expanding toward the end, and are crowded equally over the 
whole surface; they are covered with large, conspicuous, acute 
spicula, which are grouped at summit into eight sharp project- 
ing points. The coenenchyma is thin, translucent, yellowish, 
filled with long, slender, fusiform, acute spicula. 
Height (base absent), 40 inches; diameter of trunk, without 
cells, ‘28; length of cells, ‘20; diameter, ‘08; calcareous joints 
of stem, 2 to 2°5; flexible ones, ‘15 to 18. One branch is 27 
inches long, without dividing. With this, five additional speci- 
mens of Acanella Normani were taken. 
Flabellum Goode, sp. nov. 
: fine large species with a long, deep, compressed calicle, 
its longer diameter being nearly three times as great as the 
shorter. In a side view the summit is broadly rounded and 
the lateral edges form an angle of about 144°; they are formed © 
y prominent acute coste, while the principal lateral coste are 
large, elevated, obtuse and irregularly roughened by numerous, 
obliquely ascending, raised lines, arranged in chevrons. There 
are eleven principal costs on each side, making twenty-four in 
all, each of which corresponds to one large and two small 
septa; a small ridge, corresponding to the latter, is often seen 
on either side of the large costal ridges; alternating with the 
latter there are similar, but much smaller, secondary costz. 
All the costae become fainter toward the base, which terminates 
in a tapering subacute pedicle. Wall very thin, with a glossy 
and fourth cycles successively much narrower, those of the 
third with the summits much less elevated, while those of the 
ast cycle rise nearly as high as the primaries, but are very 
much narrowed. Lateral surfaces of septa are smooth, but 
show lines of growth. 
Height, 58™; along lateral edges, 42; length of calicle, 70; 
breadth, 26 ; space between inner edges of large septa, 5 to 
8™™. Color, light yellowish brown when fresh. 
._ Vne living specimen from the eastern slope of George’s Bank, 
in about 220 fathoms (schooner Alice G. Wonson). 
Lophohelia prolifera Edw. and Haime. 
A fragment of a large, dead, but nearly fresh, specimen of 
this coral, taken about t irty-nine miles S.S.W. from the N.W.
