Mr. Templeton on certain Spiders. 
Explanation of the Figures. 
PraTE XVII. 
Dysdera H. Templetoni, female. 
——= tale. 
Seen in profile. 
Anterior superior part enlarged to shew the position of the eyes. 
The eyes seen from before. 
seen from above. 
The mandibles from behind, with 2 teeth on the nearer edges 
of the cavity for receiving the claw, and one on the farther. 
The maxilla and posterior lip; the inner labial edges of the 
jaws are membranous and pass behind the lip, the jaw 
becoming suddenly, not gradually, incrassate. 
The palpus of the female. 
Oonops pulcher, female, 
Profile. 
Eyes seen from above. 
in front. 
Mandibles. 
Parts of the mouth. 
Male palpus. 
A hair from the palpus of the female to shew its serrated 
structure. 
Tip of the hind leg, to shew the appendicial joints and the 
claws, with the little pellucid body between on its 
peduncle, 
the position of each focus ; they are not numerous, being in the pedal arteries 
about two or three times their own length asunder, one only passing at once 
through the tube: in the veins however they lie closer together, 
I remember last year seeing what I thought was the motion of a fluid in the 
legs of Ciro alatus. If this observation was correct, accurate examination may 
make this a test of the position of these minute tribes: it lies open to future 
investigation.
