Taken at numerous localities in the Caribbean Sea and among the Antilles, 
in 88 to 163 fathoms, by the Blake, in 1878-79, and off Cuba, in 288 fath- 
oms, in 1880. 
Chrysogorgia Fewkesii Verritt, sp. nov. 
Chrysogorgia Desbonni PourTaxés, 1868 (non Duch. & Mich.). 
Coral tall, spirally branched, nearly as in Dasygorgia Agassizii and D. 
spiculosa, but larger and stouter, with thicker and more numerously divided 
branches; stem strongly bent in zigzag; the main branches diverge, on all 
sides, nearly at right angles, one arising from the outer side of each angle; 
distance between the branches from 4 to 6 mm. The branches fork repeat- 
edly, the first division being usually about 10 to 12 mm. from the main stem; 
subsequent divisions are at unequal distances, the final branchlets numerous, 
very small, and spreading widely. Axis smooth, hard, brownish yellow or 
amber-colored in the stem and larger branches, and with only a slight irides- 
cence; pale yellow, translucent, very slender, in the smaller branches. Ccenen- 
chyma thin, white in alcoholic specimens, composed of large, fusiform, warty 
spicula, arranged lengthwise of the branches. Calicles irregularly scattered, 
rather small, prominent, usually constricted below the middle, with the sum- 
mit and base enlarged; they mostly stand nearly at right angles to the 
branches, those near the tips obliquely ascending. Surface of the calicles 
covered with large, stout, warty, curved spicula, which are arranged obliquely 
and transversely toward the base, and mostly transversely in the middle por- 
tion ; summit of the calicles strongly eight-lobed, the lobes filled with smaller, 
stout, blunt spicula. Height of one of the largest examples, 170 mm.; breadth, 
110 mm. 
Station 227, in 573 fathoms, off St. Vincent, W. I., Blake Expedition, 
1878-79. Several specimens. Also from several other localities in the same 
region, and off Cuba. 
This species is dedicated to Mr. J. W. Fewkes, of the Museum of Compara- 
tive Zodlogy. 
Iridogorgia VeErRRILt, gen. nov. 
Axis partially calcareous, with a brilliant iridescence; in the only known 
species it grows in the form of an upright spiral, or helix, from which a single 
series of long, slender, simple branches is given off on the outer side, so that 
they likewise have a spiral arrangement. 
Calicles scattered along the branchlets, far apart, verruciform, with a swollen 
base, elongated in the direction of the branch, filled with slender fusiform 
spicula. Tentacles large, not retracted in the alcoholic examples, and not stif- 
fened by spicula. Ccenenchyma very thin on the branchlets, containing slender 
fusiform spicula; on the stem and basal portion of the branches covered with
