The genus Amathia has formed the subject of special Memoirs by Tenison-Woods ") 

 and MacGillivray 3 ) ; the former author giving a valuable account of its history, and the latter 

 describing a number of Australian species. It is well represented on the Australian coast, but 

 the 'Siboga' collection includes only two species.

The following records may belong to this species; but the amount of information given 

 is insufficiënt to enable any certain statement to be made : —

1) Miss Jelly (1889, p. 279) and NlCKLES and Bassler (1900, p. 510), in their bibliographical lists, mention the title of a 

 paper, without further reference, supposed to have been published by Lamouroux in 1910; and Tenison-Woods (1880, p. 97) gives the 

 title in more detail. This paper appears not to exist. It is true that Lamouroux himself (1824, p. 43) states that he "proposed" the genus 

 Amathia in 1910: but in his "Histoire des Pol. Cor. Flex.", 1S16, p. 187, he gives 1812, with the reference cited above, as the date of 

 the introduction of that genus; and in the Preface (p. vi) of the same work he explains that his memoir was presented to the French 

 Academy in 1S10, but actually appeared two years later (1812).
