Haasr.— Notes on Skeleton of Epiodon nove zealandix. 441 
The prefrontals, like in the former skull, begin 6:50 inches from the point of the 
rostrum, forming at the beginning a ridge, which continues for about eleven inches, con- 
stituting the central portion of these bones, and only gradually disappearing. For the 
last five inches they have a concave form. The premaxillaries here approach each 
other as in the Port Lyttelton specimen, but stand always half an inch apart. Here the 
beginning of the septum narium rises to within the eighth of an inch of the surface of the 
premaxillaries, gradually getting thinner and turning obliquely to the left, resting against 
the left of these latter bones. 
The excavation in the septum narium is, however, much deeper and wider than in 
the first described skull, being three inches wide and two and a half inches deep. "There 
is also considerable difference in the teeth of the two skulls, as a comparison of these 
figures will testify. I add two drawings of the right tooth. Pl. XXIV., fig. 2. 
The tooth of this skull is 2:85 inches long and 0:61 inches broad. It is covered every- 
where with a rough cement, which forms, iege near the lower extremity, wart-like 
protuberances, taking near the root-end ridgy 
lt is consequently longer than the tooth s: pe Lyttelton Harbour specimen, and 
although the tenth of an inch thinner, is a little heavier, 198 grains 
A portion of the pterygoid has been cut away when taking out the skull. Otherwise 
it is in a fine state of preservation.
