Cycloctenus fiuja.r, sp. nov. 



Femina. — -Length, 13mm. ; length of cephalothorax, 5mm. 

 Legs, 4, 1, 2, 3 ; 1, 2, and 3 not difl'ering greatly in length. 



Cephalothorax and abdomen of a brownish-yellow ground- 

 colour, mottled with black or dark-brown, and moderately 

 thickly covered with short appressed reddish hair, the whole 

 superior surface of the body presenting a brilliant brindled 

 appearance. The predominating colour at the sides and in 

 front of the pars cephalica is dark-brown, and between the 

 posterior row of eyes and the anterior extremity of the thoracic 

 fovea brownish-yellow, with flecks of a darker hue. On the 

 lateral slopes of the pars cephalica the dark flecks are some- 

 what wedge-shaped, and lie parallel with the lateral indenta- 

 tions. Sternum and maxillae brown ; falces and labium dark- 

 brown. Legs and palpi of the same ground-colour as the 

 bod}-, flecked and anniilated with brown. On the dorsal 

 surface of the abdomen there is a fairly distinct pattern formed 

 by a brown fleck in the median line near the base, and four 

 others, two on each side — the first pair situated about half-way 

 between the base and the posterior extremity, and connected 

 with the basal fleck by two rather indistinct lines ; the second 

 pair about a millimetre behind the first, and also connected 

 by faint lines. The lines connecting the first pair make a 

 somewhat acute and those connecting the second pair an 

 obtuse angle. Most of the ventral surface between the vulva 

 and the spinners is of a reddish hue, due to the colour of the 

 hair. Vulva reddish- and dark-brown. The dorsal pattern 

 of the abdomen varies a good deal, according to the age of the 

 spider. 



Cephalothorax somewhat longer than the tibia of a leg of 

 the fourth pair, much constricted at the caput, the sides of 

 which are nearly vertical, here about half as wide as at the 

 broadest part of the thorax, which is strongly rounded at the 

 sides, somewhat dome-shaped, as high as or a trifle higher 

 than the caput, and moderately steep; central and lateral 

 indentations all ver>' distinct ; so is tlie junction between the
