Crustacea.] SUBANTARCTIC ISLANDS OF NEW ZEALAND. 651 



from the figures and descriptions given by these two authors, the females of the 

 two species are probably almost identical. Miss Harriet Richardson has recorded 

 H. australis from Booth Wandel Island, and has described the male, which was 

 previously unknown, as Hodgson's three speci- 

 mens were all females. 



In both species the male differs from the 

 female in the great size and peculiar form of 

 the first pair of legs, and from the figure given 

 by Miss Richardson it is evident that these 

 appendages in H. neozelanica (fig. 14a) differ 

 from those of H. antarctica, being, as her 



figure (see fig. 146) shows, of distinctly dif- Fig. U.—Haliacris neozelanica.

the males and females of his species resemble ''^- ""Ji^li^mS^^^Zt'' ^"' ''" "^ "''' 

 each other in the structure of the first pair 



of legs ; but, as Miss Richardson says, it is probable that his specimens " vier

 developed first pair of legs was really unknown to him.

A few small specimens were obtained in Perseverance Harbour, Campbell Island, 

 dredged in 8 fathoms ; others, from Auckland Island, are in Mr. G. M. Thomson's 

 collection ; and the species has also been recorded from Auckland Islands by 

 Hutton. It is common on the New Zealand coasts, and is closely allied to, if 

 not identical with, C. hirtipes M. -Edwards, from the Cape of Good Hope.
