4. Orthoceras bebryx var. cayuga (r). 
5. Parodiceras disco ideum (c).

The beds containing this Nunda (Buchiola speciosa) fauna are prob- 
ably 150 feet thick. They are followed by 100 feet or more of soft 
greenish clay shale in which no fossils were found. 
The following zones are exposed in the cuts along the railroad 
southeast of White Sulphur Springs. About 150 feet above the last 
zone the greenish shale, 1380 B2, contains the following species: 
Faunule of zone 2 of section 1380 B, near White Sulphur Springs, W. Va. 
[a, abundant; c, common; r, rare.] 
1. Orbiculoidea neglecta (c). I 3. Delthyris mesicostalis (r). 
2. Leiorhynehus laura (a). 
4. Ambocoelia gregaria (a). 
About 60 feet above the last zone is greenish shale containing the 
following species:

About 140 feet above 1380 B3 is a gray to greenish shale which 
contains the following fossils: 
alt is important to notice that the species described by Hall in the fourth volume of Paleontology 
of New York (1867, p. 110, pi. 19, figs. 1-5) under the name Strophodonta cayuta n. s., and afterwards 
described generally in literature under that name, was described by Conrad in 1842 (Jour. Acad. Nat. 
Sci., Philadelphia, viii, p. 257, pi. 14, fig. 10) under the name Strophomena mucronata, and referred to 
the proper fauna (Chemung) to which it belongs and cited from a typical Chemung locality, Chemung 
Narrows, in southern New York. The species described by Hall in 1867 under the name Strophodonta 
mucronata (see p. Ill, pi. 15, figs. 13, 14) and cited as the same as Conrad's species is actually dis- 
tinct specifically and at least subgenerically. It belongs to the subgenus Leptostrophia of Hall and 
Clarke, and was previously correctly figured, but not described, by Vanuxem in 1842 (Geol. New York 
Kept. Third Dist., 1842, p. 174, fig. 1) under Phillip's name Strophomena interstrialis. As Phillip's spe- 
cies is also subgenerically distinct from it, the specific name interstrialis is available in the combina- 
tion Leptostrophia interstrialis Vanuxem. Phillip's species would be Douvillina interstrialis. Stropheo- 
donta {Leptostrophia) interstrialis Vanuxem is abundant in the Ithaca formation, and, though it may 
occur in the Chemung, is there extremely rare. On the other hand, Stropheodonta {Douvillina) mucro- 
nata Conrad does not, so far as thorough examination has revealed, occur until the Chemung epoch, 
and is a diagnostic Chemung species.— H. S. W.
