Nucula 'jigantea, Etheridge, Quart. Journ. Geol. Soo., 1872, xxviii,, p. 341, t. 20, f. 4. 
Sp. Char. Shell ovately oblong ; dorsal margin nearly horizontal ; ventral 
margin nearly semi-circular ; umbones placed very anteriorly and nearly straight ; hinge- 
teeth thirteen or fourteen, on posterior side, and five or six on anterior side of umbo. 
{Etheridge.') 
Obs. The ligamentary pit in this species is large and spoon-shaped, and directed 
towards the posterior end. One specimen examined possessed sixteen teeth on the 
posterior hinge, and another from Port Curtis only ten, but this may depend on 
preservation. The exterior was ornamented with fine concentric lines. 
Loc. Maryborough {The late E, Daintree; Messrs. T. W. E. David and G.

Station, Port Curtis {W. H. Bands).

Nuculaka (? Yoldia) Baudsi, sp. nov., PI. 26, fig. 10. 
Sp. Char. Shell elongately ovate, rather tumid, moderately large, rostrate 
posteriorly. Cardinal margin or hinge-line somewhat convex in front, excavated or 
concave behind, with about fourteen teeth both on the anterior and posterior sides. 
Anterior end rather produced ; anterior and ventral margins rounded. Posterior end 
bluntly rostrate, curved upwards. Umbones sub-central. 
Obs. The surface markings and the pallial line are not visible, but I believe the 
species is refei’able either to Niiciilana or Yoldia. Tt is allied to such as Leda protexta, 
Gabb,* and Yoldia scaphuloidea, Stoliczka,t more particularly the latter, but differs in 
size and in having a more acute rostrum. 
The siiecics is named in honour of Mr. W. H. Bands, Assistant Government 
Geologist of Queensland.

Sp. Char. Shell elongated, length nearly double the height ; umbones nearly 
central, nearer anterior than posterior margin ; teeth very numerous on both sides of 
umbo, anterior twelve or tliirteen, posterior fifteen. {Etheridge.) 
Ohs. In form this species seems to approach much nearer to H. and A. Adams 
genus Adrana than either to Leda or Yoldia. The resemblance to Leda scapha, d’Orb., 
does not appear to be so aj/parent, as stated by Mr. Etheridge. As regards Yoldia 
scaphuloidea, StoL, of the Arrialoor Group of India, the likeness is greater, but the two 
shells are clearly distinct. When perfect, the anterior margin is regularly rounded, and
