Cithara cotnpta, Ad. & Ang. P. Z. S. 1863, p. 419, pl. 37. f. 5. Dredged in Port Jackson. Found also in South Australia. Length 6 lines. 111. * MANGELIA PICTA. Mangelia picta, Ad. & Ang. P. Z. S. 1863, p. 419, pl. 37. f. 7. Prettily banded with purple and white, on a fulvous ground. Dredged in Port Jackson. Length 6 lines. 112. * MANGELIA LETOURNEUXIANA. Pleurotoma letourneuxiana, Crosse, Journ. de Conch. 1865, p.425, pl. 11. f. 7. A n elegant fusiform species, longitudinately plicately ribbed and transversely striated. Dredged in Middle Harbour. Length 6 lines. Fam. CONID^E. 113. CONUS MACULOSUS. Conus maculosus, Sow*. C. maculatus, Sow. Thes. Conus, pl. 13. f. 296. In the 'Conchologia Iconica' M r . Reeve figures this species as "var. b " of C. anemone, Lam. (see pl. 25. f. 139 a). It is, however, a very distinct species, as a comparison of a number of specimens in various stages of growth tends to prove. C. maculosus is a nearly smooth, thin, peculiarly inflated shell, richly mottled with purplish brown, and attains a larger size than C. anemone, which is of a true conical form, more solid, finely transversely striated, with an elevated spire, and splashed with rose-brown or orange. C. anemone, moreover, is an inhabitant of South Australia, and never occurs in Port Jackson, where G. maculosus is to be found under rocks and large stones, at low spring tides, in many situations. At Watson's Bay I have taken as many as ten living specimens from beneath one stone. This species is found in the Philippine Islands, on the authority of the late Mr. Cuming. Length of the largest Port Jackson specimen 2\ inches. 114. CONUS JUKESI. Conus jukesi, Reeve; Sow. Thes. Conus, pl. 13. f. 297. A very angular species, peculiarly mottled with bluish grey and olive, first met with by Mr. Jukes during the voyage of H.M.S. • Fly' on the north coast of Australia. I have obtained several fine living specimens (one of which was perfectly white) in Port Jackson, in company with C. maculosus. Its maximum size is 1 inch 4 lines. |
