MOLLUSCA.-HEDLEY. lOI 



Already from Australia there are recorded P. Jiemipsila, 

 Tate, from the Tasmanian Eocene, and recent P. corolla, 

 \'erco, from South Australia ; P. demissa, Hedley, now 

 recorded from South Australia in association with P. fuin- 

 urium, and previously from New South Wales, Victoria and 

 New Zealand; P. galerita, Hedley. from Queensland; P. 

 harrissoni, Beddome, from Tasmania, Victoria and New South 

 Wales, and P. kesteveni, Hedley, from New South Wales. 

 The novelty belongs to the section Fissurisepta now first 

 represented in Australasia. 



Hub. — Several specimens from loo fathoms, forty miles 

 south of Cape Wiles. 



MoNiLEA oi.EACEA, Hedley & Petterd. 

 Monilea oleacea, Hedley & Petterd, Rec. Austr. .Mus., vi., 

 1906, p. 215, pi. xxxvii., fig. I. 

 Some broken but recognisable specimens of this species 

 were taken in 100 fathoms, forty miles south of Cape Wiles. 

 The type was from 250 fathoms outside Sydney, so the 

 present record extends it to another region. The specific 

 name appeared in the description by a misprint as "o/eafa," 

 but was spelt correctly on the previous page 214 and in the 

 explanation of the plate. 



GiBBULA OCELI.INA, Sp. UOV. 



(Plate xviii., fig. 15.) 



Shell small, solid, imperforate, conical, with gradate spire, 

 prominently keeled at the periphery and again at the shoulder. 

 Colour: Below the periphery uniform buff, above it broad, 

 radial stripes of buff pink, alternate with white. Along the 

 periphery are pairs of dashes of madder brown, sometimes 

 these enclose a tinted space and have a background of opaque 

 white, thus assuming an ocellated aspect ; apex pink. Whorls 

 five. Sculpture : Base with seven fiat evenly-spaced concen- 

 tric riblets, a strong, revolving cord defines the periphery 

 and ascends the spire. The last and penultimate whorls have 

 four spiral riblets above the periphery, the uppermost 

 stronger and forming the angle of a subsutural shelf. Upper 

 whorls smooth. Aperture round, outer tip simple, dentate by 

 the spirals, columella perpendicular. Length 3, major diam. 

 3, minor diam. 2'5 mm. 



The profile recalls that of G. coxi, Angas, but by the sum 

 of its characters this comes nearest to G. tiheriana, Crosse. 

 From that the angulation and smaller size distinguish the 

 novelty.
