1. On a New Species of JEdestus from the Uppek Carbon- 

 ifebotts of Yorkshire. By Abthub Smith Woodward, 

 LL.D., F.R.S., V.P.G.S. With a Geological Appendix by 

 John Pkingle, F.G.S. (Read June 28th, 1916.) 



[Plate I.] 



The remarkable Upper Palaeozoic fossil Edestus has already been 

 proved to represent a row of symphysial teeth of an Elasmobranch 

 fish, but it has hitherto been found only once in direct association 

 with portions of jaws. 1 A second specimen, still more instructive, 

 has now been obtained by the Geological Survey from the upper 

 part of the Millstone Grit at Brockholes, near Huddersfield, and 

 I am indebted to Dr. Aubrey Strahan and Dr. F. L. Kitchin for 

 the opportunity of studying it. The circumstances of its discovery 

 are described in the Appendix by Mr. John Pringle. 



The new fossil, shown of two-thirds the natural size in PI. I, 

 fig. 1, displays a single example of JEdestus, with a detached dental 

 crown and another fragment of the same form, near the tapering 

 ends of a symmetrical pair of cartilages (c) which evidently repre- 

 sent a jaw. Whether they are upper or lower is uncertain, on
