The preceding arrangement is a modification of that proposed 
by myself in the Jbis (1874, p. 406). The principal altera- 
tions are adding the families Panuridz and Sittide in series 
A, commencing series B with Diceide; bringing Vireonide 
next to the allied American family Mniotiltide; and placing 
Motacillide in series C next to Alaudidee. At the suggestion of 
Professor Newton I place Menuridz and Atrichide apart from 
the other Passeres, as they both possess striking peculiarities of 
anatomical structure. 
The heterogeneous families constituting the order Picariz may 
be conveniently arranged as follows: 
51. Picidee Woodpeckers.
