Dr. A. Smith Woodwael, F.R.S., V.P.G.S., exhibited speci- 

 mens of the problematical ichthyolite, Ccelorhynchus, 

 from an Eocene deposit in the Ombialla district (Southern Nigeria), 

 and discussed the nature of this fossil. Microscope-sections of the 

 well-preserved Nigerian specimens confirmed W. C. Williamson's 

 determination that Ccelorhynchus is an essentially dermal struc- 

 ture. A similar section of part of the rostrum of the teleostean 

 fish Blochius, from the Upper Eocene of Monte Bolca, near 

 Verona, showed an almost identical structure. The precise nature 

 of this rostrum remained to be determined, but there could be no 

 doubt that the so-called ' Ccelorhynchus ' is the corresponding 

 part, either of Blochius or of an allied genus.
