Spiders and Their Near Relatives 



Family PHALANGODID^E (Phal-an-god'i-dae) 



In this family the hind coxae are united to the first abdominal 

 segment at the base, but are free at the apex. The second pair 

 of legs have distinct endites. The pedipalps are robust and about 

 as long as the body. The spiracles are indistinct. 



Our Phalangodidae represent five genera; 

 these can be separated by the following table: 



A. Tarsus of the last pair of legs furnished with 

 a simple single claw. P. 61. Cyptobunus 

 AA. Tarsus of the last pair of legs furnished 

 either with a compound claw or with 

 two simple claws. 

 B. Tarsus of the last pair of legs with 

 one compound claw; palpi not as long 

 as the body; eyes present. P. 63. 

 BB. Tarsus of the last pair of legs with two simple claws. 

 C. Eye-tubercle arising from the anterior margin of the 

 cephalothorax; palpi shorter than the body. P. 04. 



Sitalces 

 CC. Eye-tubercle back from the margin of the cephalo- 

 thorax; palpi longer than the body. 

 D. Tarsus of the second legs about twice as long as the 

 body, its segments very slender; eyes absent. 

 P. 64. Phalangodes 



DD. Tarsus of the second legs about as long as the body; 

 eyes often present. P 62. Scotolemon

The only known 

 representative of 

 this genus was 

 recently discovered 

 by Professor Coolev 

 in a cave in .Mon- 

 tana and was de- 

 scribed by Mr. 

 Banks. It differs
