HALICARCINUS HUTTONI Filhol. 
Halicarcinus huttom Filhol, Mission de |’Ile Campbell, 1885, p. 
ago. pl. xvi, fie. 1. 
Lenz, Zool. Jahrb, xiv., 1901, p. 469. 
Two males and four females from Station 75, all small; a 
female bearing eggs having the carapace 6mm. broad and its 
length a trifle less. 
These specimens I refer with very little hesitation to Filhol’s 
species. Lenz considers this only a young form of H. planatus 
var. tridentatus (Jaeq. et Luc.) but some of my specimens are 
adult females with eggs, and they can be readily distinguished 
from even young forms of var. tridentatus Jaeq. et Luc. They 
differ in shape of the carapace which is only slightly broader 
than long and narrows a little towards the front, and in having 
the three teeth of the front more nearly on a level with the 
surface of the carapace though the margin of the carapace 
is continued across the base of the front as a somewhat 
indistinct line; the teeth themselves are much longer and more 
slender than in var. tridentatus; they are hairy towards the end 
and some hairs are also present on the surface of the carapace, 
while the legs are much more abundantly furnished with hairs 
than in var. tridentatus. In the males that I have been able to 
examine the chelipeds are much smaller and Have the hands 
less swollen than in var. tridentatus and the ischium bears at 
its distal end three fairly prominent teeth, one on the upper 
margin and one at each side. 
In the size, greater hairiness, and in the very long and slender 
dactyls of the ambulatory legs my specimens seem to closely 
resemble those from Jervis Bay which are referred by 
Mr. Stebbing to H. ovatus Stimpson. This and other points 
in connection with the N.Z Hymenosomide must however stand 
over for solution at some future time.

E. kirki Filhol, loc. cit., 1885, p. 405, pl. xlvii., figs. 5-9. 
Two specimens, both females with eggs, from Stewart. Island. 
E. hirki Filhol, as deseribed and figured, differs a little in the 
shape of the carapace but is I think too near to be considered 
a separate species. H. producta appears to be a variable species, 
as Lenz has already pointed out.
