the fossil body. The single example of these worms which is not 

 closely coiled has the body partly flattened and partly com 

 pressed laterally so as to bring the setae into profile, but the 

 other specimens (three in number) are more or less closely coiled 

 and their structure, save the bristles, is not as distinctly set 

 forth. These all have a certain resemblance to lulus and other 

 myriapods and the fact of their occurrence in sands where com- 

 minuted remains of terrestrial vegetation have been freely ao 

 cumulated, at first suggested this as their probable character, 

 but the specimens do not on close examination reveal the 

 structures of that group. This second group of worms may be 

 designated as Palaeochaeta devonica. 



Geologic horizon and localities. All these bodies occur in the 

 sands, flags and shales which in the Naples (Ontario county) 

 section lie immediately above the layers which carry the last 

 rex>resentatives of the Intumescens fauna. These layers are 

 locally known as the Hatch sands and carry very few fossils, 

 Paropsonema cryptophyum, Orbiculoidea mag- 

 n i f i c a , a linguloid of peculiar aspect, Hydnoceras, with frag- 

 ments of Lepidodendron and other plant remains. AYitli one 

 exception all are from the village of Naples, Ontario co. and Italy 

 hill, 3 miles northeast in Yates county. A single example is from 

 soft olive shales a few feet below the horizon of the Grimes sand- 

 stone, Grimes gully, Naples.
