74 ARACHNIDES OF THE 



Cabinet of the Academy. 



Body spheroidal, somewhat oval, glabrous, po- 

 lished, black ; head longitudinally semi-oval : eyes 

 sessile, near the base of the head each side, remote ; 

 feet hairy, pale testaceous, subequal, shorter than 

 the body. 



I found this species several times under stones, 

 &c. It is sluggish in its movements, like other spe- 

 cies of this genus ; when alarmed or in danger the 

 feet are thrown forward together over the mouth, 

 and the whole of the thorax is then deflected upon 

 the anterior part of the body ; in this state the gene- 

 ral form is a solid oval. 



genus EDELLA. Latr. 



Palpi elongated, terminated by setae ; rostrum 

 j conic ; eyes four ; posterior feet longest. 



Species. — R. *oblonga. Body oblong-oval, bright 

 red, paler in the middle and beneath, with a few 

 scattered hairs ; rostrum nearly half as long as the 

 body, with two or three pairs of stouter hairs ; palpi 

 four jointed, resembling arms; first joint destitute of 

 hairs and longer than the others conjunctly; second 

 and third joints very short; fourth joint longer than 

 the two preceding ones, attenuated towards the base 

 and truncated at tip, with several short hairs and 

 two terminal setse longer than itself, of which the 

 inner one is rather shorter; feet hairy, subequal, 

 pale, the posterior ones rather longer.
