G4 ESCHRICHT AND REINHARDT 



aiul the intestines removed, so that tlie shape of the Uviiig animal is likely to be somewhat 

 different. 



Near the vent the bodj^ imperceptibty passes into the tail. The length of the latter 

 measm-ed to the notch between the lobes of the caiidal fin, was -^^ths of the total length. A 

 section through it is, just behind or close before the vent, of an oval form, but while tapering 

 towards the fin it is at the same time compressed so that it gets an obtuse keel both above 

 and beneath, which is still continued in the caudal fin Avhere it is gradually lost at some distance 

 from the notch between the lobes. 



The caudal fin (Plate I, fig. 6), had almost the form of a Turkish crescent, if we except 

 the roundish incision of the depth of about two inches between its two lobes. The distance 

 between the points of these lobes was in the newborn specimen four feet two inches, so that the 

 breadth of the caudal fin was four thirteenths of the length of the animal. 



The vent was situated in the newborn sucker four feet in front of the notch in the 

 caudal fin. It was, as is generally the case in the whales, angular with thick and wrinkled 

 edges, the point turned forwards, while behind it had a breadth of six lines. 



At a small distance before the vent (in the newborn animal two inches nine lines) we found 

 the opening of the pudendum of the female, in the shape of a longitudinal fissure five inches and 

 ten lines long, with thick edges. In the anterior end of the opening the clitoris was seen. 

 It was rather thick at its root, then very much compressed, almost flat. It was so unsymmetrically 

 attached to the vestibulum, by means of its two lateral parts that its point was turned very 

 much to the left side. Its length might be reckoned at about two inches. Close behind the 

 clitoris the outlet of the urethra was situated, at the foremost edge of which we found a conical 

 wart, about three lines long, which may probably serve as a valve. 



On either side of the pudendum of the female, and somewhat nearer its posterior than to 

 its anterior end, is a lengthened fissure (in the newborn whale about one inch long), at the 

 bottom of which the nipple is to be found. 



The umbilicus was, in the newborn female, two feet three inches in front of the pudendum 

 rather nearer to the foremost point of the head than to the incision of the caudal fin. In a 

 section through the cord the two umbilical arteries and the two veins Avere seen, and in the 

 middle the urachus. 



The fins or swimming paws are placed very Ioav and close to the back of the head ; in the 

 newborn individual only five inches behind the angle of the mouth, so that their anterior edge 

 begins almost immediately beneath the opening of the ear. Their length in this specimen was 

 two feet one inch, therefore one sixth or one seventh of that of the entire body ; their breadth 

 in the middle, where they are broadest, about half as much.'j Close to the root they are slightly 

 constricted ; their anterior edge is only slightly curved, their posterior edge more strongly so ; 

 their extremities are very obtuse. 



Of the most external, very thin, and horny layer of the epidermis no traces remained in any 



^ These measuremeuts, compared with those of Scoresby ('Ace.,' i, p. 464), will show that 

 the fins of the newborn Greenland whale are, comparatively speaking, somewhat longer, but 

 narrower than those of the older animals, in which their length is always under one seventh, but theu-^ 

 breadth nearly three fifths of the Avhole length. (Compare the description given afterwards of the 

 skeleton.)
