marginal spines. Dorsum rather strongly wrinkled, and with a well formed 

 ridge over the stigmatie areas. Integument rather elosely studded with tubular 

 glands or spinnerets (fig. 8«), the orifices of which are circular or cup-shaped ; 

 besides these there are numerous well defined compound groups of spinnerets 

 (fig. 8£), but in these the subcutaneous tubes are very short and suddenly attenu- 

 ated, so that the whole structure appears like a truncated pear in miniature. 

 Marginal spines (fig. 8c) stout, suddenly truncated, the truncated ends being in 

 many instances divided so that they present either a deep cleft or a more or less

jagged appearance. Stigmatie clefts (fig. 8^/) strongly evaginated and thickly 

 set with a series of stout spines varying in number from 9-13; between these 

 and the extreme margin is a group of circular spinnerets. Antennae (fig. 8c) 

 of eight segments, of which the third is much the longest, being almost equal in 

 length to the last four segments together ; the fifth is also unusually long. Legs 

 stout ; tarsi (fig. 8/) very short ; lower digitules broad and spathuliform ; claws 

 very short. Anal lobes (fig. 8//) with four or five long hairs ventrally and two 

 or three distally. Length, 4-6*2 mm. (older examples may be much larger).
