placed on all sides of the branchlets and on the internal surface of the 
branches. Axis continuous, horny, black. British Museum. Locality not 
given. 
Menella indica^ gen. et sp. nov., Gray (/. c. p. 407). Coral cylindrical, end 
(of the branches ?) clavate, rounded, surface spiculose. Polype-cells on all 
sides of the cylindrical stem (and branches), close together, forming a rough 
spiculose surface with hexagonal areola). Polypes retractile j when retracted, 
convex, with an oblong concavity, surrounded with spicules. Axis horn)'^, 
black. Hah. Bombay. 
Lignella, gen. nov.. Gray (l.c. p. 407). L. 7'ichardi=.Gorg(mia richardi, 
Lamx. 
Leucoella eervicornis, gen. et sp. nov., Gray (/. o. p. 407). Coral branched, 
fan-like, in the same plane, compressed ; branches furcate, upper side convex 
or angular, lower side concave, smooth, barren, with a more or less wide cen- 
tral groove. Bark thin and smooth. Polype-cells large and spherical, scat- 
tered or in lines on the upper surface and margin of the stem and branches. 
Axis white, wood-like, soft, with fusiform warty spicules, which are generally 
slender and elongate, but some are thicker and more ventricose. Brit. Mus. 
Loc. unknown. 
Mhipidella verticillata, Solander. This, the Gorgonia verticillata, Esper, 
Rhipidogorgia verticillataj M.-Edw. & Ilaime, and Suberigorgia verticillata^ 
ICdll., should be restored as a distinct generic type (Gray, loc. cit. p. 407). 
Vioa asbestinaf Nardo. In like manner, Dr. Gray {loc. cit. p. 408) re-esta- 
blishes Nardo’s generic term for this coral ( = Lobidaria asbestina, Ehr., Rri- 
nreurn asbestiniim, Verrill, and B. suberosmn (pars), KolL). 
From conclusions arrived at after careful examination of the calcareous 
spicula in the sections Primnoacece, Gorgoniacece^ and Gorgoriiellacece of the 
subfamily Gorgoniimo and family Gorgoniidce, Mr. W. S. Kent (M. Micr. J. 
Feb. 1870, pp. 76-94), proposes the following alterations in the nomenclature 
of certain species : — To Muricea should be referred Gorgonia jdantaginea, Lmk. 
(JEunicca plantaginea, M.-Edw.) } to Echinogorgia, Koll., Rhipidogorgia co- 
arctata, M.-Edw., Muricea f ungif era, M.-Edw., and Gorgonia granifera, Lmk. j 
to Eunicea, Plexaura pensilis, Val., and P.pendulayVdA .. ; to Plexaurella, Gor- 
gonia hetero}iora,\jm)s..', to Gorgonia, Mtiricea placomus,y el. (non 
Esp.), Plexaura raeemosa, Val., Verrucella furcata, M.-Edw. ; to Leptogorgia, 
Gorgonia miniata, pumicea, and ramulus, M.-Edw. Spicules of the Lepto- 
gorgian type occur in various modifications in each of the following genera 
of Milne-Edwards : — Lophogorgia, Pterogorgia, Xiphigorgia, Rhipidogorgia, 
Phyllogorgia, Ilymenogorgia, Phycogorgia, and Gorgonella. Verrucella violacea 
should probably be made the type of a new genus, having incorporated with 
it Gorgonia lilacina and sanguinolenta, Val. To Juncella should be referred 
Ctenocella pectinata, Primnoa myura, Leptogorgia bnryana, Rhipidogorgia 
lac^iens, plagalis, umbraculum, Pterogorgia betulina, Verrucella Jlexuosa.
