blunt apices ; external margins of all the joints ciliated. Lamine of the fifth pair of 
feet (fig. 5) broad, subovate, nearly equal in length; margins of the external lamina 
finely ciliated, and bearing six subequal apical sete; inner lamina with five sete on 
its subtruncate apical margin. Abdominal segments slightly overlapping each other, 
but altogether devoid of sete or serrulations Male unknown. 
Hab. Otago Harbour, between tide-marks. One specimen only.

1. HARPACcTICUS GLABER, sp. nov. (Plate XII. figs. 6-11.) 
Female.—In general appearance like H. chelifer. Antennules (fig. 6) slender, 
moderately setiferous, eight-jointed ; lengths of the joints as in the following formula :

a small two-jointed branch, extremity of the last joint abruptly truncated and bearing 
two long, rigid, finely pectinated spines and four slender geniculated sete; posterior 
foot-jaw (fig. 8) almost exactly similar to that of H. chelifer. Outer branch of the 
first pair of feet elongated, two-jointed, terminating in three subequal, blunt, slightly 
curved and very finely pectinated claws; outer margins very sparingly ciliated ; each 
joint bearing within a short distance of its distal end a single short marginal seta: 
inner branch terminating in a strong slightly curved claw; the long first joint slightly 
ciliated and having near its apex a slender seta. Feet of the fifth pair two-jointed 
(fig. 10), basal joint wide, its inner portion distally produced and giving attachment 
to three long sete; terminal joint much narrower, margins ciliated, with three long 
sete at the apex and one on the outer edge. The spines of the swimming-feet, like 
those of the first pair and of the antenne, are minutely pectinated. The margins of 
the abdominal segments (fig. 11) are smooth except for a few minute hairs at the 
lateral angles and on the caudal lamine; principal tail-sete very long. 
Hab. Otago Harbour. One specimen taken in the surface-net. 
From #. chelifer this species may be distinguished by the number and comparative 
lengths of the joints of the antennules, by the armature of the antenne, the non- 
spinous margins of the first pair of feet, the different build of the fifth pair, and the 
almost smooth margins of the abdominal somites. There seem to be points of 
difference also in the mandibles and maxille, but these I have not clearly made out. 
Antenne (fig. 7) stout, nearly as long as the antennules, bearing
