52 ON SOME RARE ARACHNIDS 



The CLYPEUS is extremely narrow. It is in fact narrower 

 than each anterior eye. 



The FALCES are rather weak, the proximal joint is somewhat 

 conical, being much narrower at the apex than at the base. 

 The distal joint is long and slender. 



The STERNUM is broadly heart-shaped, of a clear yellow- 

 brown colour, and besprinkled with long hairs. It is not, or 

 only very slightly, provided with bays corresponding to the 

 coxae of the walking legs. 



The LABIUM is of the same colour. It is short and almost 

 square, with its anterior border rather concave. 



The MAXILLAE differ very much in the two sexes. In the 

 female each is of the same colour as the sternum and labium. 

 Each is strongly inclined to the lip, with an almost squarely- 

 cut anterior border, and with a broad, rounded-ofif, antero- 

 internal angle. In the male, however, this angle is drawn 

 out into a fine point, and the anterior border presents in 

 addition a rounded tuberculiform process. The internal 

 border is thickened and of a dark colour. Owing to this 

 tapering of the antero-internal angle the rostrum is distinctly 

 visible rising above the labium. 



In connexion with the latter organ, I was quite unable to 

 see any lateral processes springing from it and separating the 

 maxillas from the sternum as described by M. Simon* in an 

 allied species. 



The PALPI of the female are simple; the tarsus is longer 

 than the tibia and patella together. It is acuminate, very 

 hairy, and bears no terminal claw. The palpi of the male are 

 very curious. They are dark brown, nearly black, in colour, 

 and are carried bent outwards in a very remarkable manner 

 as shewn in figure 13. The femur, tibia, and patella are 

 short, broad, and almost similar. There is a little variation in 

 different individuals, but in figure 13 the femur and patella 

 are probably shown a trifle too long. The tarsus is slightly
