The total number of species belonging to South America is com- 
puted at 248. 
These brief extracts from Dr. Goeldi’s paper, which is written in 
Portuguese, will give some idea of its value to students in Brazil 
desirous of becoming acquainted with work already done amongst 
the Theraphoside of South America. 1 have to thank Dr. Goeldi 
for the opportunity he has given me of perusing these publications 
during my brief visit to the Para Museum in January 1896. 
Suborder MYGALOMORPH 2, Pocock, Oct. 1892. 
It is not altogether easy to decide which of the various subordinal 
names proposed for this group of Spiders is the most suitable and 
therefore to be retained. We have first of all the ancient division of 
the order by Walckenaer into two large suborders under the names 
“« Thérophoses” and ‘ Araignées” (Ins. Apt. tome i. 1837, p. 38). 
These are of the same value as the “ Mygalées” and “ Aranées” of 
Dugés (‘Observation sur les Aranéides,” Ann. Sci. Nat. sér. 2, 
tome vi. 1836, p. 162). Next we have the subordinal division made, 
under the names of ‘* Quadripulmonaires” and ‘ Bipulmonaires,” by 
Dufour (“ Arach. Quadripulmonaires,” Ann. Gén. Sci. Phys. vol. iv. 
1820), equivalent to the Tetrapneumones and Dipneumones of 
Latreille, these names being of course based upon the possession 
of one pair or two pairs of lung-books. 
Later, in 1870, we find the whole order subdivided into seven 
suborders—the Orbitelarie, Retitelarie, Tubitelarie, Territelarie, 
Citigrade, Laterigrade, and Saltigrade—by Dr. Thorell, corre- 
sponding, as he himself tells us, with the almost similarly named 
families of Latreille, of which the suborder Territelarie corresponds 
to the Thérophoses, Mygalées, and Tetrapnewmones of the earlier 
authors. 
In his Hist. Nat. Araign.i., Oct. 1892, p. 61, M. Simon recognizes 
two suborders under the double names “ Aranew Theraphose” and 
“ Aranee Vere” —the former including Liphistius and the families 
Aviculariide and Atypide; the latter the Hypochilide (a tetra- 
pneumonous form) and every other known family. 
In October of the same year Mr. R. I. Pocock, in a paper on 
the Classification of Spiders (Ann. Mag. Nat. Hist. ser. 6, x. 
p- 306), has divided the order Aranez into two main divisions— 
the Mesothele, including the family Liphistiide, and the Opistho- 
thele, including every other known family. These two divisions 
are based upon the position of the spinning-appendages in the 
middle of the ventral area or at the distal end of the abdomen.
