and furnished with hairs and a few fine bristles) being a 

 little lighter in hue, while the falces, maxilla?, labium, and 

 sternum are darker. The falces are long, powerful, verti- 

 cal, and prominent near their base in front, being also armed 

 with a row of five strongish teeth on the inner side of the 

 extremity of each falx. 



The eyes are in the ordinary position and placed on dark 

 tubercles ; they are rather small, and do not differ very greatly 

 in size. Those of the hind-central pair are much nearer to each 

 other than each is to the hind-lateral eye on its side, the interval 

 between them being equal to a little more than an eye's diame- 

 ter; those of the fore-central pair are almost contiguous to each 

 other. The clypeus projects evenly forwards ; and its height 

 rather exceeds half that of the facial space. 



The palpi are tolerably long, similar in colour to the legs ; 

 the radial and digital joints are of a deeper tinge, and devoid 

 of any terminal claw. 



The abdomen is of an oblong, somewhat cylindric-ovate 

 form, rather broadest at its hinder extremity ; its colour is 

 black; and it is thinly clothed with hairs. The genital aperture 

 is large, prominent, of characteristic form, and of a dark 

 blackish and red-brown colour. 



A damaged example of the male appeared to show but little 

 difference from the female in general character and appear- 

 ance. The falces, however, are less powerful ; and the abdo- 

 men is shorter and less cylindric in form. The palpi have the 

 cubital and radial joints short; the latter is considerably pro- 

 duced at its fore extremity on the upperside, the termination 

 being obtusely pointed and directed slightly outwards ; and 

 on the outer margin of the radial joint is a rather dense tuft of 

 strong black hairs. The digital joint is large and of a short 

 roundish-oval form ; the palpal organs are prominent and 

 complex ; near their extremity, on the inner side, is a strong, 

 tapering, sharp-pointed, black spine, which curves round in a 

 nearly circular form underneath the fore extremity of the digital 

 joint, and has its hair-like point in contact with the outer side 

 of the palpal organs, at whose extremity there are also several 

 other prominent corneous processes and spines. At the base of 

 the palpal organs, on the outer side, is a strong curved process, 

 somewhat obscured by the tuft of hairs on the outside of the 

 radial joint. 



Examples of this spider, which I believe to be hitherto 

 undescribed, were contained in a collection made by Mr. H. 

 C. Young of Glasgow, near that city, and kindly sent to me 

 for determination.
