On the Australian Halivtidte. 51 



describe this latter under the name of H. costata. This is 

 now nearly twenty-three years ago ; but the author takes no 

 notice of this description, although he quotes another from 

 the very same page : neither is the most remarkable distinc- 

 tion of this species alluded to, which in my original descrip- 

 tion is thus expressed — " The interior side is very elegant, 

 being marked by fine lines crossing the sulcation of the ribs."* 

 The locality is stated to be New Holland ; but I believe this 

 is incorrect, never having found it myself there, or seen it in 

 any of the Australian collections. In New Zealand, how- 

 ever, it is met with in a few localities, but nowhere common. 

 I can see no difference between the species figured at PI. 10, 

 fig. 29, under the singular name of H. Enimoe, and that 

 described by me in the Bligh catalogue as 



Haliotis carinata, 



and figured by Martini, tab. M, f. 140, although to neither 

 this description or figure does Mr. Eeeve make any allusion. 

 Dr. Milhgan has fine specimens from the Tasmanian coasts ; 

 but we do not think that it also inhabits New Holland, as 

 here stated. Of that beautiful species 



Haliotis elegans, 

 which is here admirably figured by Mr. Sowerby, I have 

 seen but two specimens, in the collection of my friend 

 G. W. Walker, of Hobart Town, who thinkshe procured it 

 on some island in Bass's Straits. 



The last species we shall notice in detail is the most 

 splendid perhaps of the whole genus, namely, the 



Haliotis iris, 



which, by some most unaccountable mistake, is stated to in- 

 habit Kangaroo Island, Australia. It is well known, however,
