MOLLUSCA. 97 



16. Tapes malabarica. 



Chemnitz ; Miner, Monog. Tapes, Novitat. Conch, p. 34, pi. 10. 

 figs. 3-3 d. 



Hah. Port Molle, 14 fins. (Coppinger) ; Malabar, Molucca and 

 Philippino Islands (Rimer). 



17. Tapes variegata. 



Sowerby ; Homer, I. c, supra, p. 78, pi. 27. figs. 2-2 e. 



Hah. Port Curtis, 7 fins. (Cvppinger) ; Philippine Islands and 

 Japan (Itbmer). 



18. Tapes araneosa. 



Venus araneosa, PhUippi, Abbild. vol. iii. p. 2-">, pi. 7. fig. 6. 



Tapes araneosa, Homer's Monogr., Novitat. Conch, p. 53, pi. 19. fig. 1. 



Hah. Port Darwin, N.W. Australia, 8-12 fms. 



The locality of this species I believe has not hitherto been re- 

 corded. In the single specimen before me the umboncs are all but 

 terminal, so that the anterior end is even more perpendicular than 

 as represented by Dr. Homer's figures. T. deshayesii is not unlike 

 this species as regards its general form ; but the anterior end is 

 hardly so short, and the concentric sculpture decidedly coarser. 



19. Tapes (Textrix) textrix. 



Venus textrix, Chemnitz. 



Hah. Port Jackson (Coppinger). 



Two young examples of this well-known species are of a buff colour, 

 mottled with bluish white at the umbones, and spotted with red- 

 brown on the dorsal margins. 



20. Venerupis crenata. 



Lamarck; Delessert, Recueil, pi. 5. fig. 2; Pfeiffer, Con.-Cab. pi. 31. 

 figs. 22, 23 ; Sowerby, Conch. Icon. fig. 3; Reeve, Conch. Icon. fig. 5 

 (as Cypricardia serrata). 



Hah. Port Jackson (Coppincjer). 



21. Trapezium vellicatum, var. 

 Cypricardia vellicata, Reeve, Conch. Icon. pi. 2. fig. 7. 



Hah. Port Darwin, 8-12 fms., bottom mud and sand (Coppinger)', 

 Philippine Islands (Cuming). 



The ]S T orth-Australian variety of this species is peculiar on account 

 of the absence of the coloured rays which distinguish the typical 

 form.
