Melognathus/ gen. nov. 



Anterior row of eyes distinctly procurved, with the median eyes 

 clearly larger than the lateral. Posterior median eyes smaller than 

 the lateral. 



Fovea thoracica short; transverse. Cephalothorax low; pars 

 cephalica scarcely elevated, not convex. 



Vibratile bristles of stridulating organ on the chelicera few, in a 

 series a little ectad of and parallel with the oral fringe, bacilliform. 

 The stridulating spines of the opposite adjacent surface of coxa of 

 pedipalp below suture arranged in two definite series close to and 

 parallel wuth the suture, not at right angles to it as in Thrigmopoeus ; 

 those above the suture few, smaller, and scattered among plumose 

 bristles (Plate 5, fig. 6). 



All tarsi scopulate with no trace of a dividing setose band in the 

 scopulae. IMetatarsi of anterior legs scopulate nearly to base; meta- 

 tarsi III and IV scopulate only at distal end. Metatarsi of posterior 

 legs armed at distal end both above and below with stout spines. 

 Tibia + patella I decidedly longer than tibia + patella IV. 



Tibia I in the male is armed at distal end with a stout process which 

 is curved and spinulose.

 Barnard. Ship Monsoon. 



Integument of cephalothorax and appendages reddish or chestnut; 

 that of the abdomen brown. Pubescence of the body throughout 

 dense; yellowish brown or light rust colored. 



Cephalothorax low and flat; the pars cephalica not elevated. 

 Fovea thoracica transverse, shorter than the width of the eye-area. 



Eye-area twice as wide as long. Anterior row scarcely longer than 

 the posterior one; strongly procurved in dorsal view. Anterior 

 median eyes distinctly larger than the laterals. Eyes of the second
