156 T. THORELL, 
with the spider described by KEYSERLING 1) as St. tenaria, which, as SCHIÖD- 
TE suspected, is quite a different species from the genuine St. tenaria 
so accurately described by this latter author. This is in fact easily 
seen since the appearance of SCHIGDTES paper: On the genus Stalita ?), in 
which special attention has been paid to the points in which the last men- 
tioned spider differs from KEYSERLING’S description. Of KEYSERLING'S spe- 
cies I possess a full-grown 9, 8"" long, exclusive of the mandibles, which 
are of 2™ length; it agrees in every essential particular with the descrip- 
tion given by KEYSERLING. The length of the cephalothorax is 5"", and 
the breadth full 3", the breadth of the pars cephalica little more than 2". 
The length of the pars cephalica is a little greater than its breadth, and 
it is tapering behind. The mandibles are thinly covered with hairs on the 
whole of the dorsal surface, but more thickly hairy at the extremity, along 
the claw-furrow. The posterior edge of the claw-furrow has two teeth. 
The last joint of the palpus is longer and slenderer than the preceding 
joint. The patellæ are destitute of spines. The superior tarsal claws are 
long, slender, and much curved, with about 13 long, closely set comb-teeth; 
the toothless part of the claw is very long and much bent downwards. The 
inferior claw is long, slender and abruptly inflected downwards, and without 
teeth. All this refers to the 1* pair of legs. On the 4" pair the claws 
are still longer and slenderer, with about 6 divergent teeth near the base. 
The palpal claw is small and toothless. The abdomen is 42™ long and 
21"* broad, with thin fine hairs. The posterior stigmata are as broad as 
the anterior. 
A particular interest is attached to this spider, (which I call S. 
Schicedtei), from the circumstance of its having six rudimentary eyes! In 
position these eyes agree nearest with those of Ariadne (which genus also, 
like Stalita, has 3 claws on the tarsi). They are small like points, about 
equal in size, and rather lighter in colour than the cephalothorax, and there- 
fore easily visible with a good common magnifying lens, and occupy an 
area the breadth of which is about a third of that of the head, and which 
is about three times as broad as it is long. They are arranged in two 
rows very near the margin of the'clypeus, 4 eyes in the posterior, and 2 
in the anterior row. The posterior row is straight and considerably longer 
than the anterior. The two posterior central eyes are somewhat nearer to 
each other than to the lateral eyes. The distance between the two lateral 
eyes is about two eye-diameters, and perhaps somewhat greater than the
