ANTHOMEDUS.E. 7 



CLADONEMA, Dujardin, 1843. 



Four or five bifurcated or eight to ten simple radial-canals. Branched marginal tentacles. 

 Simple oral tentacles. No brood-sac above the stomach. Hydroid: Statin Jin 

 Dujardin. 



DENDRONEMA, Haeckel, 1879. 



Similar to ClaJonema, but with branched oral tentacles and with brood-sac above stomach. 



Family No. 3, OCEANID.S, sensu Vanhoffen. 



Anthomedusae in which the gonads are segregated and developed upon the interradial 

 or adradial sides of the manubrium. With unbranched marginal tentacles. Mouth with 

 four lips. 



Subfamily No. i, TIARIN.E. 



Unbranched radial-canals. Marginal tentacles separate; not grouped into clusters. No 

 oral tentacles. Tentacles hollow. When present the ectodermal ocelli are upon the abaxial 

 sides of the tentacle-bulbs. With the exception of Calycopsis all of the genera have four 

 radial-canals. 



PROTIARA, Haeckel, i%jq = Halitiara, Fewkes, 1882. 



Four radially placed, well-developed tentacles. Four interradial gonads with smooth 

 outer surfaces. With or without marginal cirri. External surfaces of gonads smooth. 

 Four cruciform, simple lips. No ocelli on the velar sides of the tentacles. 



HETEROTIARA, Maas, 1905. 



Eight or more tentacles. The ring-canal gives rise to blindly-ending centripetal vessels. 



STOMOTOCA, L. Agassiz, \%()2 = Amf>hinema-\-Stomotoca + Codonorchis, Haeckel, 1879. 



Two well-developed and many rudimentary tentacles. External surfaces of the adradial 

 gonads are thrown into transverse folds. Hydroid: Pengonimus. 



DISSONEMA, Haeckel, 1879. 



Similar to Stomotoca, but the gonads finally migrate outward along the four radial-canals. 



PANDEA, Lesson, 1843. 



Four or more tentacles. Gonads four interradial, folded ridges on the sides of the 

 stomach but these gonads are not completely separated in the four principal radii. 

 Hydroid: Dcndroclava ( ? ?). 



TURRIS, Lesson, 184.3 = Tiara + Turris + Catablema, Haeckel, 1879. 



Four or more tentacles. Four interradial horseshoe-shaped gonads on the stomach 

 wall. These are composed of more or less fused ridges or network-like swelling. 

 They are completely separated in the four principal radii. Hydroid: Clirculu Wright. 



CONIS, Brandt, 1834; Haeckel, 1879. 



Similar to Pandea, but the tentacle-bulbs give rise to abaxially-placed clubs which bear 

 ocelli. 



CALYCOPSIS, Fewkes, 1882. 



Sixteen simple, separate radial-canals. Eight transversely folded, adradial gonads. 

 Ring-canal simple. 



Subfamily No. 2, MARGELINjE. 



With four unbranched radial-canals. With oral tentacles, or nematocyst-knobs, upon 

 the lips. Tentacles solid. When present the ectodermal ocelli are upon the inner (velar) 

 sides of the tentacles. 



CYTVEIS, Eschscholtz, iS2() = Cytxis + Cubogastcr, Haeckel, 1879. 



Four simple marginal tentacles. With simple, unbranched, oral tentacles. 



PODOCORYNE, Sars, \?>J t b = Dysmorf>hosa-\-Cytteandra, Haeckel, 1879. 



Eight or more simple marginal tentacles. With simple, unbranched, oral tentacles. 

 Hydroid: Podocoryne. When present the peduncle above the stomach is solid and 

 gelatinous.
