CAMBRIAN OF Mount STEPHEN, B.C.'

By J. F. Wuirnaves. 
ANOMALOCARIS. (Gen. nov.) 
Carapace and its appendages unknown or too obscurely 
indicated for their characters to be defined: body many 
jointed and consisting of not less than nine to thirteen seg- 
ments, exclusive of the caudal segment; ventral portion of 
each of the body segments bearing a pair of slender, nar- 
rowly elongated and acutely pointed, simple and probably 
branchial appendages, of the nature of uropods or foot gills: 
posterior terminal segment margined with three pairs of 
caudal spines, one terminal and the other two lateral,—the 
posterior pair of uropods represented in the wood-cut 
apparently belonging to a pre-caudal segment whose 
posterior boundary has been obliterated.
