SUPPLEMENTARY APPENDIX. 



BY THE EDITORS. 



In order to render this work more readily complete and consultable for the student of 

 British fossils, the Editors have added the following catalogue of published British Trilobites. 

 It consists of the list of Trilobites, in alphabetical order, given by Mr. Morris in his valuable 

 Catalogue of British Fossils, with a concordance showing their names or the places where 

 they are referred to in this edition of Professor Burmeister's Monograph ; also a list of such 

 new Ti'ilobites as have been described by Mr. M'Coy since the publication of Mr. Morris's 

 Catalogue. Through the kindness of Mr. Salter they are enabled to add the names of the 

 new species described by him in Professor Sedgwick's forthcoming work on the ' Geology 

 of Wales and Westmoreland.' 



They have also appended some useful extracts from recently published foreign works 

 on Triloliites.
