PART I CHAZYAN AND RELATED BRACHIOPODS—COOPER yA 
The Kauffman is thought to correlate with the Centre Hall member of the 
Nealmont formation. The following brachiopods were identified by Craig (1949, 
pp. 736, 737) : 
Dinorthis sp. cf. D. pectinella (Conrad) 
Doleroides sp. cf. D. pervetus (Conrad) 
Glyptorthis sp. cf. G. bellarugosa (Conrad) 
Leptaena sp. cf. L. charlottae Winchell and Schuchert = Limbimurina 
Lingula sp. 
Sowerbyella sp. ci. S. punctostriata (Mather) 
Strophomena 2 sp. 
Zygospira recurvirostris (Hall) 
Lantz Mills facies of Edinburg formation.—This name is applied by 
Cooper and Cooper (1946, p. 78) to the cobbly to nodular, buff-weathering lime- 
stone well developed near Lantz Mills about 4.6 miles N. 69° W. of Edinburg, 
Va. As a facies this type of lithology appears at various levels in the Edinburg 
formation. But on the west side of the Massanutten syncline and western belts 
it is best developed in the lower part of the formation where it comprises the 
Echinosphaerites-Cyrtonotella and Nidulites zones. On the east side of the Mas- 
sanutten syncline this facies alternates with the black shale and limestone of the 
Liberty Hall facies. The two fossil zones of the Edinburg formation mentioned 
above roughly correspond to the Shippensburg formation of Craig (1949) and 
are the Virginia equivalent of that formation. 
Brachiopods taken from the Echinosphaerites-Cyrtonotella zone of the Edin- 
burg formation are listed under this heading under the Edinburg formation. 
Correlation of lower Lantz Mills facies—The correlation of this part of the 
Lantz Mills facies of the Edinburg formation is with the interval from the Effna- 
Arline to the lower part of the Benbolt. Effna-Arline affinities appear in the 
presence of Ptychoglyptus, Christiama, Scaphorthis, Glyptambonites, and Cyrto- 
notella. Dinorthis transversa is a link to the Benbolt. 
Brachiopods from the Nidulites zone are listed under that heading under Edin- 
burg formation. 
Correlation of upper Lantz Mills facies —This portion of the Edinburg under- 
lies the St. Luke member which is correlated with the Witten and the Rockland 
formation. The part of the Edinburg with Nidulites bridges a long time interval. 
The fauna, too, is somewhat transitional in having the last remnants of the Ben- 
bolt (Dinorthis transversa) near the base and elements of the Wardell suite such 
as Strophomena in the upper part. 
Lemont member of Carlim formation.—This member was named by Butts 
(1918, p. 526) for limestone exposed in the railroad cut a short distance south 
of Lemont. At this place a species of Maclurites is fairly common and was con- 
fused by Butts with M. “magnus” Leseuer of the Chazy group. Butts thus re- 
garded his Lemont as a part of the Chazy and identified his member elsewhere 
in Pennsylvania where the rock was shaly and had M. “magnus.” The type sec- 
tion of the Lemont is actually at the top of the limestone sequence now called 
Nealmont (Kay, 1944, p. 97). Butts’ use of the name Lemont was generally
