4, Corynitis, M‘Crady. 
Trophosome.—Polypites springing from an adherent base* ; 
tentacles capitate, scattered over the body of the polypitey. 
Gonosome. — Gonophores phanerocodonic, borne upon the 
body of the polypite. Umbrella deep bell-shaped, thick-walled, 
with clusters of thread-cells imbedded in its walls, and with the 
roof of its cavity rising in four overarched spaces between the 
——- 
_radiating canals; manubrium massive; radiating canals four; - 
marginal tentacles four, club-shaped, with basal bulbs, each 
furnished with an ocellus. 
Corynitis Agassizi, M‘Crady f. 
5. CanpELABRUM, De Blainville. 
Trophosome.—Polypites clavate, springing from a tubular 
adherent hydrorhiza, which is invested by a periderm ; tentacles 
wart-like, scattered over the body of the polypite. 
Gonosome.—Gonophores adelocodonic (?), on gonoblastidia 
which are clustered round the base of the polypite. 
Candelabrum is De Blainyille’s name for the Lucernaria Phrygia 
of Fabricius, which Agassiz has shown to be identical with the 
Myriothela of Sars, and to which he has accordingly restored the 
original name given by De Blainville. 
Candelabrum Phrygia, Fabricius (sp.), = Lucernaria Phrygia, — 
Fabricius. 
Candelabrum arcticum, Sars (sp.),= Myriothela arctica, Sars, 
Pennaride. 
1. Vorticuava, Alder. 
Trophosome.—Polypites solitary, borne on the summit of a 
simple hydrocaulus, which is attached by a simple conical (?) © 
hydrorhiza; periderm a delicate transparent film investing the — 
hydrocaulus and the hydrorhiza ; tentacles in two verticils, those 
composing the proximal verticil long and filiform, those com- 
posing the distal verticil short and capitate. 
Gonosome unknown. 
Vorticlava humilis, Alder. 
Vorticlava Proteus, Wright. 
* The nature of this base has not been described: it is probably a 
tubular reticulated hydrorhiza invested by a periderm. 
+ The trophosome of this genus has been described and figured by 
Agassiz under the name of Halocharis (Cont. Nat. Hist, U. 8. vol. iy. 
P 239), but has been since (op. cit. p. 340) referred by him to the genus 
orynitis. 
{ The Halocharis (Corynitis) spiralis of Agassiz, op. cit, p. 239, may con- 
stitute a second species of Corynitis; but there is no mention of its gono- 
some, and it is not clear whether Agassiz does or does not regard it as di- 
stinct from Corynitis Agassizt.
