close together and nearly parallel to each other, backwards from 
between the two hind central eyes towards the small indentation 
above mentioned. 
The eyes are small, but do not differ much in relative size. They 
are arranged in two transverse nearly straight rows, the hinder row 
being the longest, and its eyes equidistant from each other; those 
of the front row, which is straight and placed immediately above 
the lower margin of the clypeus, are also equidistant from each other. 
The falces are strong, projecting, and rather prominent near their 
base in front, also slightly excavated at their inner extremities. 
They are of a dark reddish-yellow colour, and furnished with a few 
projecting, black, bristly hairs in front. 
Legs strong, moderately long, and of a clear yellow colour. They 
are armed with a few black spines of various lengths, those beneath 
the fore legs being the longest ; the metatarsi and tarsi of the first 
two pairs are thickly clothed beneath with short close-set brown 
hairs ; each tarsus has some papilleeform hairs on its underside, and 
terminates with two curved and pectinated claws, beneath which is 
a small scopula. 
The abdomen is of a dull yellow colour, clothed with yellow-grey 
hairs; in the median line of the fore part, on its upperside, is a 
narrow stripe of a clearer yellow than the rest, and pointed at its 
hinder extremity ; on either side of the posterior half of this stripe 
are two small dark punctures or depressions ; the four form a square 
the fore side of which is rather narrower than the hinder one. The 
spinners are rather long and prominent, and the external sexual 
organs sufficiently conspicuous, though not very large, the aperture 
having the form of the Greek omega. Possibly the specimen here 
described may be the female of some already described male; but 
in the absence of examples of males from the same locality as the 
present specimens, it seems best to describe it and give an accurate 
figure of its sexual aperture; the form and structure of this part 
seems to be the best differential specific character among the many 
very similar females of this group of the genus Cludiona.
