Lloydia ? strenuus, (Billings). 
Bathyurus strenuus , Billings, 1865. Palaeozoic Fossils of 
Canada, Vol. I, p. 204, fig. 188. 
This species is referred to Lloydia with considerable doubt. 
It looks more like a Bathyurus than do typical species of Lloydia , 
but has small eyes, and an elevated, wire-like rim. The speci- 
mens are from the boulder at St. Antoine de Tilly. 
Genus Leiostegium nov. 
( i leios , smooth; siege, covering.)
