Carboniferous Rocks; but I am not yet sure that it ought to bear Phillips’s name 
in contradistinction to them. 
I see no difference between my specimen and Ch. Manitobensis, Whiteaves ; 
neither of them shows signs of any spines on the surface of the valves. Whiteaves 
regards his species as a variety of the Silurian C. striatellus, Dalman, sp.,' which 
is, however, a wider shell than ours. 
Ch. setiger, Hall,” and Ch. Logan, Norwood and Pratten,> are similarly 
marked, but have fewer rays.

pl. i, figs. 28, 23 a. 
Localities—From Lummaton there are four specimens in my Collection, and 
two, apparently from the same locality, in the Torquay Museum. 
Remarks.—I have nothing new to add about this species. 
It seems to differ from Chonetes minutus, Goldfuss, MS.,* in being more 
angular and in having a stronger concentric ornamentation.

Locality.—There are seven specimens from Lummaton in my Collection. 
Remarks.—These shells appear to agree accurately with Phillips’s figure of 
L. convoluta, but Iam by no means certain that they are anything more than the 
lower valves of the species described as Ch. Phillipsu by Davidson. They differ 
from it in having a less prominent beak, which does not overhang the hinge-margin, 
in their shape being more triangular, and in there being little or no sign of the 
beautiful transverse ornamentation seen in that species. My specimens are not, 
however, in a sufficiently good state of preservation to settle the point. If they 
are identical, the question still remains whether Phillips’s Croyde Bay fossils are
