Alou" the back runs a row of .short sliaq) spines, their points directed backwaids,"and the imder parts are smooth and of a dull brownish white. The length of an adult specimen is seven or eight feet. We now arrive at the Kays. The first flimily of these tishes is evidently intermediate between the sharks and the skates, and is in many respects a very interestimr and remarkable grouji of fishes. The common Saw-fish, so well known from the singular (leveloi)ineiit of the snout, is a good ex'amjjle of this family. It has a very wide range of locality, being found in almost all the warmer seas, and even m the cold regions near the pole. In the illustration, a view of the head and saw IS given m the foreground, and the general shape of the iish is shown in the partly submerged figure alxive. The snout of this Iish is greatly jirolonged, and llattened like a sword-blade. On either edge it bears a row of tooth-like , firmly iml)edded in the bone, few, short, and wide at the base of the lieak, but beeiimiiig larger and ,set closer together towards the point.
