1861 T. R. Jones Gen. Outl. Animal Kingdom (ed. 3) xiv. 418 At certain times, however, the Daphnia may be seen with a dark opake substance within the back of the shell, which has been called the ephippium, from its resemblance to a saddle... The ephippium is really only an altered part of the carapace.

1877 T. H. Huxley Man. Anat. Invertebrated Animals vi. 287 The ephippium sinks to the bottom, and, sooner or later, its contents give rise to young Daphniæ.
