world, but especially abound in the antarctic half 

 of the 



Kogia breviceps of de Blainville,* probably the 

 same as Euphysetes macleayi, Krefft, has 13 pairs of 

 ribs. Teeth confined to lower jaw, 14 or 15 on each 

 side ; not long. 



There is a complete skeleton of this whale at the 

 British Museum. The vertebral formula is C. 7 ; 

 D. 13; L. 9; Ca. 25. The first rib articulates with 

 the last cervical vertebra and the first dorsal. There 

 are seven pairs of ribs which have both capitulum 

 and tuberculum. The capitulum, it may be remarked, 

 is not situated between two adjacent centra, but is 

 entirely confined to the vertebra lying in front of that 

 which bears the tuberculum. I found four ribs to 

 join the sternum. The sternum is composed of three 

 pieces, not divided at all longitudinally. The first 

 sternal rib articulates with the expanded front of the 

 manubrium, which is rather cross-shaped, the two arms 

 beino- anterior. The second rib is attached between 



o 



the first and second pieces of the sternum, the third 

 between this and the next, while the last of the 

 sternal ribs articulates at the end of the terminal 

 piece of the sternum. 



The scapula is not so high as is that of Physeter, 

 but more fan-shaped as in the dolphins. It is not 

 concave externally ; it is practically flat. The number 

 of phalanges is as follows: I, 2. II, 8. Ill, 8. IV, 8.
