A single small specimen was obtained in rock-pools at the Snares. The species 



is known from Tasmania and various parts of the east coast of Australia and from New 



Zealand. Mr. Walker has also recorded it from Cape Adare and from the winter 



quarters of the " Discovery " in McMurdo Strait. It is probably pretty closely 



allied to L. consanguinea, Stebbing, from Kerguelen and Heard Islands. 



Fam. Oedicerotidae. 



Genus Carolobatea, Stebbing, 1899. 



Distribution. — Contains only the following species, from New Zealand and 

 Kerguelen. 



Carolobatea novae-zealandiae (Dana).

A few specimens of this species, mostly of small size, were collected at Carnley 

 Harbour, Auckland Island. They agree with a species occasionally taken with the 

 surface-net on the coasts of New Zealand which I had previously identified with 

 tolerable certainty as Oediceros novi-zealandiae, Dana. It also agrees very closely 

 indeed with Halimedon schneideri, Stebbing, from Kerguelen, though Stebbing' s 

 description was taken from a female, probably immature, and does not show the 

 character of the second antenna as it 

 appears in the fully matured male. 



In this species there is very great 

 variation in the lengths of the an- 

 tennae, particularly of the second an- 

 tennae, and of the fifth peraeopods, 

 according to the age of the animal. 

 In younger specimens both antennae 

 are quite short, and agree well with 

 the description given by Stebbing. 

 In older specimens the upper antenna 

 is somewhat increased in length, and 

 has the flagellum rather markedly 

 thickened, so that most of the joints 

 of the flagellum become nearly as 

 broad as long ; the second antenna is longer and more slender, and the flagellum is 

 greatly elongated, until the whole antenna may about equal the length of the body ;
