E distinguished by Ducks as ”Micrognathes”, accordingly to the Filistatoide, 
= Seytodoide and Enyoide, of which the two last-named families have a se- 
+ 
' parate claw-joint on the legs, like the ZZersilioide. With the Citigrade this 
family seems to me to be far less nearly related. 
"Only one species of this remarkable family has, as far as I am 
aware, as yet been met with in Europe, viz. Hersilia oraniensis Luc., which 
“Smion has found in Spain, and of which he had the kindness: E send me 
a specimen (a young 5) under the name of ”Hersiliola oraniensis”. As this

we form for ita new genus, with the name proposed by Simon, Hersiliola, 
“and we define it thus:

pne ve Type: Hersiliola oraniensis (LUCAS). 
A In Hersilia caudata Sav. et AUD., the typical species for Hersilia, 
the claw-joint of the tarsus is as long the tarsus itself, the superior spin- 
ners extraordinarily long, 3-jointed, and the 3" pair of legs in an unusual 
. degree shorter ‘than the other legs; even the armature of teeth on the claws 
is quite different from that of Hersiliola oraniensis 1). Lucas has himself 
explained the properties that distinguish 7. oraniensis from the other known 
‘species of Hersilia; he formed for it a separate division of that genus, 
characterised by the shorter spinners and comparatively long 3" pair of 
legs, but considered these characteristics as not of sufficient importance to 
justify the formation of a new genus ?). 
; 7 In Hersiliola oraniensis the superior spinners are about double as 
long as the inferior, and consist of two cylindrical joints about twice as
