Afterflossenstacheln 0; Afterflossenweichstrahlen: 0. Uniform grey-brown coloration; short, blunt snout; high sail-like dorsal fins with spines and broad apices, first dorsal spine inclined backward; high, thick triangular body with large, rough denticles; circular spiracles; lanceolate upper teeth, lower blade-like teeth in less than 12 rows (Ref. 247).
Found on outer continental and insular shelves and uppermost slopes (Ref. 247). Probably feeds on bottom invertebrates and fishes. Ovoviviparous (Ref. 205). Taken incidentally with bottom trawls but probably not used (Ref. 247).
