INVERTEBRATES. 411 



The specimen is not in a condition to shovr the head or feet ; yet we are 

 strongly inclined to believe from its form, and peculiar, regularly arranged 

 bundles of hairs, that it is a Caterpillar. If we are right in this suggestion, 

 its discovery is certainly an interesting one, as it would present an evidence of 

 the existence of Lepidopterons Insects, at a much earlier period in our world's 

 history than has hitherto been suspected. 



As this fossil will doubtless be met with in the Coal Measures at other locali- 

 ties, whether or not its relations to the mature Butterfly or Moth can ever 

 be positively established, it seems desirable for convenience of reference, that 

 it should receive a name ; although we are unable to point out any well defined 

 characters from the only specimen seen, by which it can be distinguished from 

 the larva of several existing types. That there is any probability, however, 

 of its belonging to any existing genus, will, we think, not be maintained by any 

 person familiar with the range of generic types of Insects in time . 



Locality and position : Same as last.
