N. brychia. Holotype in the B.M.N.H. No. 1887.2.9.671.; 16.6 X 9.2 X 8.3 mm. Dirty white in colour, some nodules appearing darker, sculptured with 17 axial ribs and 3 broad grooves on the penultimate and 20 ribs and 10 cords on the body whorl, columella smooth apart from a single basal fold, outer lip with 9 plicae. Off Gomera, Canary Is, 28° 03'15"N and 17° 27'W, 620 fathoms (1135 m).
The species has not been mentioned in East Atlantic faunal lists and does not appear to have been recognised since its description. It is superficially similar to N. reticulatus (Linnaeus), but the columellar callus in N. brychia is not spreading above the parietal wall but is small and well-defined.
