and tlie Zoaniliaria, especially in reference to the peculiar combination of the 
structural elements or spheromeres. Proc. Post. Soc. Nat. Hist. vol. x. Oct. 
1805, p. 22. 
Verrill, in a critical notice of Kolliker’s ‘ leones Ilistiologicoe,’ pt. 2, 
states that his new genus Lissoyorgia will yield the priority to Echinoyorgia 
(Kolliker). [Verrill’s genus was not published until October 1805. Kolliker’s 
‘ leones,’ though dated on the titlepage as 1805, was, as indicated on the 
cover, not published until 1800.] Verrill believes Kolliker to be certainly at 
fault in uniting Gorgonia suherosa (Ellis), Alcyonmm plexaureum (Lanix.) 
and A. ashestinum (Pallas) into one species, Briaremn stiherosum (Dana) j for, 
as ho has previously shown (Bull. Mus. Comp. Anat. no. 3, p. 39), they repre- 
sent three very distinct species and two genera. Verrill, Am. Journ. Sci. 
2nd series, vol. xlii. Sept. 1800, p. 283. 
Verrill (Proc. Post. .Soc. N. H. x.) describes the following known species 
of his suborder Gorgonacea : — Plexaura friahilis (Lanix.), Acantliogorgia coc- 
cinea (Verr.), pi. 0. fig. 7, and Parisis Icixa (Verr.). 
New genera : — 
Calgptrophora, Gray, 1. c. p. 25. Coral cylindrical, furcately branched ; 
the branches elongate, subsimple ; the axis horny j the bark thin, smooth, 
calcareous, with regular equidistant whorls of cells j cells with a circular 
mouth having a raised edge, placed close together and forming a raised ring 
round the coral. Each cell is furnished with two obconic pellucid cells 
placed one on the other ; the lower cell is pellucid, apparently articulated to 
the axis of the coral, very narrow near the mouth of the cell and wide at the 
other end j the lower surface of the outer aperture is furnished with two 
elongated liorn-like processes. To the centre of this ba.sal cone i.s articulated 
or allixed a similar pellucid horn-coloured cone or, rather, conical vase, which 
is furnished with a slightly keeled edge at its widest part, and then contracts 
as if it had a .shorter conical lid, with an aperture in the middle of this lid- 
like contracted part for the emission of the polype. The two cones are as it 
were articulated to the stem ; and the lower one stands at right angles with 
regard to it, and the upper at right angles with regard to the lower one, so 
that the aperture of the upper one is vertical. Sp. C. jcqwnica^ sp. n.. Gray, 
1. c. p. 20. fig. 1, .Japan. 
Ilomophytonj Gray, /. c. p. 27. Coral arborescent, rather flabellato, fur- 
cately branched ; branches subcylindrical, elongate ; axis wood-like, soft, 
formed of numerous spicula intermixed with a cellular substance ; bark 
thin, with a smooth external surface ) the cells of the polypes forming 
live longitudinal series of compressed tubercles, those of the neighbouring 
series alternating on the ends of the younger branches, becoming further 
apart, more irregularly distributed, and scarcely elevated in the older part 
of the branches. This genus is nearly allied to Paragorgia (Milne-Edwaids), 
but dilFers from it in the axis being of a uniform cork-like texture, without any 
tube or spongy cavities. Sp. II. gattyia;, sp. n.. Gray, 1. c. p. 27. fig. 2, Capo 
of Good Hope. 
Parisis, g. n., Verrill, List &c. p. 37. Corallum iiTegularly branching^ 
nearly on a plane. The axis consists alternately of calcareous and suberous 
segments, of uniform thickness, traversed by numerous narrow sulcations. 
The branches originate from the calcareous segments. Coenenchyma persis-
