TRILOBITES IN VICTORIA MEMORIAL MUSEUM

of which the type is lost, but which was probably a Lichad, he 
says there is another Bro7at>us present (afterward described by 
Billings as B. pompilius ) and adds: “The head of another 
trilobite armed with spines occurs.” 
A second specimen was collected in 1862 by Robert Bell at 
the Gros Morbe, in the same region. These specimens are of 
interest as showing the possible path of the migration of this 
species. The recent discovery by Mr. R. Harvie, of the Geo- 
logical Survey, of a pygidium of Bronteus pompilius and a cra- 
nidium of a Ceratocephala like C. goniata , in dark Silurian shales 
at Knowlton Landing, Lake Memphremagog, Que., furnishes, 
perhaps, another link in the route of migration.
