M. Diemenensis ; the true M. multistriatus is a very different 

 shell ; and Hutton's record of M. disruptus for the Wanganui- 

 Pliocene relates to M. multistriatus. M. disruptus is sufficiently 

 distinct from M. Diemenensis to take specific rank. The generic 

 name Cytherea, Lamarck, is replaced by Meretrix. 



Cypricardia rostrata, Lk. !, which is attributed to Kangaroo 

 Island, is labelled in the Paris Museum with the locality of New 

 Holland. 



Lucina lacteola, Tate, nom. mut. 

 L. lactea, A. Adams, non Lamarck. 

 L. concentrica, Adams and Angas, 1863, non Lamarck. 



The British Museum records show that L. lactea has precedence 

 over L. concentrica, and that the two names refer to the one 

 species, but as the employment of either names has previously 

 been in use and continues so, it becomes necessary to affix a new 

 specific denomination. 



Axinus flexuosus, Montague. A British species now known 

 in New South Wales (Brazier), Tasmania (Petterd ! and May !) r 

 and South Australia, St. Vincent Gulf (Dr. Verco !). 



Lucina minima, Ten. -Woods !, Proc. Roy. Soc. Tasmania for 

 1875, p. 162 (1876), antedates L. Tatei, Angas, by two years. 



Lucina cumingi, Adams and Angas. This Divaricella may 

 not be L. quadrisulcata, D'Orbigny, and if the distinction is 

 valid, then L. Cumingi comes to be employed for the Australasian 

 shell. 



Crassatella micra, Verco, Trans. Roy. Soc. S. Aust., vol. 

 XIX., pi. i., f. 3. 



Crassatella producta, Verco, op. cit., pi. i, f. 2. 



Mytilicardia crassicostata, Lamarck ! (Cardita), is rightly 

 identified by comparison with the type. 



Barbatia Carpenteri. 



The following are additional synonyms : — Area trapezia and 

 A. fasciata, Ten. -Woods in Hobart Museum. 



Barbatia laminata, Angas !, is a mere synonym to B. squamosa, 

 Lamarck !, as also A. McCoy i, Ten. -Woods. 



AxiNiEA radians, Lamarck (Pectunculus) I. Pectunculus 

 obliquus, Reeve !, is a synonym, and moreover the specific name 

 is preoccupied by Def ranee, 1826, and Lea, 1833. 



AxiNiEA striatularis, Lamarck (Pectunculus) I This is the 

 same as P. radians of my "Revision," IX., p. 103. The type is 

 from King George Sound ; the examples in the British Museum 

 are labelled from Swan River. 



Limopsis Forskali, Adams !. The Limopsis Belcheri of my 

 Revision, IX., p. 104, wherein I had adopted McCoy's identifica- 

 tion, is certainly not that species !. It approaches best to L. 

 Forskali, but whether L. Macgillivrayi be the more appropriate 

 designation I cannot say, not having seen that species.
