26 BULLETIN OF THE 



Taken at numerous localities in the Caribbean Sea and among the Antilles, 

 in 88 to 163 fathoms, by the Blake, in 1878-79, and ott' Cuba, in 288 fath- 

 oms, in 1880. 



Chrysogorgia Fewkesii Verrill, sp. nov. 



Chrysogorgia Desbonni Pourtales, 18G8 {noii Duch. & Mich.). 



Coral tall, spirally branched, nearly as in Basygorgia 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 hrst division being usually about 10 to 12 mm. from the main stem; 

 subsequent divisions are at une(|ual distances, the final branclilets numercms, 

 A^ery small, and spreading widely. A.xis 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. Cocnen- 

 chyma tliiii, 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 nuddle, with the sum- 

 mit and base enluiged; 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 obli(|uely 

 and transversely toward the base, and mostly transversely in the middle por- 

 tion ; summit of the calicles strongly eight-lobed, the lobes tilled with smaller, 

 stout, blunt spicula. Height of one of the largest examples, 170 mm.; breadth, 

 110 mm. 



Stati<jn 227, in 573 fathoms, off St. Vincent, W. L, 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 Zoology. 



Iridogorgia Verrill, 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 oft" 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 fu.siform 

 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
