In bangsi the braincase is deeper relative to the length of the skull as well as, of course, actually deeper.
The incisors are orthodont; the rostrum is short and the braincase is wide.
The same is true as regards the amount of projection from the braincase of the anterior margins of the tympanic bullae.
The tympanic bullae are less inflated and less protruded from the braincase.
The size and rigidity of the braincase and palate, and the extent and rigidity of their contact with the skull.
These dimensions indicate that the braincase reaches full size early.
The individual teeth are larger and the tympanic bullae wider and at their anterior ends are more projected from the braincase.
That part of the braincase immediately above posterior root of zygoma is more conspicuously inflated.
Skull: Large; braincase well inflated; zygomatic arches strong and slightly appressed to skull.
The braincase is nearly as broad as in the Bornean species, but the zygomatic width is distinctly less.
