Type locality. USA: Florida, off Alligator Reef , 24°41’45”N, 80°27’45”W, 118 fathoms (216 m) ( Fraser 1943: 76) GoogleMaps .

Voucher material. Off Vero Beach , 27°41.2’N, 80°14.5’W, 17 m, 13.ii.1974, small biological dredge, R/ V Gosnold Station 220/226, one erect and fascicled colony, in poor condition, 1.9 cm high, without gonophores, ROMIZ B1075 GoogleMaps .— Off St. Lucie Inlet, 27°10.8’N, 80°00.8’W, 44 m, 19.iv.1977, Johnson-Sea-Link, JSL 2187, diver lockout, one colony, up to 1.1 cm high, with medusa buds, coll. L. Edmiston, ROMIZ B1106 GoogleMaps .

Remarks. Earlier, I regarded Turritopsis fascicularis Fraser, 1943 as conspecific with T. dohrnii ( Weismann, 1883) from Europe ( Calder 1988: 10). In the absence of information on life histories and relationships between European and American populations, however, they are maintained here as distinct species. Unlike T. nutricula McCrady, 1857 , colonies of both nominal species are erect, polysiphonic, and branched.

Colonies identified as Turritopsis fascicularis from deep waters off Bermuda ( Calder 1998: 10) have fixed gonophores rather than free medusae, as originally described in this species by Fraser (1943), and may represent an undescribed species.

Fraser’s (1943) type material of Turritopsis fascicularis from the Florida Keys was collected within the Gulf of Mexico, as defined above .

Reported distribution. Atlantic coast of Florida. First record.

Western Atlantic. South Atlantic Bight ( Wendt et al. 1989) to the Caribbean Sea ( Calder 1991b).
