I must mention that Bigelow's figure (191 ib; pi. 19, fig. 2) of a nectophore does not perhaps give a very good idea of the typical form. In fact for years this figure misled me into mis-identifying the juvenile nectophores of Agalma okenii, which have only one ridge on the lateral facet (see p. 64) as those of A. elegans. I give this warning because Bigelow's famous report is a standard reference work, and his figure is the only one likely to be used by planktonologists. Leuckart (1854; pi. 12, fig. 22) illustrated well the characteristic dorsal view, and showed its difference from that of Stephanomia rubra, which he illustrated on the same plate in fig. 12.
