Campanularia macroscypha Allman, 1877: 11 , pl. 8, figs. 1, 2.— Fraser, 1943: 88.

Type locality. USA: Florida, off Sand Key , 120 fathoms (219 m) ( Allman 1877) .

Voucher material. Off St. Lucie Inlet, 27°10.8’N, 80°02.5’W, on Eudendrium carneum , 22 m, 24.vii.1975, Johnson-Sea-Link, JSL 273, one colony, up to 2 mm high, without gonophores, coll. T. Askew, ROMIZ B1088 .— Off St. Lucie Inlet, 27°11.4’N, 80°00.9’W, 42 m, 18.v.1976, Johnson-Sea-Link, diver lockout, one colony, up to 4 mm high, without gonophores, coll. M. Flake, ROMIZ B1101 .— Off St. Lucie Inlet, 27°10.8’N, 80°00.8’W, 43 m, 24.viii.1977, Johnson-Sea-Link, JSL 1439, diver lockout, one colony, up to 1.1 cm high, without medusa buds, coll. J. Reed, ROMIZ B1104 .

Remarks. Campanularia macroscypha Allman 1877 is distinguished by having long, cylindrical hydrothecae with a dozen or more deeply-cut, linguiform cusps, and irregularly-segmented pedicels. It is known only from the southeastern United States and Gulf of Mexico. A hydroid of relatively deep waters, its previously-known bathymetric range is 84–1119 m ( Henry et al. 2008). Voucher material above from St. Lucie Inlet was from shallower depths of 22– 43 m. Specimens reported from a station (Stn. 117, 32°04.03’N, 65°02.48’W) on Challenger Bank, off Bermuda ( Calder 2000) were collected at 49 m.

Gonothecae of this species remain undescribed.

Reported distribution. Atlantic coast of Florida. First record.

Western Atlantic. Cape Lookout, North Carolina ( Henry et al. 2008) to the Gulf of Mexico north of Yucatan ( Fraser 1944), as well as Bermuda ( Calder 1998, 2000).
