other species. The groups Orbitelarice and Retitelarice are considered 
unlit for systematic arrangement, representing merely economic charac- 
ters. The author’s group Cribellata includes all the genera characterized 
by the cribellum and calamistrum, and is divided into nine families — 
Zoropidce , Miagrammopidcc , Filistatidce, (JEcobiidce , Dinopidce, Uloboridce , 
Dictynidca , Eresidai , and Amaurobiidce. The author accounts for the 
absence of the calamistrum in adult males of the group, as the probable 
result of this sex not forming snares in the adult stage. 
An abstract of this author’s memoir on the structure and function of 
the so-called liver in Spiders [Zool. Rec. xviii. Arachn. p. 6] is given in
