maxillary bones blend with the mid-nasal septum in some specimens

of Megalema asiatica, whilst in others they remain free from one 
another, separated by an inconsiderable interval. In Pogonorhynchus 
bidentatus and Tetragonops ramphastinus they completely blend across 
the middle line, without the nasal median septum persisting in 
front of the junction. So these two last-named species, and most 
probably all the species of the genera, are genuinely desmognathous. 
The point in which the truncated vomer of the Capitonide most 
differs from that of the order Passeres is that in the former the 
truncation occurs behind the line joining the posterior angles of the 
maxillo-palatines, whilst in the latter the truncation occurs some way 
in front of the same transverse line. The limbs of the forked vomer 
in the Capitonide run forward to meet.the posterior angles of the 
maxillo-palatines ; in the Passeres they continue, often in cartilage 
alone, to the nasal labyrinth. 
In Indicator the vomer is less ossified than in the Capitonide above Page 933. 
mentioned, and is smaller; the fork is slenderer and has longer limbs, 
which, however, quite typically join the well separated maxillo- 
palatines (which advance but slightly beyond the inner margins of the 
palatine bones) at their posterior angles.
