Miscellaneous. 1G7 have been identified, and from this arrive at the conclusion that they present the closest resemblance to the jaws of Annelids and of certain Gephyrea. They give a list of three simple and four compo-Bite forms of Conodonts described and figured by Pander, which they identify with Annelid jaws figured by Ehlers, finding an agreement between the fossil aud recent forms not only in external, but also in histological characters. In connexion with this comparison the authors call attention to the fact that in the Annelids there is in both jaws an alternation of teeth of a simple conical form with those resembling the so-called composite Conodonts — that is to say, those in which the base of the organ is widened and bears two or more small points on each side of the large central cone. The Gephyrean, Halicryptus spimdosus, which is very abundant in the Baltic, also possesses denticles remarkably resembling Conodonts both in form and structure. The authors conclude their paper as follows : — "As the result of our investigations, therefore, it appears that in their structure the Conodonts have nothing in common with the teeth, composed of dentine, of the Selachia or any other fishes, nor with the corneous teeth of the Cyelostomi, and that they cannot be interpreted as lingual denticles of Mollusca, hooks of Cephalopoda, or fractured points of Crustacea, but that they agree admirably both in form and structure with the buccal apparatus of Worms, and especially of Annelida aud Gephyrea. " Consequently not only those already recognized by Hinde as Annelid jaws, but all the Conctdonts, are calcified cuticular buccal or oesophageal denticles of Worms, consisting of parallel lamellae superimposed upon each other. From the great multiplicity of form we may conclude that the Conodonts are derived from numerous genera and species, and that consequently, in the Palaeozoic era, the shores of the sea were peopled with a great abundance of Worms of very different kinds." — Sitzuiif/sb. der k. bayr. Akad. der Wiss., Math.-pTiys. Classe, 188G, pp. 108-136, with 2 plates. Note on the Rejytiles and BatracTiians collected by Captain Em. Storms in the Taaganyllca Region. By M. L. Dollo. In this paper M. Dollo enumerates the species of Reptiles and Batrachia collected by Capt. E. Storms in the neighbourhood of Lake Tanganyika, and describes two new forms. The Batrachia recorded are liappia marmorata, Giinth., and Bufo regularis, Heuss. The known species of Reptiles are Agama atricollis, Smith, A. planiceps, Peters, Varanus niloticus, Linn., Euprepes varius. Pet., Chamceleon dilepis, Leach, G. gracilis, Hallowell, Typhlops Schlegelii, Bianconi, Boodon infernalis, Giinth., Bucephalus capensis, Smith, Philothamnus Smithi, Bocage, Psammophis sibilans, Jan, Rhamphiophis rostratus, Pet., Atractasp>is Bibronii, Smith, Causus rhombeatus, Licht., and Viper a arietans, Schleg. The new species are both snakes. The Colubrine Qrayia Griardi, Dollo, is distinguished from Qrayia silurophaga, Giinth., by having the anterior temporal single instead of double, three instead of two
