separable from the neural arches throughout the abdominal 
region, a fow behind the head being excessively thickened, 
while those beyond are still comparatively stout and with 
a slight sigmoidal bond. There is an undigested fish 
between the ribs. Lewis Coll.

46509. Head with anterior abdominal region. A. bone which seems 
to be the premaxilla is relatively small, and apparently 
extends slightly beneath the anterior end of the maxilla. 
The right ramus of the mandible is shown to boar one 
large slender conical tooth at the symphysial end, and a 
similar though smaller tooth further back. The anterior 
suborbital cheek-plate is relatively largo and marked by 
radiating branches from the slime-canal which traverses 
it. Lewis Coll.

exposed from beneath and displays a relatively small gular
