194 DR. H. BURMEISTER ON A NEW WHALE.  [Feb. 14, 
the bodies are much stronger, from 6 to 8 inches in diameter. The 
three first dorsal vertebree have transverse processes more rounded, 
and directed forward. After the third they are more flat and broad, 
and directed transversely to the sides. After these fourteen vertebree 
follow twelve others with thinner transverse processes, rounded and 
sharp at the end, and with bodies of much larger diameter—from 
10 to 12 inches. Then follows a strong vertebra, the thirteenth, 
12 inches in diameter, with a smaller and shorter transverse process, 
which seems to me the first caudal ; but as the epiphysis is wanting, 
there is no attachment for the heemapophysis on its hinder end. In- 
deed its body is flattened on the under side, not carinated as the body 
of the antecedent; which also seems to me to prove that it is the 
first caudal. Of heemapophyses we have four in the Museum, of un- 
equal size, the first 5 inches high, the largest 8 inches, and 3 to 
4 inches broad between the laminz. 
“The ribs are not perfect as regards number, but the first seven 
or eight are preserved. I send you drawings of the upper and lower 
extremities of the first four (figs. 6, 7, 8, 9).

“The sternum is wanting, and of the os hyoideum we have only 
the corpus, of precisely the same form as that figured in Cuvier’s 
Oss. Foss. pl. 25. f. 14. 
“Of the pectoral fin we have only the scapula, of which I send 
you a drawing (fig. 10); both processes are well developed and some- 
what compressed. 
“The animal was found some leagues from Buenos Ayres, on the 
banks of the River Plata, where it came ashore some thirty years 
ago. It was brought to the gardens of Rosas, at Palermo, where the 
Licblalien was eahabited a long time, till, after the fall of the tyrant, 
it was transferred to the Museum. The parts now deficient were 
then lost.
