Pennatulida. 
Distichoptilum, g. n. Slender Pennatulids, with an axis through the 
whole length, and polyps arranged alternately, in a simple row on each 
side ; calicles bilobed, appressed ; zooids three to each polype, one in 
front, and one on each side of each cell ; spicula abundant in the calicles, 
rhachis, and stalk. D. gracile , p. 362. Verrill, (36).

Radicipes , g. n., Stearns, (30) p. 97. Its angularity of style and one- 
side arrangement of polyps point to Pavonaria, and its root-shaped base 
closely connects the Pennatulids with Gorgonacece. R. pleuro-cristatus y

Martinique and Barbadoes. 
Lepidisis , g. n. Axis with long tubular calcareous joints alternating 
with short horny ones, simple or branched ; base divided into long irre- 
gular flat lobes ; coenenchym thin, with an external layer of scale-like 
spicula. Allied to Acanella. L. caryophyllia , p. 18, Guadaloupe, &c., 
L. longijlora , p. 19, Grenada, &c., L. vitrea, p. 20, St. Lucien. 
Chrysogorgi[i]dce , fam. nov. The known species are all inhabitants of 
deep waters, and of W. Indian seas, except Dasygorgia agassizi, New 
England. The coral is variously branched, the branches most commonly 
taking a spiral arrangement. The axis is partially calcareous, generally 
with a brilliant iridescence and metallic lustre. The calicles are promi- 
nent and scattered along the branches, and covered with moderately long 
flat spicules. 
The 3 genera are arranged as follows : — 
A. Much branched, often spirally ; the branches ) Chrysogorgia. 
forking J Dasygorgia. 
B. Axis forming a spiral or helix, with slender ) i r \d 0 g 0r g{ a 
undivided branches in a single spiral row . /
