 1899. Adelactaeon concinna casta, Tate. T.R.S. S.A.^ 

 p. 236. 

 Hab. — Dredged, 38-40 fathoms, sand and shells ; off East 

 Moncoeur Island, Bass' Strait (Challenger) ; Hobson's Bay ; 

 Altona Bay (F. E. Grant) ; Port Phillip ; Western Port. 



Obs. — The type was obtained by A. Adams in the China seas j 

 he also described a species from Moreton Bay as Monoptygma 

 concinna, a very similar shell, and by many considered to be the 

 same, but mentions it as having the outer lip lirate internally ; 

 this character does not occur in any of the specimens that we 

 have obtained. Watson states that the types of M. casta, A. 

 Adams, and M. concinna, A. Adams, are both in the British 

 Museum, and are identical. We follow W. H. Dall in his paper 

 on the Tertiary Molluscs of Florida, Part II., Transactions of the 

 Wagner Institute, in classifying the two foregoing species.
