SUPPLEMENT TO VOL. I. PAKT I. 



(Issued with Fascicle II.) 



ADDITIONS AND CORRECTIONS. 

 By B. L. Robinson. 



During the last year and a half much has been written relating to the 

 orders treated in Fascicle I. To subject this newly published but already 

 copious matter to the careful critique which it merits, and to incorporate 

 any great part of it in the present issue would considerably delay the 

 appearance of Fascicle II. On this account it seems best merely to cor- 

 rect the evident errors in Fascicle I, which have come to the notice of 

 the editor, and to add only such supplementary matter as can be satis- 

 factorily presented without loss of time, judgment upon many of the 

 recently proposed species and varieties being necessarily deferred.
