MOLLU80A. 93 



Four specimens from the above localities appear to agree fairly 

 with the superficial description given by the zoologists of the 

 ' Astrolabe,' ■whose examples were obtained at Port Dorey in New- 

 Guinea. 



III. CONCHIPERA. 



1. Teredo (Xylotrya) antarctica ? (Plate VII. figs. E-E 2.) 



Hutton, Cat. Marine Moll. New Zealand, 1873, p. 69 ; Journ. de 

 Conch. 1878, vol. xxvi. p. 43 ; Man. N. Z. Moll. 1880, p. 183. 



Hab. Auckland to Dunedin (Hutton) ; Port Denison, Queensland 

 (Ooppinger). 



The specimens from Port Denison, which may belong to this 

 species, are very like T. norveyims and T. palmulata externally. The 

 sculpture is similar, but the notch or angle in the anterior side is 

 not quite so deep as in the former. The interior of the valves has 

 not a distinct ridge marking off the posterior lobe. The pallets, 

 wanting in the specimens before me, are said to be "elongate, 

 slightly curved, penniform." 



2. Saxicava arctica. 



Mya arctica, Linn. 



Hah. Port Jackson (Ooppinger). 



Four specimens from the above locality and others in the British 

 Museum, also from New South Wales, I am unable to separate frbm 

 this northern form. Dr. Gwyn Jeffreys and others have also failed 

 to distinguish Australian from Arctic examples. 



3. Venus lamellaris. 



Antigona lamellaris, Schumacher, Essai,y. 165, pi. 14. fig. 2. 



Venua lamarckii (Gray), Seeve, Conch. Icon. figs. 39 a, b.

11. 

 Var.= Venus nodulosa, Sowerhy, Thes. Conch, pi. 153, fig. 16. 



Hah. Friday Island, Torres Straits. 



A single valve from this locality is rather longer than usual, 

 having a length of 53 millim. and a height of 38. 



4, Venus toreuma,
