greyish-yellow and darker hues, and with numerous prominent 
bristly ones. 
Along the middle of the fore half of the upperside is a largish 
paler yellow-brown somewhat oblong marking, enlarging to its 
hinder extremity, where it has three divergent points. On the 
middle of the hinder part of this marking is a longitudinal dark- 
brown patch; following this, towards the spinners, are several 
indistinct, curved, pale transverse lines. The underside is pale 
yellowish brown. 
This species was founded upon a Spider received in a dried and 
pinned state from Mr. T. J. Melliss, by whom it was captured in 
the island of St. Helena. The legs were set out laterally ; and the 
various structural characters of the Spider presenting a striking 
agreement with some of the Thomiside represented by the genus 
Olios, led me at the moment toinclude it in that genus. Subsequently, 
however, I received a fine well-conditioned example in spirit of 
wine, and at once saw that it was not a laterigrade Spider at all, but 
belonged probably to some unknown genus of Drasside. This is 
also confirmed by the opinion of Mons. Simon, to whom I lately 
sent it for examination, its nearest allies being probably the genus 
Clubiona, 
ARACHOSIA, g. n. (nom. propr.). 
Cephalothorax oval; lateral marginal constrictions well marked ; 
anterior portion of caput (at the insertion of the falces) truncated in a 
straight line, the corners being a little prominent ; profile-line even 
and almost level, very slightly highest at the beginning of the pos- 
terior slope. 
Eyes small, and not greatly different in size, in two transverse rows, 
of which the anterior (or lower one) is nearly straight, and the pos- 
terior very strongly curved; the convexity of the curve directed 
backwards. The eyes of the lateral pairs are pretty widely sepa- 
rated. 
Legs not very long, strong, 4, 3, 1, 2 (3, 1, and 2 being very nearly 
of equal length), armed with hairs and slender spines; terminal 
tarsal claws two, with claw-tuft and scopula (not dense) beneath the 
tarsi and metatarsi. 
Falces moderately long and strong, prominent at their base in 
front, and a little directed forwards. 
Mawille rather long, straight, sides nearly parallel, rounded on 
the outer sides at their extremity, and obliquely truncated on the 
inner sides. 
Labium about half the length of the maxilla, oblong, and rounded 
at apex. 
Sternum oval, pointed behind. 
Abdomen elongate-oval, of a somewhat cylindrical form, fitting 
fairly up to but not over the thorax; at the middle of the 
underside is a largish transverse curved slit or aperture, leading 
doubtless to a respiratory apparatus. This aperture is eavered with
