They were certainly proportionally larger and much more firmly knit than those of Dfudrerpctun. Further, the ribs were long and nuu;h curved, and imply a respiration of a higher character than that ot modern batrachians, and consequently a more highly vitalized muscular system. If to these structural points wc add the somewhat rounded skull, indicating a large brain, wc have before us a creature which, however puzzling in its affinities when anaioniically considered, is clearly not to be ranked as low in the scale of creation as modern tailed batrachians, or even as the frogs and toads. AVe must add to these also, as important points of dilVer- ence, the bony scales with which it was armed below, and the ornate apparatus of horny appendages with which it was chid above. These last, as described above, and illustrated in Fig. 144, show that this little animal was not a squalid, slimy dweller in mud, like Menohranchus and its allies, but rather a beautiful and sprightly tenant of the Coal formation thickets, vying in brilliancy, and perhaps in colouring, with the insects which it pursued and devoured. Remains of as many as eight or ten individuals have been obtained from three erect Sigillaricc, indicating that these creatures were quite abundant, as well as active and terrestrial in their mode of life. With respect to the affinities of this species, I think it is abundantly manifest that it presents no close relationship with any reptile hitherto discovered in the Carboniferous system, and that it presents characters partly allying it to the newts and other batrachians, and partly to the true reptiles.
