The following is a resume of the results of an examina- 

 tion recently made by the writer of the collections of Aus- 

 tralasian Polyplacophora under the care of the Laboratoire de 

 Malacologie Hue de Buff on, Paris. 



The writer's warmest thanks are due to Professor Joubin 

 for permission to examine the collections, and to Dr. Ed. 

 l»amy, for not only placing the extensive collections at his 

 disposal, but also for much help in the identification of the 

 specimens from which Blainville and other writers made 

 their original descriptions. 



In offering the within notes on these collections, the 

 writer is conscious of limitations due to the shortness of the 

 time at his disposal entirely precluding the possibility of 

 checking through hie rough notes before transcribing them. 



The fortunate rediscovery of some of the lost types, 

 notably of Blainville and Lamarck, on which so much has 

 been written by Dr. Pilsbry, Mr. Tom Iredale, and others, 

 will, I feel sure, be appreciated by all workers. 



Fairly full notes have been given of a good deal of 

 material of less importance than the types before referred to. 

 This has been done because the writer had an unique oppor- 

 tunity of comparing the specimens with those of his own 

 collection which he brought to Europe for this purpose, and 

 which is undoubtedly the most complete collection of Aus- 

 tralian chitons that has up to the present been made. The 

 references given are not complete, but sufficiently so for the 

 purposes of this paper. As far as possible the notes have been 

 arranged in the order of modern classification. 



Gallochiton dentatus, Spengl., Australe. One specimen 

 on card. On the back is marked ''fulgetrum, Reeve." It is 

 very worn, but I have no doubt it is C . plafessa, Gould. 



Lepidopleurus fodiatus, Rochebr. Type (Bull. Soc. 

 Philom., 1880-81, p. 120). The card on which these shells 

 are mounted is marked "Is. (liadsella) fodiatus, Rochebr." 

 Also, there are several separate valves in spirit marked oli 

 label "Is. tigriivu^, Kraus." Other notes on the label, "New 

 Holland, M.' Verreaux, 1842. Type, M^ 108."
