In external form the body was very round but tapered very fast 

 behind the dorsal to the tail. The two last feet being scarcely one 

 quarter the circumference of the body ; the mouth was not pro- 

 longed into lips or snout like the ocean porpoise. The outline 

 arising from a somewhat prominent forehead rose gently to the back 

 fin, then fell suddenly to the tail which was set up like a duck's. 

 The lower line of belly, commencing from lower lip, slightly con- 

 cave, swelled rapidly into a convex line till beneath dorsal, then 

 sloped rapidly to tail. The whole appearance, though evidently 

 elastic towards its tail, was that of a firm inflexible body, which 

 did not give way to its own weight, or become flattened when out 

 of water, as the sharks often do. The line of mouth ran upwards 

 crossing the line of the axis of body at about an angle of 40°. If 

 produced it would run through the back fin. The under lip closed 

 into the upper ; the eye was small and near the angle of the mouth, 

 the external orifice of the ear a little behind the eye, was of the 

 size of a bristle ; the fore fin was very small, inflexible, of a long 

 oval, and though nearly immovable yet having a slight flexion at 

 the humeral joint, and this joint was outside the integuments ; the 

 back fin was a little higher than long, anterior edge slightly concave 

 at base, but well convexed at tip — the posterior edge well concaved. 

 In this instance I did not notice the small spines on the anterior 

 edge of fin, but as my attention was not called to it, and as after- 

 wards I examined eight or ten of both sexes and found them upon all 

 I must have overlooked them, and must conclude they are typical. 

 The spread of the tail which was horizontal and turned up, was one 

 foot ; the mammas were hid in two small folds on either side of a 

 deeper and larger fold, holding the vulva ; the male organs were 

 hid in a like fold ; the mammary glands, when opened, appeared to 

 be a plexus of vessels, turgid with red blood, and a thick white milk
