EXPLANATION OF THE PLATES. 



PLATE L 



All the figures in this Plate are taken from the young whale sent from Greenland, in brine, by 

 Major Easting. 



Fig. 



1. The newborn Greenland whale {Balæna mysticetus, L.), one thirteenth of the natural size. 



2. The head seen from above, same diminution. 



3. The blow-holes, represented half their natural size. 



4. The anterior part of the underlip, somewhat diminished, with the two groups of hair-knobs, 



out of which, however, the hairs themselves had already fallen when the specimen 

 was received. 



5. The muzzle, also somewhat diminished, with its hair-knobs. 



6. The tail, with the caudal fin, one thirteenth of its natural size. 



7. The anterior part of the cavity of the mouth, showing that the two baleen matrices do not 



meet anteriorly. Somewhat reduced from nature. 



PLATE U. 



1. The forty-seven and a half feet long Greenland whale skeleton, seen from the side, 

 forty-eight times diminished. (The three anterior caudal vertebrae, the carpus, and 

 the postei'ior extremities, are represented from the forty-four and a half feet long 

 skeleton ; the caudal vertebrae have been bi'ought somewhat nearer to one another 

 than in their fresh state by the drying up of the intervertebral cartilages ; the tail is, 

 therefore, on the whole, somewhat too short.) 

 In the cranium, the letters have the following significations : 



h. The left parietal. 

 /. ,, frontal. 



i. „ interma-xillary.
