9. Cephalotliorax, 2'2 mm. long, 1*5 mm. broad; 

 abdomen, 2'3 mm. long, 1'5 mm. broad (fig. 23). 



C ephalothorax ovate, elongate. Pars cephalica golden- 

 yellow, flat, slightly inclined, sides steep, pubescent, with fine 

 hoary hairs, interspersed by stiff black hair ; ocular area longer 

 than broad, eyes ringed with black; cli/peus not deep. Pars 

 thoracica arched, bright yellow, pubescent, clothed with hoary 

 hairs interspersed with stiff black hairs, retreating laterally 

 and sloping posteriorly ; marginal hand yellow. Eyes in three 

 rows of 4, 2, 2 ; front row recurved, median pair of this row 

 larger than their lateral neighbours ; those of the second row 

 minute, and seated near to their anterior lateral neighbours; 

 rear pair of eyes slightly larger than the anterior laterals. 

 Lef/s yellovv ; first pair exceedingly robust; hairy, and armed 

 wuth spines, those on the first pair being much the strongest. 

 Relative lengths, 1, 4, 2, 3. In the type, which is mature, 

 only one leg, and that of the first pair, is present, all the others 

 having been broken off and lost ; but in an immature form the 

 ambulatory limbs are intact. I^aljn short, similar in colour 

 and armature to legs. Falces yellow, arched, coniform, hairy, 

 Ma.iiUae and Jahium yellow, normal. Sternum elongate, 

 arched, obtusely acuminate and attenuated in front, 

 moderately hairy. Ahdo7nen ovate, arched, slightly overhang- 

 ing base of cephalothorax, hairy ; superior surface and sides 

 yellow, with dark median and lateral markings ; inferior 

 surface has a broad, median yellow band, transversely striated, 

 and relieved by pale-yellow spots between striations ; this band 

 extends from the ri??ia epigasteris to the spinnerets; laterally 

 the abdomen (ventral surface) is white and reticulated by dark 

 yellow markings. Epigynwm transverse, broader than long, 

 situated on a dark-yellow field : it is bisected, and each half 

 presents an appearance suggestive of a square, at the outer 

 extremity of the lower arm of each of which there is a large 

 oval depression (fig. 24). 



S . An immature example of this sex is also included in 

 the collection, and bears the same locality and date as that of 

 the two females. It agrees in colour and clothing to the form 

 described above, and is also very similar in abdominal orna- 

 mentation. As the palpal organs are not uncovered further 

 description is unnecessary. 



//r/7j.— Flat Rock Hole, Musgrave Ranges, July 23, 1914. 

 One mature female (damaged) and one immature female 

 (intact), together with an immature male example, all from 

 isame locality and collected on the same date.
