INVESTIGATIONS ON PARAGUAYAN BATRACHIANS. ál 5 Coloration. The young specimen pale reddish brown above with indistinct darker not confluent spots and indistinct cross-bars on the limbs. A blackish brown lateral band extends from behind the eye near to groin, sharply edged above, paler and more irregularly below ; from this band below the conceiled tympanum runs a more or less distinct dark branch vertically to the angle of the mouth, edged on both of its sides with white or pale brown.* Edge of the upper lip dark brown with more or less distinct irregular vertical bars ; canthus rostralis more or less pronounced dark brown. A round black inguinal spot absent. Beneath greyish white, throat and breast mottled with brown. The older specimen similar, but nearly uniform greyish rose coloured above, only 011 the posterior part of the back with obliterate light brownish markings and a trace of cross-bars on the hind limbs ; beneath white with some brown spots on the throat, breast and belly. The structur of the sternal apparatus (pl. XIII. fig. 6) characterized by a semiossified omosternum and a bifid bony style of the stern u m furnished in front with a pit, every branch o f i t s endings in an anchor- shaped cartilaginous plate. This forked structure of the sternum was not known in literature up to this time, 1 think, however, that it is of great importance, because some Paludicola — for example Paludicola fuscomaculata STDR. (pi. XIII, fig. 7) — have the same structure, but others as Paludicola Bihroni TSCHIDI (pl. XIII, fig. 10) — possess a two-jointed simple bony style and a simple cartilaginous plate, with a deep cleft in the middle. The latter group may for this reason and for the presence of vomerine teeth be separated as a distinct genus from Paludicola , namely as Pleurodema TSCHUDI. with the type Plcurodema Bibroaii TSCHUDI.*** A second species of this genus would be Pleurodema (Lystris) brachyops CoPE.t in which «xipliisternum an osseous style, with furcate cartilage disc», as stated by COPE. * In Paludicola gracilis BLGR. this branch absent and the lower edge of the dark band between the eye and the arm straigther. ** In Paludicola gracilis BLGR. mostly a well developed flat lumbar gland, covered above with a roundish black spot. *** The genus was called Pleurodema by TSCHUDI, but the species: Pleuroderma Bihronii (Classif. d. Batrachier, 1838, p. 84. 85). + Proc. Acad. Philad., 1868, p. 312.
