GEOGRAPHICAL REGIONS AND THEIR PRINCIPAL GENERA. 
Mediterranean Region. 
Dipluridee. 
Diplurine.—Brachythele: Greece, Cyprus, Central Asia. 
Macrotheline.— Wacrothele: Spain, China, LooChoo. Phyxio- 
schema: Transcaspia. 
Brachybothriidee.— A cattyma: Japan. 
Atypide.—Atypus: South and Central Europe, Algeria, Japan. 
Calommata: Japan. 
Cyrtaucheniidee.—Wemesia: 8. Europe, N. Africa, China. <Ane- 
mesia: Afghanistan. Cyrtauchenius : Southern countries 
of Mediterranean. <Amblyocarenum: 8S. Europe, N. 
Africa. 
Ctenizide.—Pachylomerus: Spain, Algeria, Japan.  Jdiops : 
Syria. Cteniza: France, Italy. dpycephalus: Sicily, 
Sardinia. Cyrtocarenum: Eastern countries of Medi- 
terranean.  Sterrhochrotus : Turkestan.  Latouchia : 
Loo Choo Islands, China. 
Halonoproctidee.— Halonoproctws : China. 
Barychelidee.—Leptopelma: 8. Italy, N. Africa. 
Aviculariidee. 
Aviculariinse.—Tschnocolus: 8. Europe, N. Africa. Crator- 
rhagus and Chetopelma: Eastern area of Mediterranean. 
Of the above-mentioned genera, 22 in number, those belonging to 
the Aviculariide and Barychelide are peculiar ; also Sterrhochrotus, 
Cyrtocarenum, Zpycephalus, and Cteniza amongst the Ctenizide ; 
Cyrtauchenius, Anemesia, and Nemesia amongst the Cyrtau- 
chentide; Phyxioschema amongst the Dipluridz; and perhaps 
Acattyma amongst the Brachybothriide. Of the others, Brachy- 
thele and Amblyocarenum are also Sonoran ; J/acrothele and 
Latouchia also Oriental; Atypus, Orientaland Sonoran; Calommata, 
Oriental and Ethiopian; Pachylomerus, Sonoran and Neotropical ; 
Idiops, Oriental, Ethiopian, and Neotropical. 
Thus of the 22 genera enumerated, more than half, namely 12, 
are peculiar. Of the rest, 4 are Sonoran and 5 Oriental, the latter, 
with exception of /diops, occurring in the Indo-Chinese area ; 
2 Ethiopian and 2 Neotropical. With the Australian Region the 
Mediterranean has no genera In common, although Porrhothele 
and Stenygrocercus of the former are nearly related to MJacrothele 
and Phyxtoschema of the latter. These data make it impossible 
to attach the Mediterranean area to either of the others with 
which it has genera in common. Hence it must be regarded as a 
Region apart. The only genus which extends into the Holarctic 
is Atypus. 
It may be defined as the Region lying north of the Ethiopian 
and Oviental Regions, and south of the great mountain-chains of 
urope, north of which the Mygalomorphe, excepting Atypus, 
do not pass.
