WIL kin?le AND ] BUCHIOLA 3PECIOSA FAUNA. 53 
The black shale at Hot Springs, Va., contains the following species: 
Faunule of black shale of Hot Springs, Vet, 
1. Orbiculoidea doria. I 3. Anoplotheca cf. acutiplicata. 
2. Chonetes cf. coronatus. | 4. Styliola fissurella. 
This follows the hard cherty sandstones which stratigraphically 
represent the Oriskany. 
The section at Covington presents 15 feet of gray shale between the 
top of the sandstone (Oriskany) and the black shale (1382 B4). The 
black shale (1382 B4 and B5) contains the following species: 
Faunule of black shale at Covington, Va. 
[a, abundant; c, common.] 
1. Orbiculoidea lodiensis var. media. 
2. Orthothetes chemungensis var. arcto- 
striatus. 
3. Leiorhynchus limitare (a). 
4. Nucleospira concinna. 
5. Anoplotheca acutiplicata (c). 
6. Clinopistha antiqua. 
7. Buchiola speciosa (a). 
8. Nucula corbuliformis. 
9. N. cf. lirata. 
10. Nuculites triqueter. 
11. Leptodesma sociale. 
12. Actinopteria epsilon. 
13. Styliola fissurella. 
14. Tentaculites gracilistriatus. 
15. Coleolus tenuicinctus. 
16. Hyolithes aclis. 
17. Agoniatites vanuxemi. 
This fauna presents a combination of species not generally found in 
the New York formations, where the Marcellus, Genesee, and Nunda 
formations carry fairly distinct faunas. The dominant characteristics 
of the fauna are its Pteropods and Buchiola speciosa. Although it 
carries Leiorhynchus limitare in abundance, Buchiola speciosa is also 
abundant. 
There are a few other zones holding evidently the same fauna, which 
lie higher up in the black shales of the more northern sections. 1 
will select these on the basis of presence of Buchiola speciosa, either 
common or abundant. (See the chart, p. 5.) 
1380 Bl adds the following species to the list above: 
1. Paracardium doris. I 3. Orthoceras bebryx var. cayuga. 
2. Palseoneilo brevis. | 4. Parodiceras discoideum. 
1380 Dl adds Plethospira socialis and an unidentified Loxonema. 
1380 El adds nothing. 
1382 Dl adds Pterochsenia fragile and Goniatites. 
1383 A4 adds Chonetes setigerus. 
1383 A6 adds the following species: 
A small Zaphrentis. 
Leiorhynchus cf. laura. 
Amboccelia umbonata. 
Coleolus sp. 
Parodiceras discoideum. 
1383 A8 adds Palaeoneilo constricta and Coleolus acicula.
