On some portiona of it tliei'e are delicate transverse lines about a quarter of an inch ajjart, and apparently corresponding to those which on the newts and Menobranchus mark the bands of subcutaneous muscles. The bony scales of the abdomen have dis- appeared, except a few scattered in the matrix. But the most remarkable dermal appendages are those triangular lappets or frills of which I have in previous papers described detached examples, and have compared them with the gular and cervical lappets and frills of iguanas, geckos, and Draco; and which also suggest analogies with the processes that support the gills in perennibranchiate batrachians, and with the lateral folds of the skin in Menopoma. These append- ages are flat and of appreciable thickness, about half an inch in length, and an eighth of an inch in breadth, terminating in an edge or obtuse flat point, which seems to have been horny, while the appendage itself must have been flexible. Tl'.cy are marked with small scaly oval areoles or projections, placed somewhat in rows, and each with a minute puncture in its centre. The markings o'^ both sides are similar. These appendages are arranged in series along what appears to be the skin of a fore leg, and also in groups apparently on the an- terior part of the body, perhaps the neck or shoulder. They appear to be closely connected with a series of much smaller angular points which extend along the edge of the skin near the supposed leg, and probably fringe the sides of the abdomen. The evidence that this integument belongs to Dendrerpclon Acadicmnn is derived from the presence in its anterior part of skull-bone
