rings, forming regular whorls round the branches, the cells oblong cylin- 
drical, contracted at the base, and each covered with 6 longitudinal series of 
transverse oblong hexagonal scales, truncate at top, and closed with elon- 
gated, more or less acute scales, converging to a point when the animal is 
withdrawn j axis covered with small scales.” F. rossi^ sp. n., pi. 62.

Jukella, g. n.. Gray. “ Coral hard, fleshy, forming a thick, smooth, barren 
stem, marked by irregular longitudinal grooves or ridges, divided at the top 
into irregular transverse foliaceous expansions, sinuated or lobed on the 
margins, which are covered with close, retractile polypes on each of their 
sides. All parts of the coral studded with calcareous cylindrical spicules, 
which have 4 more or less prominent, separate, transverse plates, which 
are largest in the middle, and more or less small or rudimentary at the 
ends.” J. cristata, sp. n., Hardy’s Island, South Pacific. Ann. N. H. (4) ix,

Sydella, g. n.. Gray (5, p. 747, pi. 63. figs. 8 & 9). Described from a draw- 
ing by Dr. Hooker, representing the apex of a branch [!]. “ Coral erect (?), 
straight, cylindrical, rather tapering, covered with cylindrical cells, tapering 
at the end and placed in 4 rather irregular series, covered externally with 
red fusiform spicules placed very close together in a longitudinal direction. 
Polypes completely retractile, leaving a small rounded end to the cell when 
retracted.” JS. australis, Gr., Sydney.

Australia as the backbone of a marine animal caught swimming with great 
rapidity in shallow water,” and described by Gray in Cat. Sea-pens, B. M., 
under the name of O. cliftoni (length 11”), though he considered it very 
doubtful as one of the Pennatulidce, and even suggested that it might be the 
long conical bone of an unknown cuttlefish.” The microscopical examina- 
tion by Carter and Kolliker of a similar very long (64^ inches) slender bone 
(O. septentrionalis),T^mhdi\Ay from the west coast of North America (Van- 
couver’s Island), leaves no doubt that it is the axial style of an unknown 
Jlaliptet'is or allied genus, though some still think it to be the backbone of 
a fish [!].
