Dr. GRAY (Ann. N. H. (4) v. pp. 405-408) has established the following
new genera from specimens in the British Museum :—
Busella, gen. nov., Gray (ibid. p. 405). B. occatoria=Rhipidogorgia oceatoria,
M.-Edw. & Haime, Guadeloupe.
Muritella, gen. nov., Gray (ib. p. 405). M. fucosa= Gorgoniafucosa, Valen.
(= Gorgonia palma va,r. alba, Esper, and G. albicans, Koll).
Boarellafiabellata, gen. et sp. nov., Gray (I. c. p. 406). Coral branched in
a plane, fan-shaped, forming an oblong frond with a single stem; branches
and branchlets slender, nearly of the same diameter, netted; branches diverging
and often inosculating, some of the marginal branchlets free. Bark
thin, formed of thin scales or spicules. Polyp-cells subcylindrical, elongate,
truncate, membranaceous, translucent, with a circular mouth with 10 marginal
folds and 10 short valves in an irregular series on each side of the
branches, diverging in different directions, one, sometimes two or three
together. Axis continuous, horny. British Museum. Locality unknown.
MenaceUa, gen. nov., Gray(Z. e. p. 406). M. reticularis•= Gorgonia reticularis,
Pallas.
Phaoeella, gen. nov., Gray (/. c. p. 406). P. tuberculata= Gorgonia tubercu-
lata, Esper.
Bovella ramulosa, gen. et sp. nov., Gray (/. e. p. 407). Coral branched,
fan-shaped, expanded into an oblong frond; stem simple; branches and
branchlets slender, of the same diameter throughout, branches radiating and
irregularly furcately divided, with abundance of short branchlets arranged
rather pinnately and diverging at nearly right angles, forming a more or less
regular network; many of the branchlets, especially the marginal ones, free.
Bark furfuraceous, formed of very small soft spicules or thin scales. Polypcells
circidar, prominent, with a sunken centre and a furfuraceous surface,
