252 Transactions.—Zoology. 
Examination of other portions of the Islands, and particularly the use 
of the dredge at various depths of the ocean, will certainly reveal many 
other forms. 
For subsequent reference, I have here tabulated the characters of the 
whole family. 
Sub-class Entomostraca. 
Legion I. Lophyropoda. Branchie attached to the organs of the mouth ; 
legs few, not exceeding five pairs, serving for locomotion; articulations 
mostly more or less cylindrical; antenns two pairs, one pair used as organs 
of motion. 
Order I. Ostracoda. Shell consisting of 2 valves, entirely enclosing the 
body ; feet 1-3 pairs, adapted for progression ; no external ovary. 
Sect. I. Podocopa. Inferior antenne simple, subpediform, geniculate, 
clawed at the end. 
Fam. 1. Cypridze. Superior antenne mostly seven-jointed, with a 
dense brush of long setze; eye single; feet two pairs, the last bent up 
between the valves ; abdominal rami two, elongate, clawed at the end. 
Genus I, Cypris, Müller. 
Upper antennz seven-jointed, with numerous long plumose sete. 
Lower antenne five-jointed, furnished with a brush of sete, and termi- 
nated by four long, serrated claws. Second pair of jaws possessing a 
branchial plate, and a sub-conical obscurely-jointed palpus, ending in three 
long sete.  Post-abdominal rami long and slender, terminating in two 
strong, curved claws. Animals free-swimming, mostly found in fresh or 
slightly brackish water. 
1. Cypris nove-zealandia, Baird. 
Cypris nove-zealandiz, Baird. Dieffenbach’s N. Z., vol. ii, p. 268. 
“Shell ovate, elongated, both extremities of the same size, somewhat 
turgid and slightly sinuated in the centre of anterior margin, white, smooth 
and shining, perfectly free from hairs.” 
This may be the species described next, as the valves bleach after the 
animal dies, and lose their hairs. The shape, however, is not quite the 
same, and the whole description is too meagre to found any identification 
upon. 
The following three species belong to Brady’s Section a, and agree in the 
following characters :— 
* Sete of lower antenne plumose, subequal, reaching about as far as, 
or only slightly beyond, the apex of the terminal claws. Second foot 
terminating in a short, hooked claw, and one or more moderately long 
sete,”
