directions, there being no regularity whatever. The collaret is dis- 
tinct, formed of annularly disposed spicules. The opercular spicules 
are in bundles of a dozen or more, parallel and vertical, rather short 
with blunt ends, arranged en chevron at the very bases of the tenta- 
cles. Spicules of the cortex with a tendency toward a longitudinal 
arrangement, although there is much irregularity in their disposition. 
Color.—The axis, cortex, and calyces are all creamy white in color 
(in alcohol), so that the colony bears a striking resemblance to a 
coral, |

CLEMATISSA TENUE, new species. 
Plate XLIV, fig. 3; plate XLIX, fig. 2. 
Colony straggling in habit, attaining a height of 150 mm., some- 
times unbranched and at angie very sparsely branched. In one 
specimen there are two very ‘short branches very distant from each 
other, and in others there are several long, straggling, irregularly dis- 
posed branches. 
Calyces arranged in rather irregular spirals which grow closer 
_ toward the distal ends of the branches. Branches terminating in a 
polyp. The calyces are very low dome-shaped, spreading at their 
bases, which are often contingent. 
Polyps, when expanded, arising abruptly from the summit of the 
calyx, where they assume the form of a miniature acorn; sometimes 
the polyp is greatly elongated and the tentacles are extended and not 
folded over the mouth as usual, but generally the attitude is the char- 
acteristic one of the family. The expanded polyp shows eight longi- 
tudinal bands of warty spicules. | 
Spicules usually small, exceedingly varied in shape. Those of the 
coenenchyma are almost scale-like in appearance, and their outer edges 
seem to overlap the inner edges of those in the next row; edges jagged 
and irregular. The spicules of the calyx walls are similar to those 
just described. The collaret is evident, the spicules at the bases of 
the tentacles are warty spindles arranged en chevron, and the re- 
mainder of the tentacular spicules are longitudinally arranged. There 
are many warty spindles in the cortex, often with projections on one 
side, sometimes curved or branched.
