1886. ] ENTOMOSTRACA FROM SOUTH AUSTRALIA. 91 
CHLAMYDOTHECA AUSTRALIS, 0. sp. (Plate IX. figs. 4-8.) 
Shell, seen from the side, subovate, greatest height equal to rather 
more than half the length, and situated in the middle, anterior 
extremity rounded, produced at the inferior angle so as to forma 
ventral beak, posterior extremity narrower, rounded, dorsal margin 
boldly arched, ventral slightly sinuated in the middle, more deeply 
in front, behind the beak ; seen from above, the outline is ovate, 
twice as long as broad, anterior extremity forming a large, broad, 
obtusely-pointed, and twisted prominence, posterior slightly narrowed 
and produced, but rounded off. The valves are unequal, the left 
being the larger, overlapping on the ventral, and less distinctly on 
the dorsal margin. The outline of the right valve is more evenly 
rounded than that of the left, presenting no ventral beak nor sinua- 
tion, nor are the margins, either ventral or dorsal, so much incurved ; 
the inner aspect of the valves shows shelving flanges both before and 
behind, and in that of the left side there is a curious twisted ridge 
separating the anterior beaked portion from the body of the shell. 
The substance of the shell is rather thick ; surface closely marked 
with small circular impressions ; colour fuscous. Length +1, of an 
inch. The specimens are all empty shells, so that the structure of 
the soft parts is as yet unknown.

Shell very tumid; width and height about equal, length about 
one fourth greater. Seen from the side, subcircular, highest in the 
middle, extremities broadly rounded, dorsal margin excessively 
arched, ventral nearly straight in the middle; seen from above very 
broadly ovate, obtusely pointed in front, the hinder part forming 
almost a complete circle; end view subcircular, obscurely pointed 
above, slightly keeled and emarginate below. Surface smooth, beset 
with small impressed circular puncta; colour olivaceous, clouded 
irregularly with darker patches. Anterior margins of the valves 
slightly crenulated. Length ;\ of an inch.

2. CYPRIDOPSIS FUNEBRIS, n. sp. (Plate VIII. figs. 7-9.) 
Shell, seen from the side, subtriangular ; greatest height a little in 
front of the middle and equal to nearly two thirds of the length; 
extremities rounded, the anterior wide, posterior narrower and not so 
well rounded, dorsal margin elevated and almost gibbous near the 
middle, thence sloping almost in a straight line backwards, and with 
a gentle curve towards the front, ventral almost straight ; seen from 
above, ovate, widest in the middle, width equal to two thirds of the
