or only as regular dots around the inner margin, or as short 

 radial brown lines at the internal periphery, or as a continu- 

 ous brown border. Some are uniformly chestnut brown. One 

 form has abundant colour-marking, which may begin at the 

 apex as six to eight rays, tending to break up into tessella- 

 tions as they widen. This variety is often slightly polygonal 

 instead of round, the angles being in the white rays ; but it 

 grades into the ordinary form.

The type locality of A. flammea, Q. and G., is Hobart- 

 town, and the type dimensions are small, 5 lines by 4 by 2J 

 high. 



The type locality of A. crucis, Ten. -Woods, is Tasmania, 

 and its dimensions are 31 mm. by 31 by 19 high. Ten.- 

 Woods described this as a distinct species, but Tate and May 

 and Pritchard and Gatliff unite them. 



Ten. -Woods refers to Patella cruciata, Linne, as distinct 

 from his A. crucis, because the former has "a white cross on 

 a brown ground," instead of a brown cross on a white ground, 

 and Pritchard and Gatliff agree. But Tate and May unite 

 them, and make A. cruciata, Lin., the specific name, and 

 the other two synonyms. I keep them distinct. Ten. -Woods 

 also leaned to the identity of A. f.ammea, Quoy and Gaim- 

 ard, and A. suhundvlnta, Angas, and Pritchard and Gatliff 

 unite them. Shells collected by me and identified by Angas's 

 type in the British Museum have not been yet graded into 

 Quoy's species, and are regarded as distinct.
