Hydraspis victoriae

Hydraspis victoriae, Gray, Shell ovate, convex, blackish brown marbled with grey and rather rugose above, beneath convex, yellow olive, with slight, impressed, narrow, netted grooves: vertebral plates nearly square, as long as broad, the fourth 6-sided, elongate; the marginal plates rather narrow in front, broader and slightly bent upon the sides, dilated, rather produced, and leaving 2 or 3 notches the tail behind; the sternum narrow; rather convex, shelving on the sides, and with a broad rounded notch behind. The back is regularly convex: the front cavity is much contracted by two rather diverging septa, only leaving a space almost half the width of the outer opening; the sternum is only about one third the width of the lower surface in the middle, and rather tapering behind: the vertebral column is sharply keeled within, and the bones of the pelvis are very strong: the first and second marginal plates are rather broad, the third narrow, the fourth and rest broader; the middle of the fourth and eleventh is opposite the suture between the costal plate. Inhabits Victoria river, North-west coast of New Holland; Captain William Campbell, R,N.
