Adult male. Length, 1-tenth of an inch. Length of cephalothorax, 

 - 1-twentieth. Breadth, 1-twenty-fourth. Relative length of legs, 

 1, 2, 4, 3. 



Cephalothorax very convex and elevated in front, slightly depressed 

 from the highest point to the eyes, much depressed behind and 

 also on the sides, where some furrows converge towards the 

 middle. Colour dark brown, tinged with red, darkest behind 

 the elevated part, which, with the frontal margin, is clothed with 

 coarse white hairs. 



Eyes nearly equal in size, fhe four middle ones form a square, 

 and those of each side pair are placed obliquely on a small 

 tubercle. 



Legs moderately stout and furnished with hairs. Relative length, 

 1, 2, 4, 8. The fourth pair has a calamistrum (or combing appa- 

 ratus) on the upper side of their metatarsi, a peculiarity on which 

 Mr. Blackwall has founded the family j^iniflonidse. Each tarsus 

 ends with three claws; the two upper ones curved and pectin- 

 ated and the lower one inflected near its base. The colour of 

 the legs is a pale yellow-brown. 



Palpi short and strong, of the same colour as the legs. Humeral 

 joint gouty at the end on the outer side. Cubital joint strong, 

 convex on its upper surface and strongly curved inwards. Radial 

 joint longer than the cubital and has two projections, one (which 

 is a leading characteristic of the species) in the form of a long 

 stoutish, pointed spur, tipped with dark brown, springing at right 

 angles from the upper side of its extremity ; the other, an obtuse 

 rounded one, is at the extremity on the outer side. The digital 

 joint is dark brown, pointed at the end. Palpal organs highly 

 developed, with a strong process curved from their extremity 

 round the outer side, and ending in a kind of twisted or spiral 

 point, which reaches to the articulation of the radial with the 

 cubital joint. 



•Falces yellow-brown, long, with a large prominence on the under 

 side and a minute one at their base in front towards the outer 

 side ; they are curved a little forwards at the ends and hollowed 

 out about the middle of their inner surface, leaving the ends very 

 prominent. 



Maxillae similar in colour to the falces, convex at the base, rounded 

 at the ends, which are more abruptly curved on the inner than 

 on the outer side. They are inclined towards the labium.
