short haii's ; dactylos curved, as long as the palm. Second gnathopoda 

 larger than first ; carpus widely convex on its inferior margin, and together 

 with the more slender propodos bearing fringes of long setse ; dactylos 

 four-toothed at the extremity of its lower margin. Four anterior pairs of 

 pereiopoda diminishing in length posteriorly, but with basa progressively 

 widening. Fifth pair very long ; only the setse on its posterior margin 

 plumose, those on the anterior being simple. Posterior pair of pleopoda 

 reaching slightly beyond the telson, flattened, rounded, thickly covered with 

 short hairs, and bearing a few long setse. Telson broadly triangular, 

 notched at the apex. Length -14 in. 



Hab. Dredged in Dunedin harbour, 4-5 fathoms. 

 ENTOMOSTEACA. 

 Phyllopoda (?). 

 Genus Nebaliaj Leach. 



Antenna two pairs, large and ramiform ; eyes two, pedunculated ; feet 

 twelve pairs, eight branchial and four natatory ; carapace large, enclosing 

 head, thorax and part of abdomen, almost as in a bivalve shell. (Baird's

Fig. 10. 



Carapace extending back to about the third abdominal segment on the 

 sides, but with a wide dorsal sinus. Beak large and well-developed. Eyes 

 situated on moveable peduncles, and formed of numerous crystalline bodies 

 under a common cornea. The antennae furnished with numerous hau's on 

 their peduncles ; superior pair with a peduncle of two joints, the last of 

 which bears two appendages, consisting of (1) a short, triangular joint with 

 spines on its outer margin, and an oval ciliated plate, and (2) a slender 

 flagellum of several articulations, the number of which were not made out ; 

 inferior pair with a pedimcle of three stout joints, — the second bearing a 

 large tooth on its upper margin, the third furnished with rows of spines and 

 hairs on its outer margin, and a bunch of hairs at its extremity, — and a 

 slender flagellum, almost equal in length to the whole body, and consisting 

 of between seventy and eighty articulations. Branchial feet completely con- 

 cealed beneath the carapace. The third to the seventh (inclusive) abdo- 

 minal segments with their posterior margins finely dentated. Peduncles of 

 the natatory feet largely developed, then- branches with a row of spines on 

 each outer margin. Caudal appendages with a row of spines on each side, 

 and terminated by several long and minutely plumose filaments. Carapace 

 semi-transparent, whole body pale-yellow in colour. Length -35 inch. 



Hab. Dunedin harbour, 4-5 fathoms. Stewart Island, 10. fathoms.
