This species is very distinct in general shape from any European form, 
which are all more or less acutely produced inferiorly, and it also has the 
antenne very much shorter than is usual in the genus, 
Fam. IT. Lynceide. 
Superior antennz very short; inferior of moderate size, branched, each 
branch three-jointed ; legs five pairs; eye single, with a black spot in front; 
intestine convoluted, having one complete turn and a half, 
Genus I. Chydorus, Leach. 
Nearly spherical in shape; beak very long and sharp, curved downwards; 
inferior antenns very short. 
1. Chydorus minutus, nov. sp. Fig. E.3 a. 
. Carapace broadly oblong in young specimens, becoming more spherical 
in adults, dorsally rounded ; antero-inferior margin oblique, fringed with 
rather long cilia. Beak long, very acute. Eye rather small; eye-spot not 
half as large. Superior antenne very small, blunt, with a few very delicate 
sete. Inferior antenne short; lower branch with two sete from extremity 
of last joint; upper branch with one seta from the penultimate joint, and 
three from the last jomt. Abdomen strongly serrated on the inferior 
margin, with the terminal claws short and curved. The postero-dorsal 
border of the abdomen furnished with two filaments. Length about zty of 
an inch. 
Very common in ditches, ponds &c., near Dunedin, from October to May. 
In the larger specimen figured, a solitary young one was inside the 
carapace of the parent. This was well-developed, having the eye and eye- 
spot prominent, and apparently all the limbs perfect.
