The exposure of the shell and production of mantle in a tube 

 connects this with the European T. depilans Linn., and con- 

 sequently places it in the typical section of Tethys as restricted 

 by Pilsbry.* 



The shell does not differ from that of A. brunnea Hutton,t nor, 

 if T can trust my recollection of the type, from that of A. tryoni 

 Meinertz. Probably these and others will be reduced to the 

 synonymy of 2\ no^-folkensis when they are carefully re-examined. 



Cassidula zonata H. and A. Adams. 



(Plate xxxiii., fig.30.) 



No illustration has yet appeared of this species, a deficiency 

 which I now supply. The animal occurs under sticks and stones 

 near high water mark along the edge of mangrove swamps, 

 associated with Ophic'ardelus, Assiminea, Tatea and Salinator. 

 It was originally described from Sydney. | A better account 

 was afterwards framed by PfeifFer.§ It was redescribed by 

 Tenison Woods|| as Auricula {Rhodostortia) dyeri^ from the north 

 coast of Tasmania. This name was recognised as a synonym by 

 W. F. Petterd.U The species was reported from Port Mackay, 

 Queensland, by Schmeltz,"*^"^ but I have not myself traced it north 

 of Moreton Bay. From the last monograph of the Auriculidse 

 in the Conchylien Cabinet, the species has been entirely omitted. 

 The example figured is from the Lane Cove, and is 10 mm. in 

 length. 



Pinna serrata Soweriiy. 



The description of this species by G. B. Sowerbyff preceded 

 the figure! I by a few months. No locality was given in the first
