Take any quantity of Nelson's gelatine, and let it soak for two or three hours in cold water which has previously been saturated with arsenious acid; pour off the superfluous water, and heat the soaked gelatine until melted.To each fluid-ounce of the gelatine add one drachm of alcohol, and mix well; then add a fluid-drachm of the white of an egg; mix well while the gelatine is fluid but cool.Now boil until the albumen coagulates and the gelatine is quite clear.Filter through fine flannel and to each fluid-ounce of the clarified gelatine add six fluid-drachms of Price's pure glycerine, and mix well-Carpenter's Microscope and its Revelations, 3rd edition, p. 775. 9 RECENT BRITISH OSTRACODA.359 The following synopsis of the sections and families here described is given by Sars :-(simple, subpediform, geniculate, clawed) two pairs, the last bent up within the ) at the apex, not very unlike the upper | valves.Postabdomen forming two elon-| Gypprp a, | antenne.Both pairs of antenne either | gated narrow rami, which are usually if ; bearing long setze and adapted for swim-| clawed at the apex.ming, or shortly setose and not used for j PODOCOPA swimming.Mandibles distinct, mostly -three pairs, all ambulatory, much alike c ai strongly toothed at the lower extremity; | in structure, and directed forwards.Post-| @ypyrppalp of moderate size, and bearing a more | abdomen rudimentary, forming two very > yy or less developed branchial appendage.| small lobes.Antenne very little Peal First pair of maxille bearing a large | for swimming, branchial plate.Feet ZB. | ( (one pair only, of singular shape, forming | an elongated, curved, flexible, annulated, | | vermiform appendage, which is spiniferous one branch rudimentary, immo-| towards the apex.Upper antenne large, | bile; the other elongated, cylindrical, | distinctly jointed, geniculate at the base.flexible, many-jointed, armed with | Mandibles proper obsolete.Second pair > | long natatory setze, arranged in a | of jaws bearing a large branchial plate.single series; basal portion very large | Eyes compound, pedunculated, widely and stout, filled with muscular bands.| separated; between the two in front a | Upper antenne scarcely natatory.) large simple eye and a short frontal ae Mandibular palp very large, genicu-tacle.Lary ANONOD !late, ibpeditornn: destitute of a bran-( 'MYODOCOPA.chial appendage.First pair of jaws | two pairs, the posterior very small and ) without a branchial plate.Post-| rudimentary; the anterior provided, like abdomen divided into two broad | the second pair of jaws, with a small, pee which are unguiferous behind.lobed branchial plate.Upper antenne of | Concna-{ CypRIDI-NIDA.two-branched, NE OSTRACODA.Lower antennze Ne eet the female small and weak, immobile and { crapm.J indistinctly jomted.Mandibles distinct.No eyes.Frontal tentacle very large, and mostly dilated at the apex.y) | natatory, not geniculate, ending in a lash of long setee.Mandibles distinct, palp | short and scarcely pediform, provided with a small branchial appendage.Two | Poryco-| CLADOCOPA pairs only of thoracic appendages; the anterior large, bifid, natatory; the poste-( Pipm.( ~ o t e e e rior membranaceous and branchial.yes wanting.Postabdomen divided into | | two short laminze, spinous behind.flattened, similar to the feet of the Copepoda, basal portion biarticulate and geniculate; branches flattened, composed of few joints, and hearing numerous setee on both margins.Upper antennee very large and strong, many-jointed, geniculate at the base, shortly spiniferous.Mandibles small and weak, palp large.Three pairs only of thoracic appendages, all maxilliform.Palp of the mandible + Se 2 l PLATYCOPA.and first jaw bearing internally a comb of large sete.First and second pairs of | 'TMM1P#jaws provided with a large branchial plate; third pair rudimentary in the female, in the male well developed and prehensile.Postabdominal rami small and both branches well developed, moveable, and natatory.Upper antennz also | { narrow, distinctly separated, and spiniferous at the apex.Section I.
