into a lake-coloured process of somewhat uniform breadth^ 

 curved upwards and backwards. Genital bulb represents, 

 principally a series of membranous folds and processes, which 

 have yellowish and brownish-yellow tints ; bulb viewed from 

 outer sides exhibits a conoid outline, projects at nearly a 

 right-angle to lamina, occupies about one-half its length ; 

 consists of four folds, the upper or basal fold is produced 

 into a triangular enlargement in front, second projects only 

 slightly beyond the first, third and fourth of nearly equal 

 width, together perceptibly narrower than upper fold; the 

 fore-extension of terminal fold differs from that of basal 

 membrane inasmuch as the apex of it is drawn out and 

 curved backwards. Two strong apophyses occur beneath 

 lamina, springing from base of bulbus, botli membranous,, 

 wide, tapering, inner shortest, dark, spiral ; crossed outwardly 

 by the larger and pale apophysis, whose apex reaches nearly 

 to extremity of clava. A third apophysis, which has a yel- 

 lowish colour, springs from near centre of inner side, base 

 stout, tapers rapidly from first third into a thin flexible 

 bristle, spiral (plane), curved backwards. 



Abdomen elongate-oviform ; in colour light-fuscous, flecked 

 with spots of a paler tone ; folium ovate, covers most of 

 dorsum, approximates to olive-brown, lake-stains ; edge wide, 

 olive-green, undulating, partially encloses on fore-half an 

 ovate space ; exhibits on posterior half a series of tooth-like 

 dilatations projecting inwards. Inferior half of lateral mar- 

 gins mottled with dark-brown. 



Single example, Potcell collection. 



Linyphia decolora, sp. nov. 



Fcm. — Ceph.-th, long, 2; wide, 1-2. Abd., long, 3; wide, 

 2-5. First and fourth pairs of legs about equal, 5-5. Second 

 pair, 4-4, slightly exceeds third. 



Ceplialotliorax amber-colour, stained with lake and olive- 

 green ; almost glabrous. Cephalic part roundly truncated, 

 facial index sensibly shorter than lateral ; height of clypeus 

 nearly equal to one-half the depth of facial space ; thoracic 

 indentation longitudinal, deep ; radial and caput striae well 

 defined ; profile-contour rises from the petiolum at an angle of 

 45 degrees; runs with a perceptible incline to centre of occiput, 

 from thence dips more abruptly to frontal margin. 



Eyes of fair size, seated on fuscous spots ; posterior row 

 procurved, intervals separating middle pair from each other 

 and laterals are about equal to eye's radius and diameter 

 respectively ; anterior row recurved, median pair much the 

 smallest of eight, one-fourth of an eye's breadth apart, re- 

 moved from side-eyes by a space fully equalling their own 

 diameter; laterals have the opalescence of hind-centrals, exceed
