8590 Arachnida. 



Cephalothorax broad, obtuse, prominent, obliquely and abruptly- 

 truncated in front, thus giving the appearance of two frontal 

 margins, a little way behind the upper one of which is a strong, 

 abrupt, perpendicular eminence, hood-shaped, i. e., convex be- 

 hind and sloping forwards, but flattish in front when looked at 

 in profile : when looked at in front, or full-face, the summit of 

 the eminence is circular, much broader than at the base, 

 and divided longitudinally inlo two segments. There is a 

 deepish transverse indentation behind each side pair of eyes, 

 one at the base of the eminence, and a longitudinal one in the 

 medial line of the hinder part. Colour dark black-brown and 

 shining. 



Eyes in four pairs ; one pair on the top of the eminence towards its 

 frontal margin, and three pairs in a straight line, just below the 

 upper frontal margin of the cephalothorax. The eyes of the 

 side pairs are slightly obliquely placed, and those of the central 

 pair are close together and the smallest of the eight: the other 

 six do not differ much in size. Between the eyes at the top of 

 the eminence there are some strong black bristly hairs, directed 

 forwards, and meeting others which spring from the middle 

 frontal margin. 



Legs of moderate length and strength. Fourth pair slightly the 

 longest ; first and second pairs nearly equal, and the third 

 pair shortest. Their colour is a bright yellow, tinged with 

 orange. 



Falces long, strong and very convex. In colour rather paler than 

 the cephalothorax. 



Maxillae similar in colour to the falces, moderately long and strong, 

 and much inclined towards the labium, which is broad, short 

 and semicircular. 



Sternum very convex, black and shining. 



Palpi of moderate length, and similar in colour to the legs. Humeral 

 joint curved inwards. Cubital joint much longer than the radial, 

 and slightly clavate. Radial joint short, and with two pro- 

 jections — one, on the outer side, is broad, obtuse and concave, 

 with a red-brown corneous process issuing from its concavity ; 

 the other, on the inner side rather towards the front, is slighter, 

 but longer, than that on the outer side, and is bifid at its extre- 

 mity. Digital joint large, broad at its base, gradually lessening 

 to the extremity, and is suffused with brownish black. Palpal 

 organs not very prominent nor complicated ; they consist of
