Talitridae from Victoria. 33 



Antennae agreeinfr essentially with the previous species in 

 relative len<_^th and form. 



Buccal area. — The anterior and posterior lips, and first and 

 second maxillae, agree precisely with the former species, the 

 mandibles only differ slightly in the teeth of the cutting edges. 

 The maxillipeds have the ultimate joint (dactylus) of the palp 

 coalescent with the penultimate one (propodus), and terminates 

 in a minute conical piece (the remnant of the dactylus), pos- 

 sessing one or two spinules, and at the apex a long single 

 spinule. Except for this difference the palp agrees closely with 

 T. sylvaticus. The inner masticatory plate quite agrees with 

 that species, and the outer plate also agrees in form, except 

 that the apex is rather broader, distinctly indented, and clothed 

 with tw^o tufts of setae, separated by the indentation. 



GnatJiopoda. — The first pair has the carpus widely expanded 

 distally, being fully three-quarters as wide as its length, and 

 is minutely but distinctly lobed. The second pair is without 

 any special characteristic, and quite normal to the genus. Like 

 the previous species, there are very large branchiae attached. 



Pereiopoda. — These are rather more spinulose than T. sylva- 

 ticu-?, and possess rather smaller branchiae. Tlie incubatory 

 lamellae are similar, and in all other respects are in close agree- 

 ment, 



Pleopucla. — These are quite rudimentary, nmcli more so than 

 in the preceding species. The first pair has a stout peduncle, 

 with a single minute outer ramus articulated to the stem subapi- 

 cally. Beyond the articulation of this ramus the peduncle is 

 produced a little at the apex, evidently the vestige of the inner 

 ramus, but it is quite coalescent with the stem. The second 

 pair exist only as a minute cylindrical process, being but a 

 vestige of a former peduncle. Each pair possess a few little 

 setules, but no feathered setae. 



Uropoda. — These agree in form and armature with the pre- 

 ceding species, but are relatively rather shorter and stouter. 



Telson. — Quite similar to the preceding species. 



Sexes. — There is no apparent sexual differentiation. 



Colour. — Varying from reddish-brown to black, and some- 

 times pale yellow.
