128 RKCORHR OP THE AUSTRAIJAN Ml'SKl'M. 



Pi'of. Silvestri states that his type possess scobiiias from the 

 ninth to the ])enaltiniate, whicli does not agree with the three 

 specimens examined, and that the metazonites are smooth, no 

 mention being made ot" punctures Moreover, slight differences 

 can be found between Prof. Silvestri's figures of the copulatory 

 appendages and ours; tlie sides of the ventral plate of anteinov 

 gonopods are less angularly excised, the apex is more pointed; 

 the distal, lamellar end of the outer branch of posterior gono- 

 pods is somewhat differently shaped. There is, therefore, 

 hardl}' any doubt that the Grayndah specimens belong at least 

 to a sub-species different from the Cairns form. 



DiXRMATOciucrs (? Cladiscocricus) C'ONSIMilis, s/j. nor. 

 (Plate xvi., fig. 45). 

 9 mat. : length 62 m/in : diameter 8 m/m ; 52 segments ; 

 one segment apodoiis ; 97 pair of legs. 



The only specimen to hand so closely resembles the females 

 of D. falcidiis, that it has been deemed sufficient to note the 

 differences. No iniportamre can be given to the colour and to 

 the length recorded as the animal is contracted having only 

 recently cast its skin when captured, as is evident by the fact 

 that the integuments are still soft. 



The anterior margin of first segment is slightly emarginate 

 on a. level with the eyes, and not as bi'oadly rounde«:l. The 

 scobinas are entirely different from those of J), fulnitits ; the 

 dimples assume the shape of a deej) transverse sulcus, and the 

 s{)ace between them is hardly equal to the breadth of one of 

 them. The posterior sulcate field is indistinct as the sulci are 

 continued by the concentric stria" of the suri'ounding integu- 

 ments (11th segment). Or else the dimples ai'e more crescen- 

 tic, the distance between them is equal to about one-and-a-half 

 diajneter of one of them, and the sti-iate field is distinct (PI. 

 xvi., fig. 45, 21st segment). 



TMie exposed postei'ior halt' of the pro/.onites cannot be 

 described as punctui-ed ; oi' rathei' Ihe punctures are strongly 

 intermingled with stria*. The spofs, fhe jioj-es are pierced in, 

 appear somewhat raised. The postcrioi' nnirgin of the last 

 segment is angularly jiT'oduced, but cut at right angles and not 

 emarginate on each side of the apex, m> that no distinct pi-ocess 

 is to be seen.
