be regarded as sufficient to warrant tlie establishment of a 
family, much less to serve for the primary division of an order. 
Blackwall, indeed, speaks of its ” convenience but little can 
gained even in this respect when we find that, of 315 species 
described in the present work, 307 belong to one group and 
only 8 to the other, whilst the disadvantage of separating Dys- 
dera and Segestria from the Drassidae, to which they are mani- 
festly so closely allied, furnishes a strong argument against the 
adoption of this principle of elassification. 
The arrangement of the families is as follows : — 
Tribe Octonoculina. 
Fam. Mygalid(B. {Atypus, 1 sp.) 
Fam. Lycosidce. {Lycoso., 16 sp. ; Dolomedes, 3 sp. ; Ileca’erge, 1 sp. ; Sphasus, 
1 sp. : total 21 sp.) 
Fam. Salticidco. {Eresus, 1 sp. ; Salticus, 17 sp. : total 18 sp.) 
Fam. Thnmisidce. {Thomisusy 19 sp. ; Philodromus, 9 sp. ; Sparassusy 1 sp. : 
total 20 sp.) 
Fam. Drassidce. {Drassus, 14 sp. ; Cluhionay 12 sp. ; Aryyronetay 1 sp. : total 
27 sp.) 
Fam. CAmflomdce. Spinners 8 ; tarsi 3-clawed ; posterior legs with a 
calamistrum or cnrling-apparatus of two parallel rows of short, moveable 
spines. {Cinif oy 5 sp. ; Ergatisy 3 sp. ; Veleda, 1 sp. : total 9 sp.) 
Fam. Agelenidae. {Agdena, 9 sp. ; Tegenaria, 4 sp. ; CceloteSy 1 sp. j TeodriXy 
1 sp. : total 15 sp.) 
Fam. TheridiidcB, {Thcridiony 27 sp. ; PhoIcuSy 1 sp. : total 28 sp.) 
Fam. Lmyphiidoi. {Linyphia, 33 sp. ; Neri'ene, 48 sp. ; Walckenaertty 33 sp. ; 
Pachygnathtty 3 sp. : total 117 sp.) 
Fam. FpexridcG. (Epeira, 31 sp. ; Tetragncdha, 1 sp. : total 32 sp.) 
Tribe Senoculina. 
Fam. Dysderidee. {Dysdera, 3 sp. ; Segestriay 2 sp. ; SchcenobateSy 1 sp. ; OonopSy 
1 sp. : total 7 sp.) 
Fam. Scytodidee. (^Scytodes, 1 sp.) 
Simonas Histoire naturelle des Araignees (Paris, 1864) presents 
a classification differing in many respects from those of his pre- 
decessors, agreeing with that of Blackwall in the limits of several 
of the families, but suppressing others altogetlier, and departing 
from it rather widely in the general arrangement. 
Ilis classifieation is as follows : — 
/ 
Fam. 1. Scytodiformes {Seyfoda, Omosita, Pholciis, &c.). 
2. Mygaliformes {My gale, Atypus, Sphodros, &c.). 
3. Et'assiformes (Segestria, FiUstata, Drassus, Eysdera, Argyronefa, 
Clvhima, Anyphtxna, ko,.) — Drassidce Ciniflonidcc DysderidcB 
(Black w.).
