within the purpose of the Zool. Rec. to analyse minutely all the points in 
a monograph such as this, nor could such an analysis serve any useful 
purpose. A special feature is that the species of various genera are, to a 
certain extent, grouped iu accordance with the families of their bird-hosts, 
and showing that such a scheme of classification is, to a large extent, 
natural. Elaborate tabular diagnoses are given for Goniodes (pp. 20-22 $ , 
pp. 23 & 24 $ ), Gonioctes (pp. 68-70), Lipurus (which is divided into a 
number of groups, pp. 107 & 108, each of which is tabulated separately), 
Trichodectes (pp. 203-205). More than 40 already known species are 
redescribed, and the greater part figured.
