484 Mr. F. Pickard-Cambridge—A Revision 
following the safest course for the avoidance of disputation 
as to the meaning of words and phrases. No one can ever 
dispute the fact that immediately after Lycosa Latreille wrote 
Les Chasseuses de Walck., and this is the only point that is 
not open to dispute. He did not write “Vagabondes Div.*,” 
though he possibly intended to do so. We cannot, however, 
concern ourselves with possibilities, but simply with the 
species included under the denomination which he did write 
after his genericname. ‘This, at least, is my own position in 
the matter, acting in strict accordance with the rules I am 
following. 
(1) Including only the species under Les Chasseuses, we 
have left in, under Lycose proprie, by Sundevall (Vet.-Akad. 
Handl. 1832, p. 173), when he made his new genera T'arentula 
and Pirata, two only of the original species, L. sylvicola 
(=lugubris) and L. amentata (=saccata). In 1848 C. L. Koch 
refers amentata (under the name paludicola) to his new genus 
Leimonia ; while he refers /ugubris (ander the name alacris) 
to his new genus Pardosa, but on a later page of the same 
work. This species, being the last left in, remains as the 
type of the genus Lycosa. 
(2) If we take into consideration Les Chasseuses, plus Ar. 
tarentula and Ar. saccata, Latreille’s Vagabondes Div.%, 
then we shall find the type to be Ar. tarentula, since this 
author cited it himself in 1810. Simon is perfectly correct 
in his conclusion as to the type, and in his ‘ Arachnides de 
France’ shows that he too respects a selected type, for he 
says: “ Les Lycosa tarentula on été choisies par Latreille 
comme types du genre Lycosa.” 
Type, L. tarentula. 
(3) If we ignore, as does Dahl, Latreille’s citations in 
1810, then we have to pass on to consider Sundevall’s action 
in 1832 when he founded the genus Tarentula. Sundevall 
does not mention the species L. tarentula by name, and it 
cannot therefore be taken into consideration. 
Dr. Dahl says: ‘ According to the definition of the sub- 
genera, this species must be included im the subgenus 
Tarentula.’ Now this action is absolutely inadmissible, 
because according to our rules we cannot admit into any 
generic group a species not actually included by name, or 
directly referred to, at the time when the genus is founded. 
Lycosa tarentula cannot be the type of Tarentula, Sund. 
We have, then, two courses open to us. If we include 
Ar. tarentula at all in the original group under Lycosa, then 
this species is its type. If we do not include this species,
