topets in aU extra-tropical Australia. Ribs about 17, interior wHte and 

 brown stained. Long. 32, lat. 26, alt. 10. 



AcM^A CANTHAEUS. ^fifiw, /co»., pL 4, j^Qf. 131. Ovate, smooth, thin, 

 convex, apex anterior and generally corroded, smooth, reticulated black 

 and white ; interior like tortoise shell. Long. 24, lat. 19. Common in 

 Australia and New Zealand. 



AcMiBA FLAMMEA. Quoy and G., Vol. de VAst, Vol. 3, p. 354. This 

 is probably the same as A. subundulata, Angas, Zool. Proc, 1865, p. 155. 

 Somewhat high, apex anterior, faintly ribbed, white with brown striae, 

 often radiating in the form of a cross. 



AcsLEA coNoiDEA. Quoy, Voy. de VAstrol., Vol. 8, pi. 71, jigs. 5 to 7. 

 A small, high, conoid shell, generally eroded ; apex very obtuse. Long. 10, 

 lat. 8, alt. 7. Common, S. and E. 



AciiffiA PETTERDi. Tenisou- Woods. 



AcM^A ALBA. Tenison- Woods. 



Patella aculeata. Beeve, pi. d2,Jig. 90. A deeply convex shell, rayed 

 with many ribs, scaly or prickly and narrowly compressed. Recherche Bay, 

 common. Reeve gives no habitat for this shell, which is also found in Port 

 Jackson ; generally covered with harsh brown spongy tissue, not unlike 

 some algse, but which may be an appendage to the animal. Long. 40, 

 lat. 33. 



Patella TEAMOSERiCA. Marty n, Univer. Conch., ed. Chem.^pl. 5, fig. 3, 

 (pi 16 in original). Ribs close set, obscurely nodosely tuberculated 

 yellowish orange or vermilion, and rayed with black, with white spots on 

 the interstices, interior bluish white, silky or metaUic at the margin. By 

 transmitted light distinctly coloured crimson and yellow. Long. 57, lat. 50. 

 Generally depressed, but this varies as well as the shape of the shell, which 

 is oblong to orbicular. Common, and in AustraHa and New Zealand. A 

 most variable shell in size and coloring. I have found every size, and 

 almost every color, especially in the interior, which ranges from pale indigo 

 to golden. In some there is no spathule, or it is black or blue and varied in 

 every way. The most constant characters are, the silky lustre of the interior, 

 and the crimson streaks on orange ground as seen by transmitted light. P. 

 limbata, Phil. , is a, ajaonjm, or, a,t best, a N. Australian variety, it is a 

 (Philippi, Abbild. in Besch., Conch., pi. 3, fig. 1) subconoid shell, with 

 wide radiating ribs indistinctly noduled, interstices narrow and black, deep 

 orange exterior, interior orange at the margin, blotched with black, nucleus 

 blue. Long. 55, lat. 45. Common. I regard this shell as a variety or not 

 even a variety of the preceding. The somewhat broader ribs may dis- 

 tinguish it. 



Patella decora. Philippi, Icon. pi. 3, fig. 13. A peculiar semi- 

 globose ribbed form, with apex very much incHned to the anterior, blotched 

 black and blood-like. Rare, and in New Zealand. Long. 40, lat. 32, though 

 the Tasmanian identification is very doubtful. 



Patella USTULATA. Reeve, Icon., pi. Zl, fig. 88. Depressed apex, sub- 

 marginal, coarsely ribbed, with many fine riblets in the interstices, scorched 

 with rich brown, often corroded, white inside with narrow fringe of brown 

 and yeUow. Long. 35, lat. 29. Somewhat common, S. and E. Coasts. 

 Reeve's species described from worn shells.
