“…The shape and dimensions noted in this study for C. stutchburyi are very similar to those reported for C. cancel/ata reared in North Carolina (La Barbera & Chanley 1970) (1967) should therefore be applicable to C. stutchburyi.…”

“…DISCUSSION AND CONCLUSIONS Temperature fluctuation has been used successfully to induce spawning of Venus striatu [a, V. verrucosa, v. fasciata, Venerupis pullastra, and V. aurea (Le Pennec 1973), Tapes sem.idecussata and Mercenaria species (Loosanoff & Davis 1963, Bardach et al RV 1972 , and Chione cancel/ala (La Barbera & Chanley 1970). It has not been found effective, however,in Pitar morrhuana (Loosanoff & Davis 1963) , Chione cancel/ata (D'Asaro 1967), Chione stutchburyi (this study), and many other venerids (Chanley, unpubl.…”

“…The broadly rounded umbo noted in C. stutchburyi is characteristic of the Veneridae (La Barbera & Chanley 1970), as is the general hinge structure, the rcugh provinculum which gives the impression of numerous incipient teeth, and the long tooth of the anterior left valve provinculum which opposes a solid lateral tooth of the right anterior shoulder on closure (Rees 1950).…”

“…The success of practical identification of venerid larvae in the plankton depends on description of all other local species. In comparison with these, the general dimensions and especially the hinge length (La Barbera & Chanley 1970) and minor dentition of the provinculum should allow recognition of Chione stutchburyi larvae.…”

Larvae of the New Zealand cockle Chione stutchburyi (Wood, 1828) reared to settlement in the laboratory are described. They are characterised by dissimilar shoulders with a large, broadly rounded anterior shoulder and end, and broadly rounded umbo, typical of the Veneridae. Setting occurred after 20 days at a minimum length of 180 pm. Shell dimensions increased linearly during larval development but hinge length did not. The L:H ratio decreased from 1.27 at L = 100 to 1.1 at L = 200 and .the L:D ratio from 1.95 at L = 100 to 1.59 at L = 200. An SEM study revealed that the larval hinge is characterised by a toothed provinculum forming a broad medial projection on the right valve, opposing two projections on the left valve. Conspicuous flanges on the anterior and posterior shoulders of the left valve fit into corresponding grooves of the right valve.

“…The ability to delay settlement is prevalent in marine bivalves (Thorson 1950;Loosanoff & Davis 1963;Bayne 1965) and it is considered that the retention of the pediveliger condition may increase the chance of the larvae finding a suitable settlement substrate. Hov/ever, there is some evidence that in culture, larvae may settle at smaller sizes then those commonly found in plankton (compare the sizes given by workers who have studied larvae isolated from the plankton with settling sizes obtained in the laboratory) (Chanley 1965;Loosanoff et al 1966;La Barbera & Chanley 1970). Probably the presence of a substrate, the culture vessel, stimulates settlement that might be delayed in the absence of a substrate.…”

The larval shells of Paphies ventricosa, reared to settlement in the hatchery, are similar in longitudinal profile to shells of some other mactracean larvae; the umbo-stage larval shells are nearly round with the anterior margin less broadly curved than the posterior margin, the anterior end is longer than the posterior end, and the umbo is broadly rounded. Straight-hinge larvae had total lengths up to 149 |xm, and total heights up to 126 H-m, and umbo larvae had total lengths up to 320 H.m, and total heights up to 282 |xm. The larvae settled in about 22 days at a size of about 270 u,m. The larval hinge structure bears some similarities to those of other mactracean larvae.
