(PI. xxiii., tigs. 99, 100 and 101.) 



9. Cephalothorax, 102 mm. loiif^, 78 mm. broad ; abdomen 10'4 

 mm. long, 6"7 mm. broad. 



Cephalothorax. — Elongate, obovate, yellow, sparingly clothed with 

 very fine, pale yellowish hairs. Furs ceplndlcu ascending, moderately high, 

 truncated in front, segmental groove distinct ; ocular area broader than 

 long, raised, nearly black at summit; cli/petis hyaline, moderately broad, 

 steep, slightly excavated at middle. I'ars thoracica retreating, posterior 

 angle indented, radial grooves distinct ; thoracic fovea deep, procurved ; 

 marginal band fringed with fine hairs. Eyes. — Distributed over two rows 

 of four each ; front row procurved, the rear recurved ; anterior and rear 

 side eyes largest of the group, of equal size, elliptical, and poised obliquely ; 

 anterior medians round, separated from each other by a space equal to 

 once their own individual diameter, and each again from its lateral neigh- 

 bour by about one-half that space ; rear laterals widely removed, elliptical, 

 each slightly smaller than its lateral neighbour which it touches (Pi. xxiii., 

 fig. 99). Legs. — Concolorous with cephalothorax, moderately long, 

 tapering, hairy, but displaying naked areas; each armed with moderately 

 long spines; metatarsi and tarsi i. and ii. partially scopulated. Falpi. — 

 Moderately long, similar in colour, clothing and armature to legs ; tarsi 

 scopulated. Falces. — Dark brown, projecting, clothed with fine hairs and 

 long, coarse bristles ; inner margin of the furrow of each falx armed with 

 a row of ten strong teeth ; famj dark brown, shining, well curved. Max- 

 illcv. — Arched, hairy, yellow, inner angle cream-yellow, and fringed with 

 a reddish beard, heel well rounded ; at the excavated angle above the 

 latter there is a cluster of small spines. Labium. — Similar in colour and 

 clothing to the maxillae, submerged, short, broader than long; near the 

 apex, which is slightly excavated, there are three small spines. Sternum. 

 — Elongate, somewhat shield-shaped, yellow, ai-clied, clothed with bristly 

 hairs, and terminating just between fourth pair of coxae in an obtuse 

 point ; sigilla marginal. Abdomen. — Obovate, arched, slightly overhanging 

 base of cephalothorax, clothed with fine, short hairs; superior surface 

 yellow with chocolate brown spots and median and lateral markings, the 

 latter broken and forming a rather prominent, though undefined pattern 

 (Pi. xxiii., fig. 101) ; sides yellow with chocolate brown spots ; inferior 

 surface ochreous yellow with a few chocolate brown spots and concolorous 

 median and lateral markings; pulmonary sacs yellow; chitinous plate 

 immediately in front of riina epigasteris shining, yellow, hairy, uneven, 

 strongly arched at middle and compressed latei'ally. Spinnerets. — Yellow, 

 hairy ; superior pair tapering ; first and third joints of equal length, 

 second joint shortest ; inferior spinners short, narrowest at the base, and 

 separated from each other by a space eqnal to once their individual 

 transverse diameter. 



Obs. — This species presents another instance in which ocular mal- 

 formation occurs and again, as in the case of A. hirsnta (ante, p. 142), the 

 right side is affected, but in an example now under study, the rear laterals
