of the hill. For the upper members ( FlalystropJiia zone) the 
exposures along" the road (not the toll road) over the hill back 
of Vevay were used. This part of the section in.cludes fifty or 
more feet (zones a to h) above zone 86 of the main section.* 
Section- in ascending order. 
No. I. The first division. 100 feet thick, contains no exposed rock. 
No. 2. Very soft blue shale at mouth of ravine. No fossils, 6 feet. 
No. 3. Dark blue limestone containing Dalinanella multisccta Meek 
and Plectambonitcs scriceus Sowerby, in fair abundance. The 
limits of this exposure are very small, 6 inches. 
No. 4. Shale, 4^ feet. There is very little variation in the character 
of the shale beds throughout the section. 
No. 5. Limestone of the same character as number 3, 10 inches. The 
following fossils were collected from this layer: 
1. Cocloclcnia alternatiivi (James). 
2. Callopora onealli-sigillaroides (Nicholson). 
Very small form. 
3. Bytlwpora ardipora (Nicholson). 
4. Dalinanella mnltisecta (Meek). 
No. 6. Shale, 4 feet. 
No. 7. Limestone mottled with argillaceous spots. 5 inches. 
1. Batostouia implicatum (Nicholson). 
2. Pcronopora vera, t 
3. Dalinanella multisccta (Meek). 
No. 8. Shale, i foot. 
No. g. Thin layers of fine-grained, compact limestone, i foot. 
1. Callopora onealli-sigillaroides (Nicholson) (aa). 
2. Batostoma implicatuin (Nicholson) (c)§. 
3. Stictoporella sp. 
4. Ostracod indt. 
5. Cyrtolites cf. inornatus (Hall). 
6. Dalinanella multisccta (Meek) . 
No. 10. Shale with occasional thin uneven layers of limestone, 2 feet 
3 inches. 
No. II. Limestone mottled with argillaceous material, 3 inches. 
1. Callopora onealli-sigillaroides (Nicholson). 
2. Callopora sp. probably nodulosa (Nicholson). 
3. Batostoma implicatum (Nicholson). 
4. Peronopora vera. 
*The main section is section 1.3SA of the paiDer referred to aliove, and the 
upper zones la to h) constitute the upper portion of section 1.38B of the same 
IJaper. 
•f-A fragment lalieled P. vera by .Mr. Tllricli, in the Peabody Museum of Yale 
University, has been sectioned by the writer; and iilthough the worn condition 
of the specimen made it impossible to get a tangental section very near the 
surface yet there is little question of the specific identity of the Vevay speci- 
mens and the P. vera of Mr. Ulrich. 
§C — Common; a— atiund nnt; aa — very abundant; aaa — so abundant as to 
fill the rock; r — rare; rr — a single specitnen.
