area comparatively smooth, with distinct lines radiating from the central 

 nucleus, the larger ones being widely separated and equidistant. Besides 

 these there are also some faint concentric ones visible in some of the examples. 

 Lateral plates narrowly rectangular, length much greater than width, outer 

 angles produced and darker than the rest ; caudal process triangular, with 

 the angles^ rounded ; anal valves nude, minute, and only visible under a 

 rather strong magnification. 



Length 6-0*25 mm. ; width 5-5-25 mm.

bilateral and one cephalic, broad, flat and faintly bituberculate projections ; 

 the tubercles widely separated and somewhat inconstant in size, some being 

 faintly indicated, others very pronounced ; caudal process short, width at 

 base slightly greater than the length, apex suddenly attenuated. Derm thin 

 and transparent, and of a pale horn-colour ; tubercles and caudal process 

 darker. Antennse (fig. 5, B) of seven segments ; third and fourth equal 

 in length and longest ; the last three segments with long slender spines. 

 Stigmatic clefts very small and shallow ; spines small and conical, about 

 27 in number ; immediately within these is a large and very compact group 

 of circular spinnerets numbering from 90-100 in all ; these organs are
