8 STUDIES OF TASMANIAN CETACEA, 



sixth lumbar has been reached, eventually ending, i7i ioto,. 

 at the ninth vertebra from the caudal extremity. The 

 manus is wider than that of such dolphinsi as G-lobicepha- 

 lus and Tursiops, and the longest finger only develops 

 sevem phalanges, instead of eighteen, as in the case of 

 Glohicephalus. The ossicles present are apparently the 

 following : — 



Proximal row — Scaphoid. Lunare. Cuneiform. 

 Distal row — Trapezoid. Magnum. Unciform. 



In each hand the cuneiform is closely attached by 

 immersed cartilage, to the ulna, and as the whale was im- 

 matrLre it might have ankylosed later in life had the ani- 

 mal continued to live.
