Zone 61 of Gulf Brook section (11+55 A). — Twenty-seven feet of thin- 
bedded sandstone with very few fossils extend from the last zone to 
the top of the first waterfall. 
Zone 62 of Gulf Brook section (11+55 A). — This zone, which lies at 
the top of the fall, contains Camarotoechia cf. eximia and Spirifer 
disjunctus. Both forms are common. 
Zone 63 of Gulf Brook section (11+55 A). — This zone includes 5 feet 
of cross-bedded purple limestone lying near the top of the fall. Cani- 
arotmchia cf. eximia is abundant and Spirifer disjunctus is common. 
Zones 64- to 68 of Gulf Brook section (11+55 A). — These zones contain 
comparatively few fossils. 
Zone 69 of Gulf Brook section (11+55 A). — Four feet of reddish lime- 
stone at the foot of the falls contain the following species: 
Faunule of zone 69 of Gulf Brook section ( 1455 A ) . 
[a, abundant; c, common; r, rare.] 
i. Camarotoechia cf. eximia (a). I 3. Spirifer disjunctus (c). 
2. Cryptonella cf. eudora (a). | 4. Modiomorpha sp. (r). 
The Cryptonella eudora noted here is a much larger variety than 
that occurring in the Ithaca fauna; otherwise the two appear to be 
identical. 
Zones 70 to 7°2 of Gulf Brook section (11+55 A). — No collections were 
made from these zones. Fossils are scarce in them. 
Zone 73 of Gulf Brook section (11+55 A). — Ten feet of reddish lime- 
stone near the lower end of the gorge contain the following fossils: 
Faunule of zone 73 of Gulf Brook section (1455 A) . 
1. Fistulipora sp. (rare). 
2. Camarotoechia cf. eximia (common). 
3. Cryptonella eudora var. (rare). 
4. Spirifer disjunctus (abundant). 
The specimens of aSj). disjunctus are large, squarish, slightly con- 
vex shells with a wide, shallow sinus and slightly elevated fold. 
Zones 71+ to 77 of Gulf Brook section (11+55 A). — These zones, which 
aggregate a thickness of 35 feet 6 inches, outcrop in a field a few rods 
east of the gorge. They contain at this point an abundant fish fauna, 
embracing the following species: 
Faunule of zones 74 to 77 of Gulf Brook section (1455 A) . 
1. Holonema rugosa. 
2. Bothriolepis minor. 
3. Holoptychius filosus. 
4. Coccosteus macromus. 
The fishes listed from this zone were collected by Mr. A. T. Lilley 
and identified and described by Cope. a The fish remains are most
