Distribution: Chun's (1888) specimens of Sphaeronectes brevitruncata came from Oratava (Tenerife) in the Canary Islands, presumably from superficial waters; Stepanjants's (1967) specimens of Monophyes japonica came from the Japan Sea (39°21'N, 134°36'E) in hauls made over 0–100 and 100–200 m depth ranges; and C. Carré's (1968c) specimen of S. irregularis var. presumably was collected off Villefranche-sur-Mer (western Mediterranean). It is here assumed that Chun's Diplophysa codonella is actually the eudoxid stage of S. koellikeri .
