
on all sides, but there are also club-like forms. The spicules project in a 
marked manner from the surface, more especially from the calyx ; they also 
form a very thick layer on the surface of the stalk. 
The longer spindles and rods of the cortex of the stalk are about 2*08 
mm. in length by O'lO mm. in diameter, the shorter about 0'80 X 0*04 mm. 
The spicules of the tentacular part of the polyp are similar to the last in 
shape, but are smaller, such as 0*4 x 0"3 mm. The spicules of the calyces 
and of the coenenchyme between the polyps are fairly similar to those in the 
outer part of the stalk. The spicules from the interior of the polyp-bearing 
part are also fairly similar ; some are 0*80 x O'lO mm. These spicules are so 
long and fragile that they are very apt to become broken while being 
mounted. Spicules are more abundant in the interior of the stalk than in 
that of the polyp-bearing part ; some of the former are as much as 2-3 mm. 
in length, and I have named the species from these long lance-like spicules 
placed longitudinally or obliquely, more especially in the interior of the 
stalk. 
Many points in this specimen are similar to those of Simdaria unilobata, 
but the arming of the polyps with spicules is conspicuously different. It is 
apparently a species of Metalcyonium according to Kiikenthal's diagnosis of 
this genus. It shows some affinities with Metalcyonium clavatum, Pfeffer, 
but differs from it in the arrangement of the spicules and in other points.
