P.611. The type specimen figured by Dixon, op.cit.\ probably 
from the Lower Chalk, Durham, Kent. The premaxilla 
is broken at its anterior end, but displays the teeth and 
finely tuberculated border throughout the greater part of 
its length. The fragmentary scales exhibit the delicate 
striation. Egerton Coll. 
49737. Pragmentary remains of a small fish wanting the greater 
part of the head ; Lower (?) Chalk, Shalford, near Guild¬ 
ford. The pectoral, pelvic, anterior dorsal, and caudal 
fins are shown, and some of the caudal vertebrae are 
exposed. One scale behind the upper end of the pectoral 
arch is strongly marked by radiating furrows, evidently in 
connection with a sensory canal. Capron Coll.
