and the ectopteiygoid is shown to bear an insignificant 
narrow band of minute tubercular teeth extending a little 
distance obliquely upwards and forwards from the hinder 
end of its dentigerous border. The articulo-angular 
element, shown from the outer aspect on the left side and 
partly from the inner aspect on the right side, is proved to 
have been about three times as long as its maximum 
depth ; and the tubercles on its inwardly flexed lower 
margin are arranged along longitudinal, slightly radiating 
ridges. Remains of the operculum of both sides, exposed 
from the inner aspect, exhibit the usual median hori- 
zontally-directed ridge.

X species about as large as the type, known only by fragmentary 
specimens. Mandible closely resembling that of E. lewesiensis in 
form, proportions, and ornamentation. Palatine bone short and 
stout, the ethmoid articulation extending to its anterior end, where 
the long and slender tooth is directed downwards at right-angles to 
its long axis. Teeth slender, much compressed, and some delicately 
striated.

9249. Type specimen, comprising the imperfect mandible, left 
palato-pterygoid arcade, part of the right ectopterygoid, 
and other associated remains ; English Chalk. Both 
mandibular rami are much fractured, but that of tho 
left side (PI. XI. fig. 4) shows distinct remains of 
the characteristic ridged ornamentation, while that of the 
right side (fig. 4 a) exhibits the narrow symphysis with the 
irregular prominences. The long, straight, and slender 
front tooth is also best preserved on the right side. The
