SADALA.—OLIOS. 67 
to be of his genus Sadala, the characters of which, however, as given by him (J. ¢. 
antea) would seem to need revision in order to include it. 
VINDULLUS, Simon, 
Formed for a spider from Brazil, nearly allied to Sparassus, by Mons. Simon (Actes 
de Ja Soc. Linn. de Bordeaux, xxxiv. p. 288). The specimen from which a new 
species has been described below has been examined by M. Simon, and determined to 
be of this genus. 
Vindullus similis, sp. n. 
Adult female, length rather over 4} lines. 
This spider (in the cabinet specimen) is of a uniform yellow, the abdomen being paler than the rest, and 
clothed with pale hairs. 
The cephalothoraw is distinctly longer than broad; profile rather flattened convex. Caput moderately broad, 
and rather roundly truncated anteriorly on the upper margin; the height of the clypeus is equal to 
the diameter of one of the fore central eyes, and the lateral marginal indentation of the caput is tolerably 
strong. 
The eyes are small, pale brownish coloured. Those of the fore central pair are slightly the largest. The anterior 
row is straight, though it looks curved in some positions owing to the curvature of the fore margin of 
the caput; its eyes are equidistant from each other. The posterior row is longest and very slightly 
curved, the convexity of the curve directed forwards ; the interval between the central pair of this row 
is distinctly, in fact considerably, greater than that between each and the lateral eye next to it of the 
same row. (In M. Simon’s characters of the genus the eyes of the posterior row are stated to be equi- 
distant from each other, and the four centrals to form a square, whereas in this species they form a 
trapezoid or square, whose posterior side is distinctly longer than the other three sides, which are equal.) 
The legs are very slender, 2, 1, 4, 3; on the upper side of the fore half of the metatarsi and throughout the 
tarsi are two parallel red-brown, not very distinct, longitudinal lines. They are furnished with rather long 
pale hairs, a thin scopula, and claw-tuft. The spines are long, tolerably strong, sessile, and of a brownish- 
red hue; the most conspicuous are beneath the tibis and metatarsi—three pairs in two parallel rows 
under the tibise, and two pairs under the metatarsi, the latter being the longest and strongest. 
The palpi are similar in colour and armature to the legs. 
The mawille are moderately long, enlarged and rounded at the extremity, and slightly inclined to the labium, 
which is about equal in length and breadth, but rather widened and rounded at the apex. 
The falces are moderately strong, vertical, and straight, their profile not greatly convex. 
The abdomen is of moderate size, rather roundly truncated anteriorly, and somewhat tapering to the spinners, 
which are short and compact. The form of the genital aperture is simple but characteristic. 
Hab. GuatTeMALa, Chisec (Sarg). 
Mr. Sarg says that when caught this spider was of a bright green hue. 
OLIOS, Walckenaer (partim). 
Olios erroneus, sp. n. 
Adult female, length 7-73 lines. 
The whole of the fore part of this spider, except the falces, is of an orange-yellow colour, and the abdomen is 
of a paler, more clayey hue. The underside of the abdomen has a broad longitudinal dusky-blackish 
band with a pale margin. The falces are deep reddish-brown. 
The cephalothorav is longer than broad ; profile flattishly curved.
