SECOND APPENDIX TO 



Two papers by the second author which are currently in press (Sarjeant 

 1983a, b) , and may not be published until after this checklist has appeared, include 

 further revisions to the taxonomy of some of these species mentioned herein. Both 

 are restudies of European type material; the first deals with the Oligocene to 

 Miocene taxa described by Maier (1959) and the second with the Jurassic types of 

 Klement (i960). The imminent revisions are not cited here, to avoid priority 

 problems; but the Maier species concerned are marked with a single asterisk (*), 

 indicating that reference should also be made to Sarjeant (1983a), and the Kle- 

 ment species with a double asterisk (**), suggesting reference to Sarjeant (1983b).
