526 ARANEIDEA. 
short, semierect spines beneath. Abdomen elongate, not transverse, covered with a horny integument 
and armed with from 2-10 or more sharp spines or protuberances. Spinners contained at the end of a 
horny tube. 
Males differing very much in general appearance from the females; when immature the two sexes are almost 
alike, but in the adult male the spines become atrophied and then it is, in most cases, impossible to pair 
them unless they have been taken together. 
The species known to me may be recognized by the following characters :— 
Males. 
A. Coxa i. without apical hook beneath; femur ii. without groove 
above at the base. 
i. Integument of carapace and abdomen finely granulose or coarsely 
punctured throughout. 
a. Abdomen broader in proportion, terminating in two spini- 
form cusps. Integument covered with minute granules 
b. Abdomen narrower in proportion, terminating in four spini- 
form cusps. Integument covered with coarse rounded 
punctures . see a 
. Integument of carapace and abdomen neither granulose nor 
punctured. 
a'. Abdomen broader behind. 
a’, Legs entirely devoid of spines. 
a’. Tarsal hook with one branch only, set at a right angle to 
the shaft . 
b°. Tarsal hook with two branches. 
a‘. Branches of tarsal hook subequal, the hook itself 
T-shaped. 2. 1. 6 ee ee ee ee

enormously protonget slender, and sinuous, horn- 
like .. . 
b. Legs, at least femur i. and tibia il., ‘furnished with
