RAYMOND: NEW FOSSILS. 471 
described by Hall (1852, p. 337, pi. 78, fig. la-f), presumably 
from Conrad's type, is similar to the species here described, es- 
pecially in the ornamentation, but has a much wider cephalon 
and wider brim. 
Calymene cameraia as identified by Weller (1903, p. 25, pi. 22, 
fig. 22-25), from the Decker Ferry of New Jersey, is more like 
C. wigglesivorthi than C. camerata Conrad, in being narrow, with 
a narrow brim, but the anterior lateral glabellar lobes are faint 
or absent, and the palpebral lobe is remarkably close to the dor- 
sal furrows. I should not consider the figured specimens as 
belonging to either species. Calymene camerata has also been 
reported from the Helderberg of Maryland by Maynard (1913, 
p. 494, pi. 89, fig. 9). Only the pygidium is figured and there 
is no description. 
Calymene rugosa Shumard may be from the Devonian, but 
only the pygidium is known. 
C. wigglesivorthi most closely resembles some of the many 
varieties which pass under the name of Calymene hlumenbachi 
Brongniart, approaching closely such a form as that figured by 
Salter (1865, pi. 8, fig. 7), as showing the long narrow type of 
cephalon with long glabella. Our species differs from that chiefly 
in the much more delicate ornamentation. 
Wilhams (1914, pi. 21, figs. 2, 2a, 5) has reported Calymene 
hlumenbachi from the Pembroke formation (Upper Silurian) of 
southeastern Maine. The specimens are not described, but as 
figured, the cranidium is quite similar to that of C . wigglesivorthi, 
differing chiefly in having the anterior lateral glabellar lobes 
larger. The kind of ornamentation is not indicated. 
Horizon and locality. — The single cranidium is from the Chap- 
man sandstone at Edmunds Hill, Chapman Plantation, Aroos- 
took County, Maine. On the same fragment of rock are more 
or less imperfect specimens of Spirifer cymidis Clarke, 8. sparsa 
Clarke, an Eatonia, Leptaena, and some poorly preserved bry- 
ozoans.
