long spines, internally with 7 intermixed with set^ ; tarsus 

 with 3 basal and several apical spines. 



First leg with tibia armed externally with a few spiniform 

 setge ; protarsus armed below with 4 apical and 4 external 

 spines ; second leg with substantially the same spine-armature 

 as the first ; third leg as in the other species, tibia and patella 

 furnished with stout sette above intermixed with spines in 

 front, protarsus with two series of spines above and a few 

 apical spines below, tarsus spiny in front and below ; fourth 

 leg with a few spines amongst the setse at the apex in front, 

 protarsus and tarsus spiny throughout their length below. 

 Legs bent up and not accurately measurable ; the third and 

 fourth stouter than the others, 4, 1, 2, and 6 apparently 

 subequal in length. 



Measurement iyi millimetres. — Total length (including man- 

 dible) 21 ; length of carapace 9, width ^'fi^ width of head 6, 

 of mandibles at base 5"5. 



Loc. Lawlers, East Murchison Goldfields, West Australia. 

 A single female example sent to the British Museum by 

 ]\Ir. W. 0. Manstridge, after whom I have great pleasure in 

 naming this interesting new form. 



To recapitulate : the females of the genera here con- 

 sidered have the following characters in common : — The 

 carapace is considerably longer than wide, nearly smooth, 

 with procurved fovea and elevated head. The anterior 

 lateral eyes are well in advance of the others and are situated 

 either close together or some distance apart upon the anterior 

 border of the carapace ; the mandibles are armed with a 

 strong rastellum, consisting of strong short spines and a 

 spinous process on the apical internal angle, and below with 

 two rows of larger teeth as well as some smaller ones that 

 constitute a shorter third intermediate row. 



The tarsus of the palpi and the tarsi and protarsi of the 

 first and second legs are scopulate and weakly spined, there 

 being no lateral rows of spines such as are characteristic of 

 the Idiopese and Pachylomereaj. The claws of all the legs 

 are armed basally with one or two long teeth and one or two 

 minute ones. 



The sternum is longer than wide, with three distinct pairs 

 of sigillae, excluding tiie pair that embraces the labium. 

 Labium short and broad, not spinous, depressed between the 

 maxillee. 



The genera, each of which, so far as at present known, has 

 but a single species, may be recognized by the following 

 table : —
