ExplaiiJitioii of tlie Pl.ates. 



On account of the fact that the plates were printed, witliout proofs of tlieni having been submitted to 

 the author, a few errors, fortunately of minor importance, have crept in, to which attention is called herewith. 

 In Pi. Ill the figure numbers were forgotten. Fig. 1 is the upper, fig. 2 the lower tigure. In PI. V some of 

 the holes in the valves of pedicellariae represented there have become unduly black. This is especially the 

 case in fig. G (at the upper part of the apophysis) and fig. 13 (near the outer end); to a less degree it is 

 the case in figs. 2, 5, 8, 18 and 19.
