the 3rd, 4th, 5th, and Ist; which is the shortest of all; hairs most 
numerous on the three last joints. Ovigerous legs tolerably 
long and stout, one and a-third times as long as body ;?the 4th, 
5th, and 6th joints being nearly the same length. The four last 
joints are about the same length ;. claw slender, and about % as 
long as lasr joint. First three joints almost entirely smooth, 4th 
with a row of hairs at the end; 5th and 6th furnished with 
numerous spines ; last four joints with hairs only at the distal 
extremity. The spines of the four last joints are of a very 
irregular shape, and their numbers are respectively 10, 8, 5, 7. 
Spines of the claw not very strong. 
Legs three times as long as the body (36 mm. in a body of 
12 mm.) ; 2nd joint longer than Ist and 3rd, and swollen; 4th 
joint also very considerably swollen (with the ovaries), 5th and 
6th joints of nearly the same length, a little longer than the 4th; 
of the two tarsal joints, which are together nearly % the length 
of the 6th joint; the Ist is longer than the 2nd ; claw half the 
length of the 2nd tarsal joint, auxiliary claws wanting; 4th 
joint of the leg sparsely hairy, 5th a little more so, 6th very 
hairy, and shows some strong spines at the extremity; the tarsal 
joints covered with very minute hairs. Genital openings large 
and easily seen. 
Habitat—Dredged in lat. 40° 28’ S., long. 177° 43’ E., from 
a depth of 1100 fathoms. 
GENUS OORHYNCHUS, Hoek. 
Proboscis ovate, inserted ventrally on the cephalothorax at a 
considerable distance from the front margin. Mandibles rudi- 
mentary ; palpi 9-jointed. Ovigerous legs 10-jointed, the four 
last jointsnotfurnished with one ormore rows of denticulate spines. 
The following is the only species :— 
1. Oorhynchus aucklandie, Hoek. (lc. p. 59, Pl. VIL, figs. 
1-7).—Cephalothoracic segment short, but very broad, furnished 
at the front with a long cylindrical oculiferous tubercle, which 
projects horizontally beyond the extremity of the proboscis ; 
eyes four, two placed dorsally, two smaller ventrally. Cephalo- 
thorax armed at the corners with curiously-shaped spines, also 
projecting forwards, and bearing a couple of long hairs placed 
on small knobs above the attachment of the first pair of legs. 
Similar pairs of hairs on their spines also on the two following 
thoracic segments on the dorsal surface; rest of the body 
entirely smooth. Three thoracic segments small, lateral pro- 
cesses separated by small intervals. Abdomen very long, one 
and a-half times as long as proboscis, furnished on both sides 
with a row of projecting hairs. Proboscis ovate, bearing a 
small triangular mouth surrounded by slightly swollen lips. 
Mandibles represented by I-jointed robust club-shaped 
bodies, placed at the front margin of the cephalothorax, on both 
sides of the oculiferous tubercle ; covered all round with strong 
hairs projecting at right angles. Palpi 9g-jointed, placed close to 
and on both sides of the proboscis ; first joint very short, second —
