Fig. 5. Maxillary bone of a fish in the Warwick Museum, from a quarry 1 mile N.W. 

 of Coventry. The left-hand end of the figure seems to be the anterior extremity. 

 The bone, which is here thickened and rounded, gradually becomes thin and flat 

 towards the other end. Much of the thinner portion is wanting, but the impres- 

 sion of the lower surface remains in the sandstone, as shown by the dark shade in 

 the figure. The specimen seems to have been considerably worn, and to have lost 

 several of the teeth, before it became imbedded in the sandstone.
