2. Cypris ciliata, nov. sp. Fig. A.1 a-g. 
Valves oval-elliptical, slightly narrowing anteriorly, high in the middle, 
very convex; greatest height less than two-thirds of the length. Margin 
finely denticulated on the inside, thickly fringed with fine hairs. Surface 
more or less hairy, minutely granular; when examined under a high power 
it appears closely reticulated. Colour very variable, ranging from whitish 
yellow to dark brown, more or less marked with brown, and sometimes with 
irregular black dots, varying chiefly with the nature of the mud of the 
pools in which the animals occur. Valves rather opaque, seldom semi- 
transparent. Sete of second pair of legs about as long as terminal joint. 
Post-abdominal rami long and slender; their claws long and pectinately 
toothed ; the uppermost seta nearly as long as the claw next it, terminal 
seta about half as long. 
Length 4, inch; height 41. inch. 
Very common in all stagnant fresh water near Dunedin. Wellington 
(T. W. Kirk). Probably the most abundant form in New Zealand. I have 
not found it in running streams. October to April or May. 
9. Cypris viridis, nov. sp. Fig. A.2 a-g. 
Valves broadly reniform, rounded at the extremities, slightly hollowed 
on the lower margin, elevated in the centre of the upper margin; greatest 
height about equal to three-fourths of the length. Viewed from above the 
valves are very convex posteriorly, broadly ovate in form, and tapering to 
the anterior extremity. Margins and surface clothed with hairs. Colour a 
dirty green, varying in intensity; substance of the valves quite opaque. 
Under a high power the surface appears to be minutely granular. Sets of 
second pair of legs short. Post-abdominal rami very slender; the claws 
unequal, and also very slender. Length j; inch; height 3 inch. 
Not uncommon in pools about Dunedin and Taieri Plain. 
To be found all the year round. I have taken it in blocks of ice, and 
found it quite lively as soon as its covering was thawed. 
4. Cypris littoralis, nov. sp. Fig A.8 a—b, and B.1 a-d. 
Valves narrow oblong, compressed; lower margin nearly straight, upper 
evenly aud slightly arched, highest in the middle; greatest height equal to 
less than half the length. Surface and margins quite smooth. Colour 
yellowish-grey, dotted with irregular black or brown spots. Valves semi- 
transparent. Terminal sete of second pair of legs very long and glumose. 
Post-abdominal rami long, slender and smooth; the two large terminal 
claws bearing three stout teeth near their apex. 
Length jjin.; breadth jin. 
This minute and very distinet species was found in pools of brackish 
water at Blueskin, north of Dunedin. The specimen figured was a male ; e T.
