"The symphysis is short and its peduncle Hat and square, separated from the cnrved arch by a deep semicircular emargiuation. The teeth are also stronger and stouter tliiin in Carpiodea and IchthyobiiH, as is also the case in Buhalichihys, and they are grad- ually increasing in size, and relative thickness from the upper part of the arch to the symphysis, but they are much fewer and farther apart than in the latter genus. Their iuner edge is triusverse, rather blunt, thoagh the middle ridgo is somewhat project- ing; the lower teeth are so shai)ed that their inner angle is liardly higher than the outer, while in the middle and upper teetli it is gradually more projecting, aiul from the middle of the arch upwards forms a prominent point aiched outwards. "The scales are considerably longer than high, winh a rather prominent posterior mar- gin; numerous radiating furrows upon the anterior and pcstcrior fields, some across tilt' lateral lields; the concentric ridges of the posterior liclJ are not only broader than those of the other fields, but instead of running parallel to the margin of the scales they are curved in concentric golhic arches between each two radiatin/t furrows. Heckel mentions this genus nnder the name of Ilhytidoslomm, but Rafinesque's name Cjickptua has the priority. Propt Jy it ought to bo called Lrplocijvhis, according to its ttyuiology, (see my Nomenclator Zo,)logicus; Index Universalis, p. lU'J,) but under thin t'urm nobody would recognise it as Kaiinesque's name.
