Eyes of anterior row forming a straight or slightly procurved line. Centrals either equal to or slightly larger 
than the laterals. Eyes of posterior row forming a straight or slightly procurved line, broader than the 
anterior row; eyes approximately equal and equidistant. Clypeus very narrow, about half the diameter 
of one of the anterior eyes, sometimes more. Superior margin of fang-groove with two, inferior with two, 
three, or four teeth. Central quadrangle quadrate or longer than broad ; smaller in front.

* §. argelasius, Walck., was selected as the type of the genus Sparassus by Thorell in 1869-70. Walckenaer’s 
name might be held to be a “ nomen nudum *” were it not for the generic diagnosis, and the fact that his species 
is well known under the synonym S. spongitarsus (Duf.) (cf. Simon, Ann. Soc. Ent. Fr. 1875, p. 334, nota 2), 
Sparassus argelasius, Latr., requires a new name, 
O. spongitarsus (Duf.) is the type of Olios, Walck. Olios is therefore a synonym of Sparassus. 
If S. argelasius, Walck., be regarded as not the type, then S. pallens (Fabr.), the second and only other 
species included in Sparassus, after Mecrommata virescens has been withdrawn, will become the type. In no 
case can S. argelasius, Latr., be the type. 
In selecting the type of this genus in Hist. Nat. Araign. éd. 2, ii. 1, p. 46, M. Simon appears to have 
forsaken the principle laid down in Hist. Nat. Araign. éd. 2, i. p. 848. 
Norr.—Referring to the synonymy of Acrosoma and Micrathena, Simon remarks that where the type has not 
been designated, the oldest species shall be regarded as the type. Araneus pallens, Fabr., is certainly older 
than Sparassus argelasius (Latr.), and should therefore, on this principle, have been selected as the type.
