We find from this that it is of a thicker form of body than the Balæmpteræ. Its greatest 

 thickness is a little behind the pectoral fins or about the middle of the body. The fore part of 

 body is but slightly tapering, and the head is obtuse in front. The body tapers considerably 

 backwards, and is of a conical form until somewhat before the caudal fin, where it is almost 

 square, in consequence of its having four longitudinal ridges— an upper one, a lower one, 

 and one on each side. The upper one of these is the largest,^ and extends backwards almost 

 over the middle of the entire caudal fin. The upper border of the head, seen from the side, has, 

 a little \\\ front of the angle of the mouth, a rather large obtuse prominence, on which the nasal 

 openings are situated. In front of this it is strongly curved downwards. The mouth is also 

 strongly arched in about the same direction as the upper margin of the head, with the strongest 

 curve in front. The lower side of the head is flat and but slightly convex. The lower jaw is 

 considerably wider than the upper one, and even longer, with lips about five or six feet high, 

 which surround the sides of the upper jaw and the baleen when the mouth is closed. The 

 margins of these lips descend somewhat obhquely to the point of the lower jaw, where at the 

 junction they are quite low. They are low also at the angles of the mouth, but in other parts 

 they are of almost equal height. There are a few small and scattered white hairs on the point 

 of both jaws. The eyes are very small and are immediately behind and a little above the angles 

 of the mouth. The blowers are two longitudinal openings 6"— 8" long. The orifices of the ears 

 are so small that Scoresby did not discover them until after the skin was removed. Fabricius 

 says that they are of the size of a quill. The head, when seen from below, seems wider and 

 more blunt than when seen from the sides, and the lower jaw has a shallow depression in front. 

 The navel is, according to the drawing given by Scoresby, somewhat behind the middle of the body, 

 and the vent is farther back, somewhat behind the beginning of the posterior third of the body. The 

 pectoral fins, the length of which is about f of the length of the body, are just behind the ante- 

 rior third of the same, and seem rather short, but are wide and obtuse. Their hinder edge is 

 rounded, and more convex than^the fore edge. There is a small hollow on this edge, behind their 

 short and almost blunt point. The caudal fin is very large, and its width sometimes exceeds 

 5 of the length of body. Its hinder edge is convex in the middle, and there is, as usual, a deep 

 notch in this convexity. It is said sometimes to reach a width of 26'. The long and rather 

 thick blades of baleen, which in the middle of the upper jaw sometimes reach a length of 15', 

 are not wide at the base, and decrease very gradually in width towards the point, retaining about 



^ It seems, therefore, here somewhat compressed, according to Scoresby's figure, because the height 

 is greater than the width.
