32 0. A. Sayct: 



one (endopod), which is of equal length to the peduncle, 

 and each is fringed with long feathered setae. Second pair con- 

 siderably shorter than the first, but of similar form and cloth- 

 ing. No vestige of a third pair is to be found. 



Uropoda. — In the first and second pairs the peduncle extends 

 at least as far as the end of the telson, the third pair, two 

 jointed, minute, and of normal form. 



Telson. — Broad at the base, and curving to a narrowly 

 truncated tij), margin entire, and the surface bearing a few 

 little setae. 



Sexes. — No apparent sexual difference. 



Colour when alive variable, usually dark brown, but some- 

 times reddish-brown, and occasionally pale yellow. 



Length. — The largest specimen measured from front of head to 

 telson, 12 mm., but in most of the gatherings they measured 

 about 8 mm. 



Occurrence. — Very common throughout Victoria at all eleva- 

 tions, under logs and dead leaves in forest and scrub lands, 

 preferably in damp situations, but also frequently in dry places, 

 and often in association with the following species. I have also 

 found them just above the tide-level at several places on our 

 coast, under dead seaweed, lying on sand. 



Di>itrihution. — Very common in Tasmania, and relatively in 

 fewer numbers along the coastal and mountainous regions of 

 New South Wales. 



Talitrus kershawi, n. sp. 



(Plate XII.) 



Body rather stouter and usually of a larger size than the 

 preceding species. Cephalon scarcely longer than the first seg- 

 ment of the mesosome. First pair of side-plates subquadrate, 

 quite as wide distally as proximally, antero-distal corner abruptly 

 rounded, postero-distal corner broadly rounded, and margin 

 between almost straight. Third pair of epimeral plates of 

 metasome with antero-lateral comer produced downwards to a 

 conspicuous triangular projection, the posterior corner being 

 right-angled, and hind margin minutely ci'enulated.
