Two specimens, which I identify as this subspecies, have been kindly lent by Mr. Glauert, who collected one of them at Cottesloe ( Mus. regd. no. ), a beachworn specimen, with fins eaten away, which had probably floated down from the tropics. The other example (no. ) was from Hanover Bay in the Kimberleys, presented by Mr. Deutschmann. The latter specimen is larger and more complete and is described below with notes on the differences between the two when such occur. D., 26;

The latter specimen is larger and more complete and is described below with notes on the differences between the two when such occur. D., 26; A., 4; P., left 16, right 17. Caudal rudimentary in (double with 12 rays and little more than eye in length in ). Rings 23 + 46 (or 20 + 39 in ). Subdorsal 3 + 2. Head (30 mm.) 12-9, depth at dorsal origin (8) 48-5 in total length (c. 388). Snout, 16 mm.; eye, 4; postorbital, 10; interorbital, nearly 4. Head longer than dorsal base. Axis of head at an obtuse angle to that of body. Surface of head and body with fine rugae which form vertical striae on parts of lateral scutes. Snout as broad as deep. Forehead ascending from snout at an obtuse angle. Orbits apparently not prominent. Interorbital flat across sunken area between orbital bevels. No rostral crest, merely a short, slight ridge anteriorly. Head about 13 to 19 in total length, about 2J to 3i in trunk. Operculum without keel but with radiating pits and pimples sometimes forming streaks or reticulations and rough-surfaced. A prenuchal and two nuchal shields, without ridges. Gill-openings crescentic, close together, near back. Form very elongate. Trunk swollen in middle in , but not in Body six-angled, without ventral carina, slightly deeper than broad, not dilated. Tail four-angled, wider than deep, at least anteriorly. Interstitial scutella well developed. Body- ridges weak, without spines. Superior ridges of trunk converging towards end of dorsal base, discontinuous with superior ridges of
