=~ CLASSIFICATION 387 
pendent chelicerae, the paturon directed forward and the unguis or 
fang articulating in a vertical plane. The eyes are eight (except 
Masteria, six), usually compact, and situated on an eminence. 
Pedipalpi very leg-like, and palpal organs of male simple. No 
maxillue. Four pulmonary stigmata. Spinnerets normally four. 
No eolulus. | 
The Avicularidae inhabit the warmer portions of the world, 
and are entirely unrepresented in this country. The monster 
spiders which excite wonder in zoological collections belong to 
this group, as do the moderate-sized “ Trap-door ” Spiders which 
are found abundantly in the Mediterranean region. 
The Family has been divided into about a hundred and fifty 
genera, nearly half of which, however, contain only a_ single 
species. 
They have been grouped by Simon!’ into seven sub-families, 
PARATROPIDINAE, ACTINOPODINAE, MIGINAE, CTENIZINAE, BARy- 
CHELINAE, AVICULARIINAE, and DIPLURINAE, of which the first 
three may be dealt with very briefly. 
(i.) The PARATROPIDINAE include only two American species, 
Paratropis scrupea from the Amazon, and Anisaspis bacillifera 
from St. Vincent. They have thick, rugose integuments, and the 
internal angle of the coxa of the pedipalp is produced. The 
labium is fused with the sternum, which is very broad. Nothing 
is known of their habits, but as they do not possess a “ rastellus ” 
(see p. 320) they are probably not burrowing spiders. 
Gi.) The AcTINOPODINAE comprise three genera, Sfasinopus 
represented by a single South African species, S. caffrus ; Hriodon, 
of which about ten species inhabit Australia; and Actinopus, of 
which about ten species are found in Central and South America. 
They have the coxae of the pedipalps very short and broad, and 
somewhat produced at the internal angle. The eyes are not in 
the usual compact group, but are somewhat extended across the 
caput. Actinopus burrows a deep cylindrical hole lined with 
sulk, and furnished with a round, bevelled trap-door. 
ii.) The sub-family MIGINAE is established for the reception 
of three genera, Moggridgea (South Africa), Migas (Australia and 
South-West Africa), and Myrtale, whose single species, JZ. perroti, 
inhabits Madagascar. They are chiefly characterised by their 
very short and downwardly-directed chelicerae. They are not
