and wide ; the third joint expanded distally ; dactylus wide at the base, the inner 

 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 perceopods : 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 perseopods 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, 7 mm. 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.
