meutiouuil l)y the said authors, S. rii/irijic!^, the seiuiiial duct of 

 the posterior gonopds is said to end in a pseudo-flag'ellum, 

 which is Avaiiting in S. vari'sl, tl)e type specimen. Moreover, 

 it is still uncertain it' the cliai-acters chosen to distinLTuish the 

 said genus are of positive generic value. Nevertheless, it 

 seems highly prohable that the known Australian 'i'l-igoniulids 

 have to be isolated from 7V/;/^;^'/^//^^• in a distinct genus, the 

 characters of which have still to be tested.

 one segment apodous ; 105 pair of legs. 



Two specimens from Condamine, Queensland. 



Colour, a dark blackish-brown ; the anterior part of pro- 

 zonite (as far as exposed when the animal is curled up) ochre- 

 yellow ; the posterior margin-orange red. Legs and antennse 

 orange-yellow. 



Head, smooth and shining, leathery along the posterior 

 niargi]). Labral dimples four. Median sulcus thin in front, 

 faint backwards, obsolete between the antennae. Eyes rounded, 

 divided by a space not twice the diameter of an eye; ocelli 

 small, flattened yet distinct, arranged in seven to eight more 

 or less curved series, from 5, 7, 8, 7, 6, 5, 2 = 40 to 8, 8, 8, 7, 

 6, 5, 3 = 45. Antennae short, scarcely reaching beyond the 

 middle of the 6rst segments. The four proximal joints almost 

 naked ; fifth with but few distal setae ; sixth more pilose ; last
