HaLe—PIGMY SPERM WHALE IN SOUTH AUSTRALIA 543 
representing apparently the neural spines of the posterior cervicals. The height 
of the mass, about 115 mm., is subequal to the greatest width (atlas, 118 mm.). 
The foramina are as in the female referred to, 
The neural avch of the first thoracie vertebra is complete; it is very different 
in shape from that of the adult female described, the neural canal being two-thirds 
as wide again as deep (pl. xviii, ef. fig. 4 and 12) and differs also in that the 
ephiphyses are quite free. 
The first sternebra (text fig. 17) is broadly expanded at the front (where 
it is nearly one-third as wide again as long) and tapers to a broad stem; its 
auterior margin is sinuate, with a small median incision and there is only trace 
of a groove , on posterior half, indicating the fusion of the two component, parts. 
The second seginent of the sternum also consists of 4 single piece with a very feeble 
median gutter; it is four-fifths as long as the first and is widest anteriorly, where 
it is little more than half as broad as lone, being thus considerably more elongate 
than in either of the other specimens recorded, In the third sternebra the two 
bones are completely separated.
