82 ROY L. MOODIE 
AMPHIBAMUS GRANDICEPS Cope 
(Fig. 24) 
This well-known species from the Mazon Creek deposits is restored 
herewith. The restoration is based on a specimen, nearly complete, 
in the collection of Mr. L. E. Daniels of LaPorte, Ind., and on the 
drawings of Cope. 
In conclusion I wish to express my hearty appreciation to Drs. S. W. 
Williston and Stuart Weller for the interest they have taken in my 
work and for the help I have received from them.
