Lima (Luiatula) subaukiculata. Montf. Tlils shell 

 which is also found in the British seas still existini^, and has 

 been collectedbyCumniinginthe Philippines, is a couimon fossil 

 at Table Cape, at le;ist I can discover no diiference in size, 

 shape, makings, etc. We thus have a ^^orld-wide distribution 

 as well as an extensive ran>;e in time. 



Tellina cainuzoica. n.s. I give this name to a shell 

 which has characters slightly ditterent from any existing 

 Australian form, but the number of species is already so 

 great and the ditt'erences so slight that I venture to add to 

 them only with considerable reluctance. The form of this 

 fossil approaches to our T. alhineUa, of which there is a white 

 and pink variety. It is, however, smaller, smoother, and less 

 arcuate with scarcely a percej^tible sinus. 'J'he dimensions of 

 this specimen is transversely 24. Long. 15. Thickness 5. 



Chione propinqua. n.s. Shell small, oval, transverse, 

 equivalve, sub-equilateral, posterior and slightly longer and 

 sub-attenuate, anterior end broadly, rounded, transversely 

 ribbed with many solid, raised, rounded ribs grooved behind 

 and lamellar at each end, ribs striate transversely and between 

 which the sti"ia3 become larger towards the umbonos and 

 finally indistinguishable from the ribs of which there are 18-20 

 in all ; interior finely crenulate right round to the hinge 

 posteriorly, to the umbone anteriorly ; central tooth ])ifid, 

 latei-al, — anterior lamellar and moved outwards ; posterior 

 bifid, muscular impressions scarcely perceptible. Transvei'se 

 length 26. Lat. 4.21. A shell certainly very nearly approach- 

 ing our existing Chione conularis, but less oblique in its shape, 

 size, and almost entirely crenulated margin. 



Vexus (chione) cAiNOzcricA, n.s. suborbicular, inequi- 

 lateral, globosely convex, very finely and closely striate with 

 concentric lines, which here and there become lamellose, 

 lamellae close and more numerous at the anteiior and pos- 

 terior margin, scarcely raised, extremely thin and nearly 

 always broken and incomplete, where there are no lamella3, 

 striae regular and equi-distant, marking lines of growth which 

 seem to overlap each other in regular succession ; anterior side 

 rounded, contracted ; posterior side broadly rounded and very 

 slightly produced ; umbones convex, much incurved and 

 smooth, lunule clearly defined, but not deep, broadly cor- 

 date lamellosely striate and radiating from the um- 

 bones, and finely crenulated on the edge within ; hinge teeth, 

 right valve with one long lateral ridge extending to the ventral 

 margin with a groove between it and the edge, three smaller 

 teeth, the two posterior bifid, the anterior one small, lamellar 

 and oblique ; left valve with a lateral ridge, one thin short 

 curved hinge below the corselet, one broad central tooth ; and
