furnished above with short strongish hairs ; the fangs are of a still darker hue 

 than the falces. 



The MaxillcB are strong, straight, enlarged at their extremities, where they 

 are rounded on the outer, and obliquely truncated on the inner-sides, the inner 

 edges curved somewhat over the labium, which is of an oblong form, deeply 

 notched or hollowed out in a circular form at its apex ; these parts, as well as 

 the sternum, which is of ordinary form, are of a dark red-brown coloui', the 

 labium being rather the darkest. The maxillpe are furnished with strong 

 bristly hairs ; those on the inside, and beneath their extremities, forming 

 strong tufts. The labium and sternum are also furnished with hairs, and these 

 are less strong than those on the maxillse. 



The Abdomen is of moderate size and oval form. Its fore part (looked at 

 in profile) is high, and slopes gradually to the hinder extremity ; the upper 

 part and sides are of a dull yellowish colour, marked chiefly on the sides and 

 outer edges of the upper part with black-brown spots and short strise. There 

 is also, on the fore part of the upper-side, an indication, by means of a dark, 

 irregular margin, of a longitudinal central oblong marking, pointed at its 

 liinder extremity, and with an obtusely angular prominence near the middle 

 of each side — the hinder part of this marking is followed by other dark, 

 irregular markings to the spinners. The under-side is sufiused with dull 

 brown, laterally bordered with a yellowish, ill-defined stripe, along which is a 

 row of small, rust-red spots ; there appears to be some variation in the 

 markings on the upper side, one female being far more marked witjj black- 

 brown, and having some oblique pale stripes on the sides. Besides the ordinary 

 spiracular openings, there is, on either side, another narrow, reddish slit, or 

 opening, a little above the usual one when the spider is looked at in profile 

 (f. 3p). Also, between the large spiracular plates or opercula are two other 

 still smaller openings of a reddish hue (f. 2ii), all of which probably open into 

 spiracular tracheae. These openings have been observed also in Argyroneta ; 

 and in the Drassoid genus Anyphmna analogous ones have been found between 

 the ordinary spiracular plates. The spinners are very short ; those of the 

 inferior pair being the strongest, and of a paler hue than those of the superior 

 pair. 



The colours of the female are clearer, and the markings better defined than 

 those of the male above described ; their general character, however, is tolerably 

 similar. The figure given (Z.c. supra) by Dr. L. Koch, of the female, is 

 excellent. I have not been able to learn anything of the habits or economy 

 of this fine and remarkable spider.
