ON THE DERMAL ARMOUR OF CROCODILUS HASTINGSIAZ 169 
armour of the last-named Crocodilian. As I have shown, in fact 
(doc, ctt.), no true Crocodile or Gavial possesses articulated scutes or 
ventral scutes. 
The teeth are more numerous in Alligators than in true Crocodiles, 
and, as the dental formula of C. Hastingsi@ is ==", we might regard 
its dentition as another approximation to the Adigatoride. But 
the value of this character is greatly diminished when we reflect that 
the teeth of Alligators are either equal in number in both jaws, or 
preponderate in the lower jaw; while the Croc. Hastingsie@ retains 
that preponderance of teeth in the upper jaw which is observed in 
true Crocodiles and Gavials. 
I may remark that a very fine skull of Crocodtlus Hastingst@, for 
the opportunity of examining which I am indebted to Mr. S. Laing, 
M.P., F.G.S., coincides in all its characters with the typical specimen 
of C. Hastingste in the British Museum. The roof of the canine pit 
is, however, somewhat widened.
