710 NOTES AND EXHIBITS. 



19. Loricella Angasi, Ad. 



20. Liolophiira Gaimardi, Blainv.; another common form formerly 



recognised in Australian Collections as Chiton piceus. 



21. Onithochiton rugulosus, Angas. 



22. Onithochiton quercinus Gould. 



Mr. Pilsbry does not include 0. Lyellii, Sowb., which he seems 

 to look upon as probably a variety of one or other of the two 

 Onithochitons enumerated. My own impression is that the three 

 are all one and the same variable species. 



To Mr. Pilsbry's list I have to add : — 



23. Lorica volvox, Reeve. 



2-1. Chiton Sinclairi, Gray; or what at present I take to be such. 



The collection on which Mr. Pilsbry's list is based consisted 

 very largely of specimens sent to him by myself. By an accidental 

 omission L. volvox Avas not included amongst them; it has been 

 previously recorded as occurring in Port Jackson by Angas, and 

 it is in most of the local private and pul)lic collections."
