have been of the opinion that the hyomandibula might have fused with the pterygoid. 
That is to say the suspension of the mandibula would, if this be true, be hyostylic and

pension of the mandibula as an auto- 
stylic one, and at the same time em¬ 
phasizing the fact that the palato- 
quadrate was not coalesced with the 
neurocranium. 
That the bone in Wimania sinuosa 
interpreted by me as the metaptery¬ 
goid cannot belong to the hyoid arch, 
is shown by the following facts. As 
we have seen, it articulates with the 
basipterygoid process situated on the 
basisphenoid, while the hyomandibular 
always articulates with or is attached 
to the capsula auditiva. The ramus 
maxilaris and the ramus mandibularis 
trigemini seem either to have passed 
along the posterior border of the 
basipterygoid process and then across 
the dorsal margin of the basipterygoid 
bone or to have crossed the dorsal 
surface of the basipterygoid process 
obliquely in an antero-lateral direction 
- j and then to have passed down- 
wards and forwards along the 
lateral surface of the meta¬ 
pterygoid bone. The nervus 
facialis has had its exit from 
the neurocranium postero- 
medially of the metapterygoid, 
and the position of this bone 
in relation to the pterygoid 
bone is such that it cannot 
possibly be imagined to have 
been connected by ligaments 
with the ventral elements of the hyoid arch. In some Spitzbergen species described 
below I think I can also show with full certainty that the metapterygoid and the quadrate 
were connected with each other by a thick cartilage. 
It ought thus to be considered as pretty certain that the palatoquadrate of Coelacanthids 
articulated with the neurocranium in the posterior part of the orbitotemporal region at
