2 ANNALS OF SCOTTISH NATURAL HISTORY 



the epiphyses being ununited, the sternum remaining in 

 three pieces, and the teeth having been still covered by the 

 gum. The upper jaw is of course edentulous ; the teeth of 

 the lower jaw, three on each side, displayed in the prepared 

 skeleton, being placed near the symphysis. They vary from 

 -| to -?- of an inch in length, the anterior being the shortest : 

 calcification, though not complete, has extended considerably 

 below the margin of the crown. 



But the most noteworthy peculiarity of the skeleton is 

 the remarkable want of lateral symmetry displayed by the 

 pectoral limbs and by the anterior part of the sternum. The 

 left flipper is fully one inch longer than the right ; the former 

 measuring i 3^-, the latter i 2-^ inches in length. No difference 

 in size is observable in the scapulae or humeri of the two 

 limbs, but the radius and ulna are at once seen to be larger 

 on the left side. On the left flipper the 2nd digit has 8 

 ossifications, the 3rd six ; while on the right these members 

 are respectively 7 and 4. In the normal adult the number of 

 these ossifications are 10 in the 2nd, and 8 in the 3rd digit. 1 



The sternum consists of three pieces, of which the anterior 

 is very unsymmetrical, being much larger on the left than on 

 the right side of the mesial line. The left side of the second 

 piece has unfortunately been cut away ; the third piece is 

 symmetrical. This want of lateral symmetry in the limbs 

 constitutes the principal point of interest in this skeleton, and 

 I am not aware of any similar case having been recorded in any 

 of the Cetacea.
