hairy hairs posteriorly (fig. 3); moreover quite anteriorly and 

 quite posteriorly a pair of bristles intermediate in length and 

 strength between the minute and the long hairs. — Between 

 the shields a rather wide nnprotected band. Around tlie shields 

 a narrow^ unjirotected margin. 



Ventral side. Tri t o ster n u m (fig. 4) of the usual shape, 

 rather wide, suddenly narrower in its distal third part, 

 where a pair of minute triangular transparent pieces are placed 

 laterally; so too laterally of its distal end. Laciniae lono-, 

 well feathered. Sternal shield rather long, with wavy 

 edges, and with the usual three pair of bristles. Anal 

 shield oval, small, with the usual three hairs, the anus in 

 the middle and the cribrum quite posteriorly. On the venter 

 four pairs of small bristles before the anal shield and one pair 

 flanking it. Stigmata on a level with the centra of the 

 foveolae pédales IV. Peri tre ma short, ru)ining forward 

 and outward, not passing the foveolae IV. 



E p i s t m a (fig. 5 and 6) ratlier short, triangular, with 

 concave sides, and with a long narrow mucro on each side 

 of the more or less wide bottle-shaped end. Sometimes the 

 edges are finely denticulate (fig. 6); sometimes the lateral 

 mucro's may be slightly bifid (fig G) ; sometimes the end is 

 blunt (fig. 6) ; all these I consider as accidental variations. 

 S t y 1 i long (fig. 5). 



M audibles not long, reaching, when wholly retracted 

 the second pair of thick dorsal liristles. Chelae (fig. 7) of 

 the usual shape ; not slender, not robust ; ujîper jaw with 

 til)ial and tarsal sense organ, with two incisors and one canine 

 of about the- same shape. Lower jaw with the sti'ong end- 

 incisor and with 5 teeth increasing in si/e backward and 

 directed backward, following one another regularly, so that it 

 is not easy to discern incisors from canines. P u 1 v i 1 I u m 

 a row of stifi' hairs. 



Maxillae. H y p o s t o m e (tig. 4) wide, with the usual
