other very complex. The simple branch bifurcates, leading to 
the families Enyoidce and Scytodoidce ; from the latter spring the 
TlieridioidcBj and from these again the Epeiroidoi. The direct line 
of the second branch forms the family FUistatoidae ) but the 
families Urocteoidce and Omanoidoi ( = (Ecobiid(e, Blackw.) are 
supposed to be given off from this branch before the discrimi- 
nation of the Filistatoidce. From the latter springs a branch 
which gives off the Dysderoidce close to its origin, and leads up 
directly, after a longish interval, to the Theraphosoidce. { = My~ 
galidcB) ; and from these the Catadysoidoi (founded for Ca- 
tadysaSf Hentz) spring on one side, pointing towards tlie Tho- 
misoid(e, and the Liphistioid (2 (founded for the genus Liphistius, 
Schibdte) on the other, pointing in the direction of ih^Phrynoidce. 
Another branch, originating from the Filistatoidce , bifurcates 
near its base into the Hersilioidce and Drassoidce ; from the latter 
spring directly the Agalenoidce^ ThomisoidcBj and Lycosoidce, and 
from the last the Oxyopoidce^ pointing towards the Saltigrade 
group. The Saltigradce likewise spring from the Drassoidce \ 
their direct line terminates in the Myrmecioidce, and gives oflP the 
Attoidce ; another branch is formed by a new family, Othiotlio- 
poidce (founded by the author for the reception of M^Lcay^s 
genus Othiothops) ; a third branch bifurcates and bears the 
families Dinopoidee and Eresoidee, 
These 22 families are placed by the author in his suborders as 
follows: — I. OiiBiTELARiiE : 1. Epeiroidee II. Retitelarias :

Canestrini and Pavesi (Atti Soc. Ital. Sci. Nat. xi.) publish 
a catalogue of the known Italian species of this order (/. c. 
pp. 759-829), to which they append some general considerations 
(pp. 830-844), chiefly relating to the numerical proportions of 
the families and genera, and of the Italian to other European 
faunas. The number of species recorded by them in the dif- 
ferent families as inhabiting Italy are : — 
Mygalidte 
Filistatidae 
Scytodid£B 
DysderidaB 
Drassidao . 
Therididae .
