tibial branch ; no trace of it is found in .1. ft/u'riJijei (PI. xv., 

 fig. 21). As moreover the tibial branch assumes in tliis species 

 a sliape not met with in the otlier members of the genus 

 AnstraliofyOiiia (being widened and hollowed proximall}' so as 

 to shelter the base of the seminal bi'anch), it has been found 

 necessary to isolate same and to erect a special sub-generic 

 division for its leception. 



The genus Aiistriiliii!<(iiiii> will, theiefore, be divided into two 

 sub-genei-a : — 



1. AusTRALlosOMA (aeii.^11 strictu), the gonopods of which are 



split into three branches. 



2. DiCLADOSOMA, the gonopods of which are split into two 



bi'anches, the other generic characters remaining 

 identical in both divisions. 



Amongst the known continental Anst niliosmiut, a species has 

 been mentioned above, which has been ascribed by its autlu)i' 

 to tlie genus Ijiidi-DiniiihiKOhia : — E. hlfuJi-afiuji, Silvestri, 1898, 

 from Cairns, Queensland. It has not been found convenient 

 to use this genei'ic name for the continental foi-ms hereafter 

 described, as: — 1st, no full description has been given of the 

 genus, and 2nd, while as much as can be understood from Prof. 

 Silvestri's writings, the continental Ai(nfr(ili<isoni<i seem differ- 

 ent from the New Guinea ty])e specimen of E/isfroiHjiiJn.-inDia, 

 E. fiisn'dtinii, Silv., 1894. 



The mime Fjimi i-oikjijIohouhi was created by Vvoi. 

 Silvestri^-* in 1896. No description was given, as already 

 stated ; but, the genus being included in an analytical key of 

 his PolydesmidjT?,^o \^, may be inferi'ed, from the terms of the 

 key, that its characters are the following: — 



Pores opening sideways in the keels of the segments 5, 7, 9, 

 10, 12, 13, 15 to '19. 



Keels small, linear, with posterior angle no< pioduced : keels 

 of second segment pi-oduced below the level of the keels 

 of segments 1 and 3.

"^ It is to be observed that Silxcstri's f:imily h\ no inc:ins answers 

 the likewise named division of other authois.
