less straight inner margin, but with a well-marked shoulder on the outer, in the 

 case of the third pair a second notch observable ; beyond the last pair of lobes 

 the margin produced into 5 or more sharp conical projections each minutely 

 serrated on the outer border, these projections gradually diminishing in size 

 anteriorly ; the usual number of squamae in the intervals between the lobes, 

 3 or 4 between the third pair and the first marginal projection ; a very strong 

 paraphysis arises from the inner margin of each lobe, another about half the 

 size from the outer margin, and another of intermediate length from the middle

of the second interval ; marginal area beyond the last pair of lobes strongly 

 chitinised and cristate. Perivulvar pores in four groups, 12 to 13 in the anterior 

 and 8 to 9 in the posterior ; 4 transverse calli on the anterior part of the pygidium, 

 the median pair more or less united ; two single series of pores arising from the 

 interval between the second and third lobes and between the third and the first 

 marginal projection ; filiform spinnerets numerous ; anal orifice near the middle 

 of the pygidium. Length 2 mm. ; breadth 1-5 to 2 mm.
