five — arcuate lines of similar colour ; flecks on lateral margins 

 I inconspicuous, approximate to ground colour ; ventral shield 



olive brown; branchial opercula chrome-yellow. Vulva orange 

 brown ; transverse, oval area, occupied by two deep, circular 

 fovese, intersected by a dark bordered, broad septum, their 

 equal in breadth, laterally prolonged above the rima genitalis, 

 extremities acute, revolute.

Gen. Cblabnia, Thor. 



Gelaenia voraginosa, sp. nov. Plate Pig. 5. 



Femina. — Ceph. th., long, 5'2, broad, 6. Abd., long., 10 ; 

 broad, 14; deep, 11. Legs, 1—2, 4, 3 = 21-2, 12, 10 mm. 



Cephalothorax deep fulvus, olive tinge, passing into coffee- 

 brown on lateral margins, furnished with numerous papillae 

 — mostly in rows, projecting, short, stout, black bristles ; 

 somewhat reniform, narrowly constricted at caput, pars 

 cephalica, rather depressed, sides abrupt, mamiform eminences 

 well-developed ; prolonged somewhat upwards into a stout 

 sub-conical projection, nearly as long as wide at 

 base, occupying greater part of frontal space ; clypeus 

 retreating, depth perceptibly exceeds interval between a fore- 

 centre eye and the lateral next to it ; pars thoracica — viewed 

 laterally, obtuse-conoid ; series of six indentations occur at 

 edge of posterior inclination, centre pair divided by the 

 bisected fovea; radial stria? somewhat deep and short; caput 

 grooves faint forwards, form strong, angular depressions at 

 limit ; profile-line rises at an angle of SOdeg. from thoracic 

 junction, dips forwards at a rather stronger inclination to 

 mamiform elevation — which represents an obtuse-conoid 

 projection, bends slightly upwards to posterior row of eyes. 



Eyes tolerably small ; posterior row recurved, line through 

 centrals strikes fore-edge of anterior laterals, front row more 

 strongly recurved ; fore-central eyes posited on prominence, 

 form a nearly quadrilateral figure, enclosing conical apex, front 

 line rather shorter than hind, visibly surpasses sides; posterior 

 pair one-third smaller than fore-centrals, placed on slight 

 discoid elevations ; anterior pair little more distant from side 

 eyes than are the hind-centrals, a space about equal to the 

 interval between one another ; la.terals scarcely equal to hind 

 centrals in size, seated obliquely on a strong prominence 

 nearly contiguous. 



Legs creamy-yellow, second half — rather less — of femoral 

 joints coffee-brown, stains on first half ; patella? and annula- 

 tions normal brown ; tibiae have three wide rings ; metatarsi 

 three less defined annuli ; tarsi suffused ; annulations on 

 tibial and metatarsal joints of two posterior pairs somewhat 

 obliterated ; I. and II., III. and IV. of about equal strength ;
