must be looked for in the still higher strata." The last deposits 
considered were correlated with the Chemung formation by the 
Pennsylvania survey in the upper portion of which they reported 
the characteristic Chemung species Spirifer disjunctus. From the 
lowest reported horizon of this species Dr. Kindle carefully searched 
every remaining foot of the so-called Chemung deposits without find- 
ing a single specimen of Spirifer disjunctus. This is in perfect 
harmony with the writer's experience in northeastern Pennsylvania 
where he failed to find this species which was reported in rocks of 
so-called Chemung age.* This detailed work of Kindle and Wil- 
liams confirms the writer's correlation in 1894 of the so-called Che- 
mung of northeastern Pennsylvania with the Paracyclas lirata fauna 
of the Portage of eastern New Yorkf which later he demonstrated 
belonged in the Ithaca formations It is interesting, however, to re- 
member that farther to the southwest in western Maryland the 
higher Devonian faunas contain numerous specimens of Spirifer dis- 
junctus associated with some of the other species which professor 
Williams lists as diagnostic of the Chemung. C. S. P.
