stripe, pointed at each end, and its edges dark red-brown ; the sides 

 are rugulose, pale chocolate-brown, spotted with whitish and dark 

 red-brown ; the underside also is chocolate-brown, mottled finely 

 with a deeper hue ; the spinners are surrounded by a broken white 

 line. 



A female (v#nch I feel no doubt is of this species) was of a gene- 

 rally paler and more ashy hue, but otherwise resembled it in form 

 and markings. 



Although so exceedingly closely allied to A', crlstatus and X. audax, 

 I have no doubt that the present is a perfectly distinct species, 

 and that collectors will have but little difficulty in distinguishing it 

 by its general appearance, apart from the special differences of the 

 structure of the male palpi. 



The examples above described were found on low plants near 

 Alexandria. 



Xysticus ferus, sp. n. 



Adult female, length 3g lines. 



This fine but plainly-coloured Spider is allied to X. bifasciatus, 

 C. Koch ; its general form and structure are of the normal type. 

 The cephalothorax is of an orange-yellow-brown colour veined and 

 marked with red-brown, especially on the hinder slope ; the ocular 

 region and the middle of the clypeus whitish yellow ; the normal 

 spade-shaped marking, behind the eyes, is scarcely defined by an 

 obscure yellow marginal line, its hinder extremity, however, being 

 more apparent and of a whitish-yellow colour ; from between the two 

 hind central eyes to the beginning of the hinder slope, two parallel 

 red-brown lines, close together, divide the caput longitudinally ; the 

 surface of the cephalothorax is thinly furnished with bristly hairs. 



The eyes are in the ordinary position, and unequal in size, the 

 fore laterals considerably the largest ; those of the hind central pair 

 are slightly larger, and nearer together than those of the fore central 

 pair, the latter being further from each other than each is from the 

 fore lateral on its side ; while the eyes of the hind central pair are 

 much nearer to each other than each is to the hind lateral on its 

 side ; the height of the clypeus is less than half that of the facial 

 space. 



The legs are not very long, but strong ; they are yellow, marbled 

 underneath, particularly the femora of the first and second pairs, 

 with white, and furnished with hairs, bristles, and spines, the latter 

 disposed in the usual way. 



The falces are rather short, strong, but conical, similar in colour 

 to the cephalothorax, with the anterior portion washed with yellowish 

 white, and the front surface armed with strong black bristles. 



The palpi are similar to the legs in colour, and furnished with 

 bristles and spines. 



The maxillae and labium are of normal form, and, with the sternum, 

 similar to the legs in colour ; the sternum, however, is obscurely 

 marbled with yellowish white. 



The abdomen is oval, blunt, pointed behind and roundly truncated
