chelate, palm even (fig. 1, d). In other respects the animal was exactly 
like the other two specimens; whether the difference in the gnathopoda in- 
dicates a difference of sex or not I cannot say. 
Genus Podocerus. 
Podocerus latipes, sp.nov. Pl. xix., fig. 2, a to d. 
Male.—Second gnathopoda stout, propodos produced inferiorly into a 
stout broad process defining the palm, which is deeply indented ; dactylos 
strong, inner edge serrated proximally, but with distal part smooth. Fourth 
pereiopoda with all the joints much expanded, all except the propodos being 
as broad as long. Other pereiopoda normal. In all other respects closely 
. resembling Podocerus frequens 
Fenale.—Differs in having the second gnathopoda not produced as in 
male, palm concave and defined by two stout sete. 
Colour, yellowish-white. Length about + inch. 
Hab. Lyttelton Harbour. 
This species may prove to be only a variety of P. frequens. I should 
without hesitation have considered it as such had it not differed in the 
second gnathopoda as well as in the fourth pereiopoda. The peculiar ex- 
pansion of the fourth pereiopoda appears to be subject to considerable varia- 
tion, probably it increases with the age of the animal. I am quite ignorant 
of the function of these expanded pereiopoda. 
Genus Paransenia, novum. 
Antenne subequal, superior with a secondary appendage, both with 
multiarticulate flagella. Appendage of mandible of three broad setose 
joints, as in Podocerus. Maxillipedes with well developed plates on ischios 
and meros. Gnathopoda sub-chelate, first small in both sexes, second 
small in female, very large in male. Last pair of pleopoda biramous, 
rami styliform. Telson single, ending posteriorly in two conical pro- 
jections. 
. I have made this genus to include three species found in Lyttelton 
Harbour—namely, P. typica, sp. nov., P. longimanus, sp. nov., and P. denti- 
fera= Moera dentifera, Haswell. It appears to bear a close resemblance to 
Nenia, Spence Bate, but differs in possessing a —— appendage on the 
upper antenna, and in the form of the telson. 
In P. typica and P. dentifera the cox® of the third segment of the 
pereion is large, and produced along the inferior edge of the coxe 
of the second segment in the male, while the cox® of the female are 
normal. P. longimanus has the coxe normal both in the male and in 
the female. 
In the description of P. dentifera I have embodied Mr. Haswell’s de- 
scription, but have added to and altered it where I thought necessary,
