30 BULLETIN OF THE 
Stenogorgia casta VeRRILL, sp. nov. 
Plate II. Figs. 1, la, 1b. 
A small, delicate coral, pure white in alcohol, with rather prominent calicles, 
in two 5 eee rows. The base is expanded and adherent. The main stem 
divides dichotomously from near the base. The branches fork irregularly and 
unequally, or sometimes branch somewhat pinnately and sparingly. The 
branches and branchlets spread outward at a wide angle, and then curve 
upward; they lie nearly in one plane, and do not differ much in size, the ter- 
minal ones often being the largest. The axis is nearly round, chestnut-brown 
in the larger branches, pale yellowish in the terminal ones. The calicles are 
prominent verruciform, or broad-conical, and form a close row along each edge 
of the branches, but those in one row do not lie precisely in a plane, for they 
alternately fave a little to the front and to the rear; those on opposite margins 
of the branches alternate, and as the swollen bases of the calicles are in con- 
tact the edges of the branches show a zigzag outline; the calicles are narrow at 
the summit, in the preserved specimens, and are closed by eight convergent 
segments, and in most cases they are surmounted by a small round cluster of in- 
curved tentacles, which show their outer surfaces filled with convergent spicula. 
"The largest specimen is 100 mm. high, and 120 mm. broad; diameter of the 
branches, including calicles, 2.5 to 3 mm. 
The spicula of the ceenenchyma and calicles are rather small, fusiform, often 
bent, irregularly covered with more or less numerous prominent warts; some 
of these spicula are elongated and acute at both ends; others are stouter and 
more obtuse; the longer spicula measure .32 by .06, .28 by .05, .28 by .045, 
.23 by .05, .20 by .05, .16 by .03 mm.; the stouter ones, .21 by .06, .20 by .07, 
.17 by .06, .15 by .06, .11 by .045 mm. In the tentacles there are numerous 
slender, mostly bent and sparingly warted or spinulated spicula, acute at one 
or both ends, with some that are larger, blunt, and roughly warted at one end, 
and others roughly warted all over; flattened oblong spicula, some of them 
with roughly warted borders, also occur. The slender, smoothish spindles of 
the tentacles measured were .23 by .02, and .19 by .015 mm.; the stouter and 
rougher ones, .26 by .05, .26 by .03, .19 by .04, .16 by .03, .14 by .03 mm.; 
the flattened oblong ones, .10 by .05, and .10 by .04 mm.
