of the Genera of the Aranee. 63 
If, however, in the original diagnosis of Micromata, 
Latreille had included any character which would have 
definitely excluded A. accentuata, then it might be possible 
to act on this fact. 
But Latreille’s original diagnosis of ‘ Les Grottiformes,” 
Walck., is ‘‘ Machoires droites, quatritme paire de pattes la 
plus longue” (Nouv. Dict. p. 135, 1804) ; characters which 
apply equally well to the well-known European A. accentuata. 
It is perfectly clear that Latreille and Walckenaer both 
wished accentuata to be dissociated from the other three 
“ orottiformes,”’ and neither of them cared what became of 
the original name Micromata; the author sunk it as a 
synonym, while Walckenaer swamped it under his new name 
Sparassus. 
It is, however, the duty of science to restore Micromata as 
a generic name, and it is impossible to enter into the question 
of the wishes and sentiments of authors. This would simply 
end in a labyrinth of inconsistencies and endless disagreement 
and disputation. For, if we are to consider the wishes of 
either of these authors in connection with the signification of 
Micromata, why ignore their conjoint wishes in regard to the 
name itself ? 
If we take this line, why are we not also to accept the 
names substituted by Walckenaer in those cases where he 
considered them more suitable than others previously given 
to the saine genus or species by other authors? Thorell and 
Simon both select vzrescens, Clerck, as the type. 
Type, Icromata accentuata (Walck.), 1802. 
OxyopEs, Latreille, 1804, Nouv. Dict. xxiv. p. 135, col. 2, 
line 12. 
A single species only included—Aranea heterophthalma. 
Type, Oxyopes heterophthalmus, Latr., 1804.

‘'wo species were originally included, namely those men- 
tioned under ‘‘ Les Coureuses ” by Walckenaer, Faun. Par, 
p- 235 :—(1) A. mirabilis, Clerck, pl. v. fig. 10; (2) A. mar- 
ginata, De Geer, t. vil. p. 281. 24. 
The latter is identical with Araneus jfimbriatus of Clerck 
and was selected as the type of the genus under “ Araignée 
loup bordée,” De Geer, in 1810, by Latreille. A. mirabilis 
was in 1887 referred to Ocyale, Sav. ; but the type of Ocyale
