107 DESCRIPTION OF A NEW SPECIES OF ASTRA LIUM FROM KEW BRITAIN. Bv Chakles Hedley, F.L.S., and Arthur Willey, D.Sc. (Plate XII.) The following species was dredged up by one of us in Talili Bay, off the north-east coast of the Gazelle Peninsula, New Britain, in 30-40 fathoms on a shelly floor, in company with species of Xenophoruft, EaneUa, Oniscia, Pleurotoma, Fusus, Nassa, Conus, <tc'. The entire material at our disposal consisted of some three dozen specimens, and was obtained in one haul of the trawl. The stages of growth exhibited ranged from young shells about 16 mm. in diameter, inclusive of spines, to adult shells of some 45 mm. in diameter. This handsome shell is nearest allied to the well-known Japanese species, A. triumphans, from which it differs chiefly by a reduction of the peripheral spines in the adult and in the greater number of spines. Adopting Pilsbry's classification as given in the Manual of Conchology, Vol. X., it should enter the sub-genus GuUdfordia of Gi'ay. Description of Sj^ecies. ASTRALIUAI MONILIFERUM, n.sp. ShrJI. — Low, trochiform, imperforate. Colour. — Light purplish beads on a ground of old gold, with a metallic lustre; paler below.
