scarcely that interval from anterior pair, which are visibly 

 more than an eye's breadth and a half from one another ; 

 lateral eyes perceptibly smaller than centrals, seated 

 obliquely, their radius apart, on a stout tubercular eminence. 



Legs reddish - mahogany colour (brown - mahogany in 

 second example) ; hairs black, few fine bristles ; 1-2 of 

 netirly equal length and strength ; 4 exceeds 3 in length 

 and somewhat in stoutness ; superior tarsal claws — 1st pair, 

 moderately curved (apparently), 8 rather strong, open 

 teeth ; inferior claw long, bent, teeth (?) ; auxiliary claws. 



Palpi tolerably slender, colour and armature of legs ; 

 palpal claw slightly curved, 7 open teeth, centrals longest. 



Falces dull-black, lake tinge ; stout, somewhat pyriform, 

 directed moderately forwards, nearly equal in length radial 

 and digital joints of palpus ; double row of strong teeth, 

 outer row 7. 



ALaxillce stout, about as broad as long, somewhat semi- 

 circular, base constricted, slightly inclined towards labium, 

 which is about as long as broad, somewhat conical, everted, 

 rather more than one-half length of maxillae; base of 

 organs chocolate-brown, margins olive tinted yellow-brown. 



Sternum elongate-cordate, well-defined eminences oppo- 

 site coxae, base tapers off to a tail-like point from posterior 

 pair; brownish-black; large, circular, brownish-yellow spot 

 between anterior pair of eminences. 



Abdomen light-yellowish stone-cclour, area enclosed by 

 sigilla, from first pair slightly suffused with a dull olive- 

 green (less defined in second example) ; fore and hind margins 

 have a pale-olive hue, sparsely clouded with streaks of lake ; 

 lateral extremities, fore-spine, and base of hind-spine, black ; 

 fore-part of latter spine red-lake, apex dark ; posterior spine- 

 like tubercles lake-black ; sigilla black, tinted more or less 

 with brown-lake ; centre and extremities of ventral surface 

 greenish-black, intermediate longitudinal bauds, which equal 

 central in breadth, have a yellowish hue, suffused with lake ; 

 irregularly-shaped yellowish-coloured spots, base of two largest 

 partially encircle spinners, tapering off round posterior mar- 

 gins of branchial opercula ; few short black hairs on margins 

 and posterior tubercles ; horny ; rather more than twice as 

 broad as long, aplanate, lateral wing-like projections rise to 

 an angle of 25°, terminate with stout spines directed out- 

 wards; anterior pair 1mm. in length, inclined slightly forwards ; 

 posterior pair, 4mm., curve moderately backwards; viewed 

 from above, profile-contour of central third represents a visibly- 

 depressed segment of a circle projecting over base of cephalo- 

 thorax ; extremities of line slope perceptibly backwards to 

 anterior spines ; from apex of posterior spines to base of 

 tubercles profile-line forms a slight and even concavity ; tuber-
