species of brachiopods, twelve or thirteen of gastropods, nine 
corals and half a dozen pelecypods. Orthoceras, Rhynchodus, 
and Proétus are each represented by a single species; there are 
scattered crinoid joints and a few other species whose generic 
relations, even, have not yet been satisfactorily determined. 
Among the most abundant species are: Chonetes scitulus Hall, 
Stropheodonata nacrea Hall, Atrypa reticularis L. and a species of 
Spivifer with a marked depression in the fold of the brachial and 
a remarkably broad and strongly impressed muscular area in the 
pedicle valve. Iwo or three other species, both of Spzrifer and of 
Stropheodonta, are apparently represented. Stropheodonta demissa 
Conrad is probably one of the latter; another is a strongly 
arcuate form, with a thick shell and an almost smooth surface. 
Among other species which have been identified are Cyrtina 
hamiltonensis Hall (rare), Orthis impressa Hall (a single speci- 
men), Atrypa spinosa Hall, Productella spinulicosta Hall, and Cono- 
cardium cuneus Conrad (the three last fairly common). There 
is also a species of Afdyris; one of Weristella; a Cyclonema, near 
C. multilira Hall; two species of Loxonema of ordinary form; a 
tapering Zurritella-shaped shell, with both revolving and trans- 
verse striae, resembling but not identical with certain forms 
occurring in the Devonian of Manitoba and referred by Whit- 
eaves to the genus Loxonema; a Murchisonia, near M. turbinata 
Schlotheim; a Zvochonema-like shell with strongly angular and 
nodose revolving ridges; a Lellerophon, near B. pelops Hall or B. 
newberryt Meek; a Paracyclas and a Mytilarca. Among corals 
are a species of Streptelasma,; one of Zaphrentis; one of Acervu- 
faria and another of an allied genus; and a species of /avostites. 
The rock in which this fauna has been discovered is thought 
to constitute good material for road-making. A more extensive 
development of the quarry, which it is hoped will take place 
before long, will furnish opportunities for more satisfactory 
investigation of the fossils.
