ONISCID A. A441 
species belonging to this family are figured; but this 
writer carried the creation of species, not only of these 
animals, but also of the Acaride, to an undesirable ex- 
tent; every slight variation of colour being regarded as 
of specific value. It is very probable that when greater 
attention shall have been devoted to these creatures in 
this country, other species will have to be added to our 
native lists than are described in the following pages. 
This family is divisible into two sub-families— 
1. The Ligiine, having the flagellum of the outer 
antenne multiarticulate, and the terminal pair of caudal 
appendages with the basal jomts greatly elongated, and 
terminated by two long and slender subequal rami; 
consisting of the genera Ligia (sub-marine species), and 
Ligidiim, composed of a single European species, found 
in damp moss. 
2. The Oniscine, having the flagellum of the outer 
antennz not multiarticulate, and the terminal pair of 
pleopoda with the basal joints very short, and furnished 
with two short flattened unequal rami, of which the 
inner is sometimes nearly obsolete, comprising the 
remainder of the species.
