|---|
| al. 2013: 749) |
|---|
| Corymorpha microrhiza | Species redescribed by Svoboda & Stepanjants (2001). Gonophores as fixed |
|---|
| (Hickson & Gravely, 1907)—P + G | sporosacs, of cryptomedusoid type. Antarctica (Svoboda & Stepanjants 2001: 64) |
|---|
| Corymorpha multiknoba | Umbrella with rounded top and no apical projection; mesoglea thick; mouth |
|---|
| (Xu, Huang & Guo, 2014)—M | circular; main tentacle borne on broad, cushion-shaped bulb, very long, with over |
|---|
| 100 abaxial knobs of nematocysts, in addition to the terminal one, of similar size; 3 |
|---|
| perradial, cone-shaped, non-tentacular bulbs, all alike, extending a short distance up |
|---|
| the exumbrella. Northern part of South China Sea (Xu et al. 2014: 909) |
|---|
| Corymorpha nana | Insufficiently known nominal species, recalling C. nutans, but of smaller |
|---|
| Alder, 1857—P + M | proportions; taxonomic status uncertain; a recent diagnosis is given by Schuchert |
|---|
| (2010: 389); newly-released medusa with likely moniliform main tentacle. United |
|---|
| Kingdom, Norway (Schuchert 2010: 390) |
|---|
| Corymorpha nanhaiesis | Manubrium broad, with “vacuolated endodermal cells in the upper part, gonads in |
|---|
| (Huang, Xu & Lin, 2012)—M | the lower part”; 4 very much elongated bulbs extending up the exumbrella; main |
|---|
| tentacle “terminating in two cnidocyst knobs”, intermediate know encircling the |
|---|
| tentacle (tentacle moniliform). South China Sea (Huang et al. 2012: 520) |
|---|
| Corymorpha normani | Umbrella with conspicuous conical, apical projection; exumbrella with 12 |
|---|
| (Browne, 1916)—M | “longitudinal streaks of nematocysts extending from the margin to the apex, |
|---|
| having lateral branches and forming a kind of network on the lower part of |
|---|
| the umbrella”; a conical apical chamber; “four very thick radial canals and a |
|---|
| very thick circular canal”; manubrium extending beyond velum; main tentacle |
|---|
| “with a long, sac-shaped basal bulb, and terminating with a large globular ball |
|---|
| containing nematocysts, and also three other globular clusters of nematocysts |
|---|
| probably unilaterally arranged”; clusters “projecting from the tentacle”; “their |
|---|
| exact position on the tentacle is doubtful”; “Three small perradial bulbs without |
|---|
| tentacles”. North of Chagos, Indian Ocean (Browne 1916: 174–175) |
|---|
| Corymorpha nutans | Polyp redescribed by Schuchert (2010: 382–383). Medusa with “pointed conical |
|---|
| M. Sars, 1835—P + M | apical process containing thin, long apical canal in its centre (sic)”; a “short gastric |
|---|
| gelatinous peduncle”; main tentacle moniliform “with 40–80 annular nematocyst |
|---|
| clusters and one terminal cluster of same size”; 3 additional, comparatively |
|---|
| smaller bulbs either devoid of tentacles or, rarely, “with short, knobbed tentacle |
|---|
| rudiments” (Schuchert 2010: 384). Polyp found in NW Europe, the Mediterranean |
|---|
| and around Iceland; medusa occurs in NW Atlantic from Morocco to Iceland and |
|---|
| Norway, including the North Sea, as well as in the Mediterranean and the Black Sea |
|---|
| (Schuchert 2010: 386). |
|---|
| Corymorpha palma | Polyp described in the original account. Gonophores as medusoids, “ permanently |
|---|
| Torrey, 1902—P + G | fixed […] each with a ring canal, four radial canals, and a manubrium at least twice |
|---|
| as long as the bell, without a mouth; tentacles wanting; velum may be present |
|---|
| or absent” (Torrey 1902: 37); “subumbrella muscle still remain, therefore, and |
|---|
| function actively—an interesting persistence of a habit which the species appears to |
|---|
| have outgrown” (Torrey 1907: 255). California, USA (Fraser 1937: 49) |
|---|
| Corymorpha parvula | Species redescribed by Svoboda & Stepanjants (2001). Gonophores as fixed |
|---|
| (Hickson & Gravely, 1907)—P + G | sporosacs of cryptomedusoid type. Antarctica (Svoboda & Stepanjants 2001: 66) |
|---|
| Corymorpha pendula | Polyp described in the original account. Gonophores probably eumedusoids; they |
|---|
| L. Agassiz, 1862—P + G | “do not become free individuals, but remain attached, develop their generative |
|---|
| material and then wither and die” (L. Agassiz 1862: 281); histology studied by |
|---|
| May (1903: 591–597). Atlantic coast of USA (Fraser 1944: 89) |
