1879. On some Silurian and Devonian fossils from Manitoba and the valleys of the Nelson 
and Churchill rivers, J. F. Whiteaves, Geol. Sur. Can. 1879. Appendix 1, p. 45 C. 
This is a preliminary paper, giving provisional identifications of Silurian fossils from 
various localities, viz: Banks of the Red river, in the Parish of St. Andrews; Limestone 
rapids, 100 miles up the Nelson river: First Birch brook, Nelson river; Second and third 
limestone rapids of the Nelson river; Junction of the Little and Churchill rivers; Fort 
Churchill, (loose); Stony Mountain.

1879. Descriptions of new species of fossils from the Trenton limestone, by C. D. 
WaLcort; 29th report of the New York State Museum of Natural History; Albany, 1879; 
pp. 91-97. ‘Transmitted to the Legislature March 30, 1875.” 
The following species are noted from Wisconsin and Minnesota, all being new, and 
described without figures: 
Conchopeltis minnesotensis, four miles below Medford, Cannon river, Minn. Trenton limestone. 
Bathyurus longispinus, Trenton limestone, Plattsville, Wis. 
Asaphus romingeri, Trenton limestone, Quinby’s mill, Lafayette Co., Wis. 
Asaphus wisconsensis, Trenton limestone, Mineral Point and Plattsville, Wis. 
Descriptions of new species of fossils from the Chazy and Trenton limestones, by C. D. 
Wa corr; 31st annual report of the New York State Museum of Natural History; Albany, 
1879; pp. 68-71. ‘‘Transmitted to the Legislature April 17, 1878.” 
The following species are described, but not figured, from western localities: 
Ceraurus rarus, Trenton limestone, Beloit, Wis. 
Encrinurus trentonensis, Clifton, Grant Co., Wis., and two miles above Dunleith, III. 
Encrinurus varicostatus, Trenton limestone, Mineral Point, Beloit and north of Janesville, Wis. 
Dalmanites intermedius, Trenton limestone, two miles north of Dunleith, [ll.; Clifton, Grant Co., 
and Plattsville, Wis. 
Tllenus indeterminatus, Trenton limestone, Plattsville, Wis. 
Asaphus homalonotoides, Trenton limestone, two miles north of Dunleith, Ill. 
The Utica slate and related formations. Fossils of the Utica slate and Metamorphoses 
of Triarthrus becki. ©. D. Waucotrr. 1879, Albany. Printed in advance of vol. x, of 
the Transactions of the Albany Institute. June, 1879. 
The fossils described are from Oneida county, N.Y. In the discussion of the Utica 
slate the author reaches the conclusion that the Galena limestone is its northwestern 
representasive. The author gives a complete tabulation of the fossils occurring in the 
Utica slate, with references to the literature where described. This table also shows 
their extension into the Hudson River formation above and into the Trenton below. 
Another table shows the number of species that had been found respectively in the Utica 
slate and in the Galena, and the numerical range of the same into the Trenton and the 
Hudson River. This view of Mr. Walcott will be considered further in another place 
inasmuch as our studies do not tend toward the same result. *
