Egmundella grandis Fraser, 1941b 

Egmundella grandis Fraser, 1941b: 82  , pl. 16, figs. 8a, b.

Syntypes. USNM 43455View Materials: USA, Virginia, Chesapeake Bay , off mouth, R/ V Fish Hawk Sta. 897, 37°25’N, 74°18’W, 16 November 1880, 288 m, trawl, several small colonies or colony fragments, labelled “ type ”; ethanol + four slides.GoogleMaps 

Lectotype, by present designation. USNM 43455View Materials: USA, Virginia, Chesapeake Bay , off mouth, R/ V Fish Hawk Sta. 897, 37°25’N, 74°18’W, 16 November 1880, 288 m, trawl, one sparse colony or colony fragment on a bivalve shell, in mediocre condition, without gonophores, labelled “ type ”; ethanol.GoogleMaps 

Paralectotypes. USNM 1458863View Materials: USA, Virginia, Chesapeake Bay , off mouth, R/ V Fish Hawk Sta. 897, 37°25’N, 74°18’W, 16 November 1880, 288 m, trawl, several tiny colony fragments, in mediocre condition, without gonophores; ethanol + four slides.GoogleMaps 

Type locality. USA, Virginia: slope waters east of Chesapeake Bay, 37°25’N, 74°18’W (north of Washington Canyon), 157.5 fm (288 m) ( Fraser 1941b).

Current status. Valid.

Remarks. Material designated as the “ type ” of Egmundella grandis  by Fraser (1941b) is at the NMNHAbout NMNH ( USNMAbout USNM 43455). That collection comprised syntypes, with material in ethanol and on four slides. The best of these specimens, growing on a bivalve shell and returned to the original vial ( USNMAbout USNM 43455), is designated here as the lectotype. All others in the type series are paralectotypes ( USNMAbout USNM 1458863). The four slides forming part of this series are relatively recent preparations and were not made by Fraser.

While the location of this collection was given by Fraser (1941b) as the state of Maryland, coordinates reveal instead that the specimens were from the continental slope off the eastern shore of Virginia.

On the basis of morphology, biogeography, and habitat, a report of E. grandis  from shallow waters of Belize ( Spracklin 1982), in the Caribbean Sea, is considered by us to be a misidentification. No other records exist of this obscure and briefly described species, known only from its trophosome. Regarded as valid here, it is not listed in WoRMS. The species was excluded from the lists of Cairns et al. (1991, 2002) earlier because its depth (288 m) was below the 200 m bathymetric limit set in those two works.
