Ischnochiton gabrieU Hull, Proc. Roy.' Soc. Vic, xxv., 1912, 120, PL viii., f. 1 a-f. Type in coll. Gabriel. Shell small, elongately oval, elevated, subearinated, side slopes steep and straight. Colour uniformly pallid, of various shades of cream and pink mottled and streaked with yellowish brown. The whole shell is granosely quincuneially sculptured, but no radiation of grains is at all discernible. Senile shells show concentric growth lines on all valves. The lateral areas of the median valves are well elevated and notably narrowed; and the grains are a little more regular towards the edges. Posterior valve with mucro slightly post-median. Girdle fairly wide; scales very small. Interior white. Slits 10-0-0. Sutural laminae large, broad, distant. Dimensions: 6 x 4 mm. Station: Dredged in five to twenty fathoms. Habitat: Victoria; New South Wales. Remarks: This species is apparently common in Sydney Harbour, having been dredged in numbers near the Sow and Pigs Reef by Brazier fifty to sixty years ago, and by Hull in 1911. The type was dredged in Western Port, Vic- toria, by C. J. Gabriel. SUBTERENOCHITON BEDNALLI. (Text-fig. a). Ischnochiton bednalli Torr, Trans. Roy. Soc. S. Aust., xxxvi., 1913, 166, PL v., f. 3 a-f. St. Francis I., Nuyts Archi- pelago, South Australia. Type in coll. Torr. Shell small, elliptical, valves wide, rounded, slightly carinated, side slopes curved. The posterior margins of the valves project considerably and give a verandah-like ap- pearance. The valves are exceedingly delicate. Colour uni- form cream. Anterior valve having about twenty microscopically pustulose lirae converging towards the apex, with two or three ill-developed growth lines parallel to the girdle. Median valves: Lateral areas distinctly raised and crossed transversely with four rows of pustulose lira
