The transverse apophyses are as broad as the body of the ver- 

 tebra, and the latter is oblong, half as broad again as high. 



The lateral processes of the cervical vertebrae are much longer 

 than the width of the body of the vertebrae ; the lateral process 

 of the second cervical has a small, nearly central perforation, and 

 this perforation gradually becomes larger on each succeeding 

 vertebra, until it nearly occupies the whole disk of the lateral 

 process in the sixth ; the seventh being only formed with a nar- 

 row elongated process from the upper edge, the lower process 

 being reduced into the form of a small tubercle. 



Vertebrae 54 : viz. 7 cervical, 13 dorsal, 17 lumbar and 17 cau- 

 dal. The ribs are simple. 



The lumbar vertebrae are thick and large ; both these charac- 

 ters must render this Finner much more powerful and active in 

 the water than any of its allies. The lower jaw is 17 feet long; 

 the blade-bone 32 inches by 51. The upper arm-bone 20 inches 

 long by 10| wide ; the lower arm -bone 31 inches long. The chest- 

 bone is 28 inches wide and 18 inches long. 



The lumbar vertebrae are 1 1 inches long and 14 inches wide : 

 the first rib 59 inches long and 10 inches wide at the sternal 

 end. 



The specimen was found floating on the sea in a decomposed 

 state, on the 2nd of October 1831, in Plymouth Sound, and is 

 said to have been 102 feet long and 75 feet in circumference ; 

 but most likely the abdominal cavity was distended by the inter- 

 nal decomposition. 



It formerly travelled the country, curiously mounted in three 

 caravans, the first containing the head, the second the thorax,
