About 3 miles west of the South Mountain section 30 feet or more 
of dark-red shale outcrops in the Cold Spring road near the summit 
of the north face of the mountain. This shale probably belongs in 
the partly covered zones Nos. 28-30 of the above section and repre- 
sents apparently the Mauch Chunk formation. 
The peculiar calcareous bed, No. 26 of the section, agrees in its 
lithologic characters and horizon with a somewhat thicker bed of sili-;; 
ceous limestone in the Armenia Mountain and Tioga sections, viz, 
1458 B59, called the Armenia limestone lentil of the Oswayo forma- 
tion (see 127). 
FAUNA OF SOUTH MOUNTAIN SECTION. 
Careful search failed to discover any invertebrate fossils in the beds 
of this section. Fish remains, however, occur in abundance in at 
least two horizons. In zone 6, about 16 inches of the bed consist 
largely of a mass of the plates of Bothriolepls leidyi. Fragments of 
fish plates, probably B. leld/yi, occur also in zone 8, 425 feet above 
the base of the section. Above this no traces of animal remains were 
found. 
TOWANDA NARROWS SECTION. 
By E. M. Kindle. 
At the " Narrows," about 1 mile below Franklindale post-office, 
Towanda Creek has exposed a series of beds lying somewhat higher i 
than those which terminate the Gulf Brook section. The beds have a 
southerly dip which increases rapidly toward the north. The outcrops 
continue back to the limestone horizon of the Franklindale beds, along 
a small brook which joins Towanda Creek just above the " Narrows." 
This limestone of the Franklindale beds affords a good stratigraphic 
basis for the comparison of the two sections. Comparing the beds in 
the two sections, which lie above this horizon, it is seen that the- 
Towanda Narrows section extends more than 300 feet above the top of 
Gulf Brook section. The following section begins with the lowest 
outcrops near the point where the highway crosses a small brook, one- 
third of a mile north of the u Narrows."
