194 MR. G. F. ANGAS ON AUSTRAIiTAN MOLLUSCA. [Feb. 14, 



This Me?«wm-shaped, smooth, black species is not uncommon 

 under stones at low water, in some parts of Port Jackson. It belongs 

 to the same group as 31. glabra, which represents it in South Au- 

 stralia and Tasmania. Length 2 inches 8 lines. 



46. MiTRA SOLIDA. 



Mitra solida. Reeve, P. Z. S. 1844 ; Conch. Icon. Mitra, pi. 3. 

 f. 18. 



Of this very rare Mitre, which is of a fulvous-bay colour, irregu- 

 larly flaked with white, a single specimen, habitat unknown, was 

 described and figured by Reeve, from the collection of Mr. Norris. 

 A second example, in a living state, was dredged by myself off 

 Middle Head, Port Jackson, in 5 fathoms. It was also obtained in 

 6 fathoms in Port Jackson, by Mr. MacGillivray, during the voyage 

 of H.M.S. ' Rattlesnake,' and erroneously referred to as M. sordida 

 in Prof. Forbes's paper on the "Mollusca" in the Appendix to the 

 accoiuit of that voyage. Length 1 inch 6 lines, 



A7. *MiTRA (Cancilla) strangei. 



Cancilla strangei, Angas, P. Z. S. 1867, p. 110. 



A pretty little fusiform white shell, with the whorls ridged and 

 cancellated. It somewhat resembles Mitra isabeUa in miniature. 

 Dredged in Middle Harbour. It has also been found at Moreton 

 Bay. Length 7 hues. 



Subfam. Columbellin^. 



48. COLUMBELLA VERSICOLOR. 



Columhella versicolor, Sow. P. Z. S. 1832, p. 119 ; Reeve, Conch. 

 Icon. pi. 11. f. 51 a, b. 



Under stones at low water in Port Jackson. It is also found in 

 New Caledonia and Woodlark Island. Length | inch. 



49. CoLUMBELLA (MiTRELLa) SEMICONVEXA. 



Buccinum semiconvexum, Lam. Anim. sans Vert. x. p. 171 ; Reeve, 

 Conch. Icon. pi. 18. f. 95 a, h. 



Common under stones about Watson's Bay. The Port Jackson 

 specimens are smaller and more elongated than those from Tasmania 

 (which are typical), and have not the same flesh-coloured tinge. 

 This is a very variable species ; and it is probable that the C. rosacea 

 and C. saccharata of Reeve are only extreme pink varieties from 

 Tasmania. An orange variety occurs at Lacepede Bay, in South 

 Australia. Length 9 lines. 



50. Columbella (Mitrella) australis.
