Orthoceras, and Goniatites, with some Trilobites not fully identified, 

 and many species of Ccelenterata*. But as far as the known species 

 at present go, they do not bear out the view generally prevalent 

 among geologists, that these Looe-river beds are the representatives in 

 time of the Lower Devonian or Linton group of North Devon ; and the 

 fine Ichthyodorulites from this locality, in the collection of Mr. Pen- 

 gelly, have tjie obHque ridges appertaining to the Carboniferous typef. 

 The 42 species from the Looe district entered in Table III. do
