In the present state of our knowledge T consider it impossible t6 

 divide the birds hitherto referred or allied to the typical Timeliidce 

 into well-defined or definable subfamilies or groups. Hence the 

 views on their systematic arrangement are of necessity subject to 

 frequent changes ; and my own, with those of the author of the 

 fifth volume of the present ' Catalogue,' have consequently under- 

 gone considerable modifications since the commencement of the 

 printing of the previous volume. I have been obliged to depart 

 from the scheme of classification there proposed ; and I have found 

 besides, after a more lengthened study of these birds, that the family, 

 as at present constituted, contains many forms which are not real 

 Timeliidce, 



Under these circumstances the best plan seemed to me to be to 

 arrange the remaining forms under groups of one subfamily Time- 

 liime, viz. Thamnobiie, Bradijpttri, Eremomdce, Cisticohe, Chumcece, 

 Henicuri, Crateropi, Tiinelice, Liotrichcs, and Accentores.
