 bited an important difference from those of B. australis. In it they 

 number respectively 2, 5, 6, 3, 3, while Cuvier gives (Oss. Foss. 

 227. 23) 2, 5, 6, 5, 4."

M. van Bcneden regards the* character on which this genus is 

 established as merely a variation of Bahma australis (Osteog. Cet. 

 p. 35). 



The skeleton was sent from the Cape of Good Hope by Dr. Hor- 

 stock. It is described by Schlegel, Abhand. Gebiete der Zool. 1841, 

 p. 37 (Flower, P. Z. S. 1864).

 (which easily splits into strips), and a bifid first rib.
