Comment:
Sampled by M. Pruvot and originally identified by E. Topsent as 'Cliona labyrinthica', tentatively identified as S. coralliphagum by C. Schönberg. All measurements are of mature, fully formed oxeas to allow statistical comparison with other samples. Measurements conducted by C. Schönberg on preparation of acid-cleaned spicules made by E. Topsent. Data are sorted vertically by spicule width.; Topsent, Emile (1900) Étude monographique des spongiaires de France. 3. Monaxonida (Hadromerina).
