P. 5666. Imperfect rostrum, split longitudinally, showing the 
anterior portions of the premaxillie apposed to the slender 
ethmoidal region ; probably from Lower Chalk, Cuxton, 
Kent. On the left side the anterior part of the pre- 
maxilla is proved to be solid, 'while its flattened oral 
border, to which the bases of the two enlarged teeth still 
remain fixed, is flanked by a slight rim or outer wall. 
The hinder part of the bone, which is somewhat bent 
downwards upon the anterior part immediately behind the 
Becond enlarged tooth, consists only of the thin, deepened 
outer wall with the tooth-bearing border fixed on its innei 
face like a shelf; the fragment preserved bears two teeth 
of considerable size. The two enlarged teeth of the right 
premaxilla are entirely broken away, but immediately in 
front of the attachment of the second there are remains of 
two very small teeth on the outer margin. There ate also 
indications of the two posterior teeth already mentioned 
on the left. Harford ColL 
P- 5673. Hinder end of jaws of left side ; probably from Lower 
Chalk, Cuxton. The quadrate is shown, meeting the 
hyomandibular at its postero-superior angle but m 
contact with the almost reniform metapterygoid along its 
upper border. The hinder end of the premaxilla is im- 
perfect, but still retains two typical teeth and the base ot 
a third. The shape of tho hinder end of the mandible 
resembles that on the right side of the type specimen ; but 
the articulo-angular element is less exposed on the outir 
face than in the latter, where the dentary seems to have 
been partly flaked away. Harford Co

behind ; Chalk, Kent. One of the enlarged teeth is 
preserved, and there are remains of the small teeth both 
behind and in front. As on the right side of the type
