Show 1871.] MR. G. F. ANGAS ON AUSTRALIAN MOLLUSCA. 89 10. VOLUTA NUCLEUS, Lam. Anim. sans Vert. vol. x. p. 405 ; Reeve, Conch. Icon. Voluta, pl. 18. f. 41. Newcastle, New South Wales (Brazier). Fam. MITRID_E. 11. M I T R A GLABRA, Swains. Exotic Conch, pl. 24. Botany Bay. Occurs also in South and Western Australia. 12. MITRA VARIABILIS, Reeve, P. Z. S. 1844, p. 175. A species of a brownish-olive colour, with a zone of interrupted grey markings near the middle of the last whorl, and a few irregular flakes of the same colour descending from the sutures. The whorls are more or less encircled by finely punctured striae. Length 1-L inch. Under stones at Double Bay (Port Jackson) and Brisbane Water (Brazier). The shells under the above name in the Cumingian Collection in the British Museum are identical with M. cglindrica. I cannot find Reeve's original type; but the specimens sent me by Mr. Brazier agree with his description of M. variabilis. Subfam. CoLUMBELLINiE. 13. C O L U M B E L L A INTERRUPTA, Angas, P. Z. S. 1865, pl. 11. f. 9, 10. This beautiful little species may be known by its two green finely pencilled and scalloped bands. The type specimen was dredged by me at Yorke's Peninsula, in South Australia. Mr. Brazier has recently obtained it in Port Jackson. 14. COLUMBELLA (MITRELLA) BICINCTA, Angas, P. Z. S. 1871, Pl. I. f. 3. A smooth fusiform species, distinguished by having two opaque white bands articulated with brown above and below the sutural margin. Dredged in Watson's Bay, Port Jackson. 15. COLUMBELLA (MITRELLA) ATTENUATA, Angas, P. Z. S. 1871, Pl. I. f. 4. An elegant little species, remarkable for its very elongated form, and its simple bands of light and dark brown. Dredged near the •*** Sow and Pigs," Port Jackson (Brazier). 16. COLUMBELLA (ANACHIS) ATRATA, Gould, Otia, p. 131. In my "List of Port-Jackson Shells" (Part I. No. 55) I erroneously gave the name C. lentiginosa, Hinds, to this species, which is a very distinct shell, and comes from the Gulf of Nicoya. C. lentiginosa must be cancelled as an Australian species. C. atrata is found under stones at Mossman's Bay, Port Jackson. |
