a part of the shell where the diameter (allowing for crushing) is about 
15 mm., is 6 in the length of 8 mm. The characters of the external 
surface of the shell in our specimen were derived from a wax squeeze of 
an external mould in slate. 
The British species has been recorded from the Lower Ludlows, the 
Aymestry Limestone, and the Upper Ludlows, of Shropshire, Hereford¬ 
shire, and Westmoreland, respectively.

Track, Wood's Point.

Two fragments of a comparatively coarse-ribbed Ceratiocaris -carapace 
occur on specimen Xo. 380. The nature of the surface ornament, which 
also bears a faint oblique cross striation, points to a form like that of the 
above species, from the Lower Ludlows of Ludlow and Dudlev 
Occurrence .—North Boundary, Thomson River (31onograptus dubius 
beds).
