Show 88 MR. G. F. ANGAS ON AUSTRALIAN MOLLUSCA. [Jan. 1 7, 3. TRITON (CUMIA) SPECIOSA, Angas, P. Z. S. 1871, Ph I. (. 1. A small beautifully sculptured white species, having upwards of twenty varices, and sometimes a pale chestnut band on the last whorl. It appears to belong to that group of the Tritoniida? to which the subgeneric name of Cumia has been given, of which Triton convolutus, Brod., may be regarded as the type. The largest specimen I have seen measures 8 lines. Mr. Brazier obtained it living at Green Point, Watson's Bay, Port Jackson. 4. RANELLA PUSILLA, Brod. P. Z. S. 1832, p. 194. This pretty little species, hitherto known from the tropical Pacific Islands, has been found at Broken Bay (Brazier). Fam. DACTYLID^E. 5. AMALDA CINGULATA. Ancillaria cingulata, Sow. Species Conch, pl. 6. f. 36, 37. Several specimens of this beautiful shell have been met with at Brisbane Water and Broken Bay. It varies in length from 3 to 4-3*- inches. The animal, Dr. Cox informs me, is 10 inches in diameter. 6. OLIVELLA EXQUISITA, Angas, P. Z. S. 1871, Pl. I. f. 2. A charming little species, with three rows of chestnut spots connected by fine undulating lines. Coodgee Bay, New South Wales (Brazier). Fam. VoLUTiD_e. 7. VOLUTA FUSIFORMIS, Swains.; Reeve, Conch. Icon. Voluta pl. 3. f. 6. A broken example of this fine Volute has been found on the beach at Broken Bay-probably its northernmost range. It was hitherto regarded as exclusively Tasmanian. 8. VOLUTA PUNCTATA, Swainson, Zool. Illus. 1st series, pl 161- Reeve, Conch. Icon. Voluta, pl. 21. f. 52. ' The very bad figure given in Reeve, taken from an immature and much worn specimen in the British Museum, gives but a faint idea of this rare shell. Its locality was unknown until very recently, when several examples were obtained by Mr. Brazier from the outer beach at Broken Bay. 9. VOLUTA ZEBRA, Leach, Zool. Miscell. vol. i. pl. 12. f. 1. Port Stephen Heads. The more elongated and closely lined variety, described by Leach as V. lineata, bas been found by Mr. Brazier on the beach at Lake Macquarie. |
