and wide ; the third joint expanded distally ; dactylus wide at the base, the imner 
margin pectinate. 
First gnathopods: First joint straight, subequal to the next four; second shorter 
than the third, which narrows distally to a rounded point; wrist triangular, about half 
as long as the hand, which is subquadrate, with transverse, rather convex, palm as 
long as the hind margin and defined by a group of spines. 
Second gnathopods: First joint straight, widening distally, almost as long as the 
next four; third joint oblong, ending behind in a blunted acute angle; wrist produced 
behind a little beyond the base of the hand ; this is subtriangular, nearly twice as long 
as the width at the palm, which is the widest part; front margin straight; distal half 
of hind margin slightly concave, ending in a tooth behind which is a short and a long 
spine defining the transverse, slightly convex and spinulose palm. 
First and second pereeopods: Similar; all the joints narrow. Side-plates of the 
first pair oblong, about twice as deep as wide, the angles rounded ; those of the second 
broadly subtriangular, more rounded behind than in front, the lower margin slightly 
concave or sinuous. 
Remaining perzeopods resembling the first and second, the first joints narrow. 
First uropods extending beyond the second, the rami subequal, shorter than the 
peduncle ; in the second pair the upper ramus is shorter than the lower. 
The single ramus of the third uropods is subequal to the peduncle, the first joint 
rather longer than the second. 
Telson as described above.

5 June, 1902, two; length of female with ova, 7mm. W.Q., 15 June, 1902, 
six young. Tent Island, 3 Jan., 1904, 20 fm., one. 
A better mounting of the mandible than was effected with the ‘Southern Cross’ 
specimen shows that the molar tubercle is well developed, with a toothed grinding 
surface. It must therefore be referred to the genus Oediceroides Stebbing. 
The mandibular palp has the second joint wider and about one-fourth longer than 
the third, being widest about one-third of its length from the base.
