52 On the Australian Haliotidce. 



in these colonies to be altogether peculiar to the islands of 



New Zealand. 



The following species, described as peculiar to Australia 



or New Zealand, I have never seen either living or dead : — 



Haliotis squarrosa Australia PI. 7 fig. 20 



„ ... Fioei New Holland 



,, ... excavata Kangaroo Island... 



„ ... ovina * New Holland and 



Philippine Islands 



„ ... Rquamata N. W. Australia... 



„ ... diversicolor New Holland 



„ ... funebris Ditto. 



„ ... cruenta New Zealand 



„ ... Zealandica Ditto. 



„ ... Dringii N. W. Australia ... 



„ ... Lauta Swan River, N.Hd. 



5, ... Papulata N.Australia 



,, ... StomaticBformis ... New Zealand 



Presuming that the localities of these twelve species are in 

 some degree correct, or at least that they inhabit the Pacific 

 Ocean, we may, with the preceding species, (noticed in detail) 

 take the number to be in all 21, being nearly one-third of 

 all those here described. It consequently follows that the 

 proportionate number of Chitons and of Ear-shells in this 

 part of the world is nearly equal, and that their geographic 

 distribution is in perfect and harmonious union. 



It is much to be regretted that in this monograph of a 

 very difficult and intricate group the author has not been 

 at greater pauis to clear up entangled synonyms, to make 

 the reader acquainted with what other writers had pub- 

 lished on the same subject, and to state with precision 

 and accuracy those few references to other works which he 

 occasionally quotes. There is, for instance, no notice 

 whatever of the admirable figures and descriptions of this 

 genus published by Da Costa and Humphrey in the early 



* I cannot believe that the same species is found in these two widely 

 different localities.
