The underside is of a uniform pale yellow, and the genital aperture is of a dark yellow-brown colour and 
characteristic form.

THANATUS, C. L. Koch (fam. Thomiside). 
Thanatus longipes, sp. n. 
Adult male, length 33 lines. 
Cephalothorax dark yellow-brown, somewhat finely veined on the sides, and narrowly margined with black, 
and with a broad pale yellow-brown band, a little constricted in the middle, extending along the upperside 
from the eyes to the hind margin. This band is thickly clothed with coarse white hairs. The clypeus is 
prominent, and its height considerably exceeds half that of the facial space. 
The eyes of the posterior row are separated by equal intervals, and the interval between each of the outer eyes 
of this row and the outer eye of the anterior row on its side is equal; these eyes with the hind-central 
eye on its side form an isosceles triangle, whose base is half its height in length. The two fore-central 
eyes are separated by double the interval that divides each from the fore-lateral eye on its side, this last 
being about an eye’s diameter. The four central eyes form a square, whose anterior side is shorter than 
the rest. 
The legs are long, 1, 2, 3, 4, of a pale yellow-brown hue, thickly mottled and speckled with dark brown, 
furnished thinly with hairs and fine spines, and a thin scopula beneath the tarsi and the anterior portion 
of the metatarsi. 
The palpi are moderately long, similar to the legs in colour; the radial and cubital joints are of very nearly 
equal length, the latter has a short, stoutish, pointed dark red-brown apophysis at its fore extremity on 
the outer side, and an obtuse one beneath it. The digital joint is of a narrow-oval form, and about equal 
in length to the radial and cubital joints together. The palpal organs are simple, consisting of an oval 
lobe, with a short black spine at their extremity. 
The maxille, labium, and sternum are similar in colour to the legs, the sternum being more coarsely and thickly 
speckled with deep brown, forming a longitudinal central and a lateral marginal stripe. 
The abdomen is oval, of a mottled yellow-brownish colour, furnished with hairs, of which a few are coarser 
than the rest and black; a longitudinal tapering dark brown band occupies the middle of the upperside, 
and is produced in a somewhat broken form to the hinder extremity; the fore end of this band does not 
quite reach the fore margin of the abdomen; and on each side of its hinder extremity are three black 
spots forming a rather conspicuous curve, whose convexity is directed outwards. On the underside are 
two curved longitudinal indefinite dark brown lines enclosing a long pointed oval space. Spinners short 
and compact. 
Hab. Mexico, Omilteme in Guerrero (H. H. Smith). 
CLUBIONA, Latreille. 
Clubiona crocota, sp. n. 
Adult male, length 24 lines; female, 33 lines. 
In general form and appearance this spider is of the ordinary type. The whole of the fore part of the male is 
of a pale orange-yellow colour, and the abdomen is of a more luteous yellowish hue. 
The eyes are of nearly uniform size and all pearly-white ; they occupy the whole width of the upperside of the 
fore extremity of the caput. The posterior row, looked at from above and slightly behind, is straight ; 
the anterior row curved, the convexity of the curve directed forwards ; looked at from in front the posterior 
row appears well curved. The interval between the hind-central pair is equal to nearly two diameters, 
while that between each and the hind-lateral eye on its side is not much more than one diameter, and 
a similar interval separates each of the hind-central pair from the fore-central eye opposite to it. The four 
central eyes form a trapezoidal whose posterior side is the longest and its anterior side the shortest, the
