The highly bituminous dolomites of Kokomo, Ind., have afforded a species of Eusarcus which was described by Claypole first as  then as. The peculiar character of this rock makes an unfavorable matrix and Claypole was successful only in outlining the body and legs of his species but careful treatment of a series of these specimens has made it possible to elucidate in some measure the essential structures of the creature. The type specimen has not been located by us (cited as belonging to Mr Newlin of Kokomo), but we have before us several specimens brought together by the late Professor James Hall and now belonging to the museum of the University of Chicago, one of which agrees so closely with the figure of the type as to suggest its identity with the latter. Another specimen [ pl. 39] in the same collection, both sides of which have been preserved, excels the type in the distinctiveness of several important features.

Besides these specimens we have two large individuals (one from the Hall collection, the other in the State museum) which correspond in size to Claypole's. This species was erected by Claypole for a specimen received from Mr Charles Smith of Akron, O.
