HORN EXPEDITION—CRUSTACEA. 
24.3 
locality .—Between Ooclnadatta and Charlotte Waters, associated with Z. 
squirei. Eight spirit specimens, seven male and one female with ova. At Conlon’s 
Lagoon, near Aliee Springs, where numerous drietl carapaces of Z. squirei were 
found, none of Z. tatei were to be seen. 
We have much pleasure in associating with this species the name of Profes.sor 
Tate, the colleague of one of us during the Expedition, and to whom we are also 
much indebted for his kindly placing at our disposal named specimens of various 
Estheriadre. 
(8) Limnadopsis brunueus^ sp. nov. (Eigs. 28, 29). 
Carapace in general form resembling that of Z. tatei^ with the difference that 
the dorsal spines are not so strongly devehjped ; the umbones are slightly more 
prominent and the shell is more compressed. The lines of growth are from 30-34 
in number, prominent and standing out as whitish lines. The eolour of the dried 
carapace is very striking, being of a rich brown, excepting for a broad band of 
lighter colour extending round the margin, excepting in the region of the umbo. 
The carapace looks exactly as if it were formed of tortoise shell, whereas that of 
Z. squirei and of Z. iatei are pale horny. Whole surface minutely and irregularly 
pustulate. 
Measurements of average specimen :—Length, 10 mm.; height, 6 mm.; thick¬ 
ness, L5 mm. 
Locality .—Four dried specimens from Knuckey’s Lagoon, near Port Darwin, 
Northern Territory. We are indebted to Professor R. Tate for the specimens.
