Diagnosis

A relatively gracile subspecies of E. parrae with up to 46 (mode 30) usually serrated arms up to 125 mm long (mean 99 mm); number of IIIBr 2–5 (mode 3); stalk length up to 50.5 cm (mean 23.5 cm); proximalmost stalk diameter up to 5 mm (mean 4.1 mm); proximal cirri remaining rudimentary before the 6th nodal; internodal thickness and width regular; number of internodals per noditaxis up to 16 (mean 12); nodals with ratio of height to diameter 0.51–0.52; cryptosymplexies with a slight inner symmorphy of interpetaloid zones; number of cirrals per cirrus up to 38 (mode 30), fewer than in the two other subspecies.

Type locality

Off northern coast of Santa Clara Province, Cuba, at a depth of 482 m. Holotype: Catalogue no. MCZ 1000, Museum of Comparative Zoology, Harvard College, Cambridge, Massachusetts; first figured by H.L. Clark 1941, pl. 1.

Occurrence

From the northwestern Bahamas to the eastern end of Hispaniola, off northern and southern Cuba, at depths from 402 m to 832 m (David 1998); greater abundance in the northwestern Bahamas (Oji 1990) probably related to the relatively high number of dredges and submersible dives in this area.
