Species of Oriental Mygalomorplige. 179 



externally and internally with thick fringes of long silky 

 hair, the femora also, especially the anterior pair, with a 

 strong external fringe ; all the scopulaj wide, well-developed, 

 and entire, except that on the fourth protarsus, which is 

 divided and extends over the distal third of the segment, the 

 scopula on the lower surface of the third protarsus covering 

 nearly the whole of the segment. 



(Spinners fractured.) 



Measurements in millimetres. — Length of carapace 20, width 

 18'5 ; length of palp 38, of first leg 69, of second and fourth 

 about 63, of third 52. 



A single female specimen, ticketed ' East Indies,' possibly 

 from Pinang, since the specimen was taken from a bottle 

 which also contained an Omothymus. 



Family OrnithoctonidaB, nov. 



Mandible furnished externally and below with a dense pad 

 (scopula) composed of short feather-like hairs ; the area below 

 this pad smooth, but bearing at the base a small number of 

 large, curved, barbed setae, which spring from the scopula 

 above. The adjacent surface of the maxilla sparsely setose, 

 but armed above and below the suture with tuberculiform 

 spines. Pads on the tarsi large and entire. Tibiai and pro- 

 tarsi of legs apically spined. 



Synopsis of Genera. 



a. Legs of the fourth pair measured from base of 



lemur longer than those of the first and no- 

 ticeably stouter ; their tibitie thicker than their 

 femora, and, like the protarsi, spiuulose .... Citharotjncithus, uov. 



b. Legs of the fourth pair not longer than those 



of the first, and thinner; their tibiae much 



narrower than their femora. 



a\ Legs short and robust; -width of anterior 



and posterior tibite more than a thiid of 



their length; ocular tubercle small; clypeus 



wide OrnMoctotius, Poc. 



b^. Legs longer and thinner ; width of anterior 

 and posterior tibice less than a third of 

 their length. 

 a^. Carapace high ; ocular tubercle small, 

 high, not much wider than long ; cly- 

 peus longish Meloposns, nov. 



b^. Carapace lower; ocular tubercle low, very 

 wide, nearly twice as wide as long ; 

 clypeus short, 

 o^. Sternum oval, as wide between the 

 tirst coxa? as between the third (tarsal 

 pads wider, protarsal pads shorter, pro- 

 tarsi slenderer) Omothymus, Thor. 



b^. Sternum narrowed in front, much wider 

 between the third than between the 

 tirit coxa3 I'horminr/vchiltis, uov.
