Edwards; with a de^scription of two new species. By W. Baird, M.D., E.L.S. &c. (With two Plates.) The genus Cypridina was founded by M. Edwards in 1838, in anote to the second edition of Lamarcks Hist. Nat. An. sansVertebres/ and was afterwards more fully detailed in the third vol.of his ^ Hist. Nat. des Crustacees. The animal resembles a gooddeal in its general form and structure that of the genus Cypris,From his observations however it appears to have two eyes, di-stinct from each other; two pairs of antennae, both pediform; onepair of natatory feet, and a peculiar organ apparently for support-ing the ova, similar in purpose to, but differing in structure from,the second pair of feet in the Cypris. In 1840 M. Philippi pub-lished a paper in the sixth vol. of the Ann. and Mag. Nat
