The Lower Cambrian fossils exhibited are specimens of a 
trilobite, Protolenus from Div. I 4, the lowest faunal zone of 
the St. John series. A considerable fauna was collected 
from this zone. It is now being studied by Mr. G. F. 
Matthew and will form the subject of a future communica- 
tion to the Academy. 
III. GRAPTOLITES OF THE GENUS DICTYONEMA, from the 
Upper Cambrian of St. John, N. B. Ductyonema, a funnel- 
shaped graptolite colony attached to the ocean bottom by a 
stem and roots. The smaller of the two large slabs holds three 
perfect specimens. The beds of papyraceous shale of Div. 
III c. Navy Island, St. John Harbor, are replete with these 
organisms. A future communication to the Academy by Mr. 
G. F. Matthew will contain new information regarding these 
and associated fossils. (See Exhibit II.) 
Exhibited by T. G. White (Department of Geology, Columbia 
College). 
IV. ORDOVICIAN FOSSILS, from the shores of Lake Champlain. 
Suite of specimens from the Ordovician series of the Lake 
Champlain valley. Exhibited by Theodore G. White, Ph.B. 
The preliminary paper on the field-work in two townships, 
Essex and Willsboro, was read before the Academy last May, 
and published in the Proceedings, vol. xiii., pp. 214-231. The 
study is now being continued to embrace the stratigraphy and 
fossils of the Ordovician rocks throughout the Champlain val- 
ley and their extension into Canada. The Terranes here repre- 
sented are: 
Utica: Trilobites and Graptolites. 
TRENTON: An abundant representation of Brachiopods, 
Trilobites, Gasteropods, Cephalopods, Lamelli- 
branchs, Corals, Crinoids, and plant remains. 
CHAZY: Several distinct sets of beds. Several large Gas- 
teropods (Maclurea) and Cephalopods; also Brachio- 
pods and Hydroid-Corals (Solenopora). 
CALCIFEROUS: Ophileta uniangulata and plant remains.
